Background Paragraph: The water level is seasonal, being lowered by about 10 feet (3.0 m) over the winter. The reservoir fills in the spring from snow melt and underground springs. The lake is usually at full level by late spring, but in the occasional years of low snow melt and low rainfall, it may remain up to several feet below its typical level. Water is let out of the lake in the fall so that ice will not damage docks and other structures around the lake. This also leads to excellent water quality, as a significant portion of the water is replaced every year. 
Story: The water level in Large Lake was high in March, 3 feet higher in April, and 7 feet higher still in May. It dropped to a much lower level in September, October and November, when they released a significant portion of the water as a yearly chore. 
Question: When was the water quality better in October or in March?
Output: in March.
Background Paragraph: Beginning in the late 1970’s, ozone depletion was recognized as a significant environmental issue. The most dramatic decrease in ozone occurs seasonally over the continent of Antarctica. The size and duration of the ozone hole steadily increased, with the largest hole recorded in 2006. Fortunately, most countries have recognized the danger of CFCs and dramatically curtailed their use in recent years. It is hoped that ozone depletion will slow and that the ozone layer may eventually be restored to its earlier levels. 
Story: Ben and Harry were studying about the climatic history of Earth. Ben was more attracted to learning about early Ice Ages, while Harry was curious about the Earth atmosphere and read about ozone depletion and its consequences. 
Question: Which person learned more about the size of the ozone hole over Antarctica?
Output: Harry.
Background Paragraph: While people have been able to prevent certain viral diseases by vaccinations for many hundreds of years, the development of antiviral drugs to treat viral diseases is a relatively recent development. Antiviral drugs are medications used specifically for treating the symptoms of viral infections. The first antiviral drug was interferon , a substance that is naturally produced by certain immune cells when an infection is detected. Over the past twenty years the development of antiretroviral drugs (also known as antiretroviral therapy, or ART) has increased rapidly. This has been driven by the AIDS epidemic. 
Story: Two pharma students read about antiviral and antibacterial drugs. Manny read about antiviral drugs, while George read about bacteria and antibacterial drugs. 
Question: Which student read how people have been able to prevent certain viral diseases by vaccinations for many hundreds of years?
Output: Manny.
Background Paragraph: Old age begins in the mid-60s and lasts until the end of life. Most people over 65 have retired from work, freeing up their time for hobbies, grandchildren, and other interests. Stamina, strength, reflex time, and the senses all decline during old age, and the number of brain cells decreases as well. The immune system becomes less efficient, increasing the risk of serious illnesses such as cancer and pneumonia. Diseases such as Alzheimer’s disease that cause loss of mental function also become more common. 
Story: Doctors studied two groups of individuals: group O with people over 65, and group S with people under 65 years old. They published the results in a magazine. 
Question: Which group had fewer people with decreased stamina?
Output: group S.
Background Paragraph: If only 1.0 mL of 0.10 M hydrochloric acid is added to 1.0 L of pure water the pH drops drastically from 7.0 to 4.0. This is a 1000-fold increase in the acidity of the solution. For many purposes, it is desirable to have a solution which is capable of resisting such large changes in pH when relatively small amounts of acid or base are added to them. Such a solution is called a buffer. A buffer is a solution of a weak acid or a base and its salt. Both components must be present for the system to act as a buffer to resist changes in pH. Commercial buffer solutions, which have a wide variety of pH values, can be obtained. 
Story: John is a scientist in a large pharmaceutical company. He devices many useful products using his knowledge of chemistry. Today, he has four solutions in front of him, solution A, solution B, solution C, and solution D. Solution A is a buffer, but solution B is not a buffer. Solution C is acidic, but solution D is not acidic. He needs to figure out what each solution does. 
Question: Would solution C increase or decrease the pH of pure water?
Output: decrease.
Background Paragraph: Friction between the atmosphere and the Earth's surface causes a 20% reduction in the wind at the surface of the Earth.[10] Surface roughness also leads to significant variation of wind speeds. Over land, winds maximize at hill or mountain crests, while sheltering leads to lower wind speeds in valleys and lee slopes.[11] Compared to over water, maximum sustained winds over land average 8% lower.[12] More specifically, over a city or rough terrain, the wind gradient effect could cause a reduction of 40% to 50% of the geostrophic wind speed aloft; while over open water or ice, the reduction is between 10% and 30%.[8][13][14]. 
Story: Bill is going on vacation this week, and is visiting two local sites. One, is Deep Valley, and the other is Mount Tall. He will be going to Deep Valley on Monday and Tuesday, and then visit Mount Tall on Thursday and Friday. He has decided that on his trip he wants to fly his kite at some point, but also wants to have a picnic on the other days. He would prefer an area of high wind for flying his kite, and an area of low winds to have his picnic so his food doesn't blow asunder. 
Question: Will there be more or less wind where Bill goes on Tuesday than Friday?
Output: less.
Background Paragraph: It would be very unadvisable to place a can of soup over a campfire without venting the can. As the can heats up, it may explode. The kinetic-molecular theory explains why. The air inside the rigid can of soup is given more kinetic energy by the heat coming from the campfire. The kinetic energy causes the air molecules to move faster and they impact the container walls more frequently and with more force. The increase in pressure inside may eventually exceed the strength of the can and it will explode. An additional factor is that the soup may begin boiling which will then aid even more gas and more pressure to the inside of the can. 
Story: A team of hikers split into two groups. Group Jones hiked north and camped there  overnight. Group George went east. Both groups made campfires and heated cans of soups. Group Jones didn't make holes in the cans, so the cans exploded. The others heated their soup cans the right way, by venting them first. 
Question: Which group's cans had the air molecules inside move faster?
Output: Jones.
Background Paragraph: The quantity of small plastic fragments floating in the north-east Pacific Ocean increased a hundredfold between 1972 and 2012.Marine pollution is a generic term for the harmful entry into the ocean of chemicals or particles. The main culprits are those using the rivers for disposing of their waste. The rivers then empty into the ocean, often also bringing chemicals used as fertilizers in agriculture. The excess of oxygen-depleting chemicals in the water leads to hypoxia and the creation of a dead zone.Marine debris, also known as marine litter, is human-created waste that has ended up floating in a lake, sea, ocean, or waterway. Oceanic debris tends to accumulate at the center of gyres and coastlines, frequently washing aground where it is known as beach litter.In addition, the Pacific Ocean has served as the crash site of satellites, including Mars 96, Fobos-Grunt, and Upper Atmosphere Research Satellite. 
Story: Ecuador and Panama both had beautiful rivers flowing into the Pacific ocean. Ecuador uses their river to dispose of their waste while Panama is very eco-friendly and doesn't do that. 
Question: Which country causes more hypoxia in the ocean?
Output: Ecuador.
Background Paragraph: As Figure above shows, the distance between particles is much smaller for the solid and liquid states than for the gas state. In the solid state, particles are fixed in place, while particles are more free to move in the liquid and gas states. The particles in the solid and liquid states “stick together,” but in the gas state, they move freely about the container. In general, it requires energy to separate individual particles. If we want to make a solid adopt a liquid form, we can add energy in the form of heat, increasing the temperature of the substance. Conversely, if we want to convert a substance from a gas to a liquid or from a liquid to a solid, we remove energy from the system and decrease the temperature. Pressure also plays an important role in changes of state, which will be discussed later on. We will study these difference in greater detail in the chapter States of Matter. 
Story: John is studying the different states of matter. Today, he has a matter in three states in front of him, state A, state B, and state C. State A is in solid state. State B is in liquid state. And, state C is in gaseous state. He needs to determine the properties of each state. 
Question: Would state C have less or more distance between particles than state B?
Output: more.
Background Paragraph: Compared to conventional milk production, organic milk production tends to have lower eutrophication potential per ton of milk or per hectare of farmland, because it potentially reduces leaching of nitrates (NO3−) and phosphates (PO4−) due to lower fertilizer application rates. Because organic milk production reduces pesticides utilization, it increases land use per ton of milk due to decreased crop yields per hectare. Mainly due to the lower level of concentrates given to cows in organic herds, organic dairy farms generally produce less milk per cow than conventional dairy farms. Because of the increased use of roughage and the, on-average, lower milk production level per cow, some research has connected organic milk production with increases in the emission of methane.Animal welfare issues vary among dairy farms and are not necessarily related to the way of producing milk (organically or conventionally). 
Story: Jimmy is currently shopping at his local grocery store during his weekly trip to get food and other necessities. He first picks up some frozen pizzas, his favorite meal when he is feeling lazy after work, and then stops off to pick up a loaf of bread. He then walks over to the dairy section to pick up some cheese for his lunches. Jimmy never buys milk, but today he has a sudden urge to get some. He walks over to the milk refrigerators and looks at all the options. He is currently debating between two brands, Luchene and Jean's. While trying to decide, he notices a sticker on the Luchene gallon that says "organic," but is unable to find any such indication on the gallon of Jean's milk. After asking an employee, it is confirmed that Jean's is not organic milk. Unable to make up his mind, Jimmy simply leaves without buying any milk. 
Question: Which brand of milk has higher eutrophication potential per hectare of farmland?
Output: Jean's.
Background Paragraph: Earth is a restless planet. Heat in the Earth’s interior causes giant plates of crust to move around on the surface. The crashing and smashing of these plates leads to nearly all of the geological activity we see. Plate collisions bring us volcanoes and earthquakes, mountain ranges, and many resources. Seafloor forms as plates move apart. Some of Earth’s most beautiful landscapes come from plate tectonics. The Grand Tetons in Wyoming rose up as the Farallon Plate sunk beneath the North American Plate during the Laramide orogeny. 
Story: John was studying the plate tectonics of earth. He specifically selected two locations, location A and location B. He noticed that location A had lot of plate tectonics activities, but location B didn't have much of that. He wondered how that would make difference in those locations' characteristics. 
Question: In location A would seafloor more likely or less likely form than in location B?
Output: more likely.
Background Paragraph: The Tasmanian devil is a nocturnal and crepuscular hunter, spending the days in dense bush or in a hole.[64] It has been speculated that nocturnalism may have been adopted to avoid predation by eagles and humans.[65] Young devils are predominantly crepuscular.[66] There is no evidence of torpor.[67]

Young devils can climb trees, but this becomes more difficult as they grow larger.[68][69] Devils can scale trees of trunk diameter larger than 40 cm (16 in), which tend to have no small side branches to hang onto, up to a height of around 2.5–3 m (8.2–9.8 ft). Devils that are yet to reach maturity can climb shrubs to a height of 4 metres (13.1 ft), and can climb a tree to 7 m (23 ft) if it is not vertical.[70] Adult devils may eat young devils if they are very hungry, so this climbing behaviour may be an adaptation to allow young devils to escape.[71] Devils can also swim and have been observed crossing rivers that are 50 metres (160 ft) in width, including icy cold waterways, apparently enthusiastically. 
Story: The scientists examined both the Eastern and the Western slopes of the mountain. They reached the conclusion that the Western slope was inhabited by many more adult Tasmanian devils than the Eastern slope. 
Question: Which slope had fewer devils climbing up to 23ft?
Output: Western.
Background Paragraph: Lactose intolerance is due to the lack of enzyme lactase in the small intestines to break lactose down into glucose and galactose.[3] There are four types: primary, secondary, developmental, and congenital.[1] Primary lactose intolerance occurs as the amount of lactase declines as people age.[1] Secondary lactose intolerance is due to injury to the small intestine such as from infection, celiac disease, inflammatory bowel disease, or other diseases.[1][4] Developmental lactose intolerance may occur in premature babies and usually improves over a short period of time.[1] Congenital lactose intolerance is an extremely rare genetic disorder in which little or no lactase is made from birth.[1]. 
Story: David works for a large pharmaceutical company as a research scientist. He has devised a procedure which can detect lactose intolerance in patients easily. To test his procedure he picked up four subjects form a large pool of sample. The four subjects are subject A, subject B, subject C, and subject D. Subject A has primary lactose intolerance; subject B has secondary lactose intolerance; subject C has developmental lactose intolerance; and subject D has congenital lactose intolerance. 
Question: Which subject would most porbably be older, subject A or subject C?
Output: subject A.
Background Paragraph: Predators play an important role in an ecosystem. For example, if they did not exist, then a single species could become dominant over others. Grazers on a grassland keep grass from growing out of control. Predators can be keystone species . These are species that can have a large effect on the balance of organisms in an ecosystem. For example, if all of the wolves are removed from a population, then the population of deer or rabbits may increase. If there are too many deer, then they may decrease the amount of plants or grasses in the ecosystem. Decreased levels of producers may then have a detrimental effect on the whole ecosystem. In this example, the wolves would be a keystone species. 
Story: Karen studied animals in school. She started studying predators for a school presentation. She liked it. Her friend Molly liked cows, sheep and other herbivores, so she decided to do a presentation about grazers, and their role in nature. 
Question: Which girl learned less about animals that can have a large effect on the balance of organisms in an ecosystem?
Output: Molly.
Background Paragraph: One reason radiation is dangerous is that it can’t be detected with the senses. You normally can’t see it, smell it, hear it, or feel it. Fortunately, there are devices such as Geiger counters that can detect radiation. A Geiger counter, like the one in Figure below , has a tube that contains atoms of a gas. If radiation enters the tube, it turns gas atoms to ions that carry electric current. The current causes the Geiger counter to click. The faster the clicks occur, the higher the level of radiation. 
Story: David was visiting Japan. First, he went to Fukushima where the recent nuclear plant disaster happened. He found the city still had very high radiation. Then he visited Hiroshima. He found that Hiroshima had some low radiation. Finally, he visited the capital city Tokyo. He found that Tokyo did not have any radiation. 
Question: In which city the gas inside a Geiger counter would be ionized, Hiroshima or Tokyo?
Output: Hiroshima.
Background Paragraph: Friction between the atmosphere and the Earth's surface causes a 20% reduction in the wind at the surface of the Earth.[10] Surface roughness also leads to significant variation of wind speeds. Over land, winds maximize at hill or mountain crests, while sheltering leads to lower wind speeds in valleys and lee slopes.[11] Compared to over water, maximum sustained winds over land average 8% lower.[12] More specifically, over a city or rough terrain, the wind gradient effect could cause a reduction of 40% to 50% of the geostrophic wind speed aloft; while over open water or ice, the reduction is between 10% and 30%.[8][13][14]. 
Story: The Johnson Family is planning a couple of excursions next week. On Wednesday they will be going to Tulsa Valley, and on Friday they are going to Albert's Peak, a small mountain in the area. Mr. Johnson has been wanting to fly some kites if there are some good wind conditions for doing so. He also wants to treat his family to a picnic and would like a more serene setting, with little to no wind to disrupt their picnic. 
Question: Which place will more likely be more windy?
Output: Albert's Peak.
Background Paragraph: They feed on living hosts. As parasites , fungi live in or on other organisms and get their nutrients from their host. Parasitic fungi use enzymes to break down living tissue, which may causes illness in the host. Disease-causing fungi are parasitic. Recall that parasitism is a type of symbiotic relationship between organisms of different species in which one, the parasite, benefits from a close association with the other, the host, which is harmed. 
Story: Bill and Larry did some research on fungi. Larry researched saprophytic fungi, while Bill researched parasitic fungi. They later exchanged findings. 
Question: Which researcher learned more about fungi that live on other organisms?
Output: Bill.
Background Paragraph: Animals and some bacteria and fungi carry out lactic acid fermentation. Lactic acid is a waste product of this process. Our muscles perform lactic acid fermentation during strenuous exercise, since oxygen cannot be delivered to the muscles quickly enough. The buildup of lactic acid is believed to make your muscles sore after exercise. Bacteria that produce lactic acid are used to make cheese and yogurt. The lactic acid causes the proteins in milk to thicken. Lactic acid also causes tooth decay, because bacteria use the sugars in your mouth for energy. 
Story: Two groups of microbiology students studied about the fermentation process. Group A studied about alcoholic and acetic fermentation, while group B studied about lactic fermentation. 
Question: Which group learned more about proteins in milk thickening?
Output: group B.
Background Paragraph: Increased solar ultraviolet radiation resulting from the Antarctic ozone hole has reduced marine primary productivity (phytoplankton) by as much as 15% and has started damaging the DNA of some fish. Illegal, unreported, and unregulated fishing, especially the landing of an estimated five to six times more Patagonian toothfish than the regulated fishery, likely affects the sustainability of the stock. Long-line fishing for toothfish causes a high incidence of seabird mortality. 
Story: Red fishery and Brown fishery were both fishing for Patagonian toothfish. Red fishery was fishing illegally, while Brown fishery was regulated and lawful. 
Question: Which fishery did less unreported fishing?
Output: Brown.
Background Paragraph: Evidence from seismology, heat flow at the surface, and mineral physics is combined with the Earth's mass and moment of inertia to infer models of the Earth's interior – its composition, density, temperature, pressure. For example, the Earth's mean specific gravity (5.515) is far higher than the typical specific gravity of rocks at the surface (2.7–3.3), implying that the deeper material is denser. This is also implied by its low moment of inertia ( 0.33 M R2, compared to  0.4 M R2 for a sphere of constant density). However, some of the density increase is compression under the enormous pressures inside the Earth. The effect of pressure can be calculated using the Adams–Williamson equation. The conclusion is that pressure alone cannot account for the increase in density. Instead, we know that the Earth's core is composed of an alloy of iron and other minerals.Reconstructions of seismic waves in the deep interior of the Earth show that there are no S-waves in the outer core. This indicates that the outer core is liquid, because liquids cannot support shear. The outer core is liquid, and the motion of this highly conductive fluid generates the Earth's field. Earth's inner core, however, is solid because of the enormous pressure.Reconstruction of seismic reflections in the deep interior indicate some major discontinuities in seismic velocities that demarcate the major zones of the Earth: inner core, outer core, mantle, lithosphere and crust. The mantle itself is divided into the upper mantle, transition zone, lower mantle and D′′ layer. Between the crust and the mantle is the Mohorovičić discontinuity.The seismic model of the Earth does not by itself determine the composition of the layers. For a complete model of the Earth, mineral physics is needed to interpret seismic velocities in terms of composition. The mineral properties are temperature-dependent, so the geotherm must also be determined. This requires physical theory for thermal conduction and convection and the heat contribution of radioactive elements. The main model for the radial structure of the interior of the Earth is the preliminary reference Earth model (PREM). Some parts of this model have been updated by recent findings in mineral physics (see post-perovskite) and supplemented by seismic tomography. The mantle is mainly composed of silicates, and the boundaries between layers of the mantle are consistent with phase transitions.The mantle acts as a solid for seismic waves, but under high pressures and temperatures it deforms so that over millions of years it acts like a liquid. This makes plate tectonics possible. 
Story: John is a geologist. He was trying to figure out how the Earth's inner core is made. To that end, he compared earth's physical characteristics to available items. First he took a sample of surface rock, which he labeled as item B. Then he took a sphere of constant density, which he labeled as item C. Finally, he labeled the Earth as item A. 
Question: Which would have lower specific gravity, item A or item B?
Output: item B.
Background Paragraph: We discussed earlier some basic principles about the behavior of gases called the kinetic-molecular theory. Among other things, this theory suggests that gas molecules are in constant motion, and the average speed of the individual gas particles is dependent upon temperature – the higher the temperature, the faster the molecules move. It is not just gas particles that are in constant motion. The molecules and ions that make up liquids and solutions are also continually moving in nearly random directions. As a result, molecules and ions in a solution will collide with one another fairly frequently. As with gases, a temperature increase will produce an increase in the average particle speed. 
Story: Scientists are observing two of the same gases at different temperatures. They are observing the speed of the particles in the gases to see how fast they are moving. Gas A has particles moving very quickly, but Gas B has particles that are hardly moving at all. 
Question: Which gas is at a lower temperature?
Output: Gas B.
Background Paragraph: Greenhouse Effect: The solar energy reaching the surface of the Earth is concentrated in short wavelengths, which can easily penetrate the greenhouse gases, such as carbon dioxide and methane. The Earth, however, is cooler than the sun and it radiates its heat in the form of energy in the far infrared range. These longer wavelengths are partially absorbed by the greenhouse gases and some of the solar heat is returned to Earth. At a certain temperature these processes are in equilibrium and the surface temperature of the Earth is stable. However, if more greenhouse gases are put in the atmosphere the amount of trapped terrestrial radiation increases, leading to an increase in global temperature. 
Story: Two meteorologists were good friends and discussed diverse issues weekly. This week they will talk again. Tim read about the Greenhouse Effect while Norm read about the mini-Ice ages. 
Question: Which friend learned less about short wavelength energy?
Output: Norm.
Background Paragraph: Nearsightedness, or myopia, is the condition in which nearby objects are seen clearly, but distant objects appear blurry. The Figure below shows how it occurs. The eyeball is longer (from front to back) than normal. This causes images to be focused in front of the retina instead of on the retina. Myopia can be corrected with concave lenses. The lenses focus images farther back in the eye, so they fall on the retina instead of in front of it. 
Story: John and Keith are two friends. They went to see an ophthalmologist for an eye cheek up. The doctor found that John had myopia, but Keith had normal eyes. He advised them according to his findings. 
Question: Would Keith's eyeball more likely or less likely be longer than John's?
Output: less likely.
Background Paragraph: In the U.S., the majority of electricity is produced by burning coal or other fossil fuels. This causes air pollution, acid rain, and global warming. Fossil fuels are also limited and may eventually run out. Like fossil fuels, radioactive elements are limited. In fact, they are relatively rare, so they could run out sooner rather than later. On the other hand, nuclear fission does not release air pollution or cause the other environmental problems associated with burning fossil fuels. This is the major advantage of using nuclear fission as a source of energy. 
Story: Us and Canada are two friendly countries. Canada uses alternative methods to produce electricity while the US use more coal and oil. Both countries recently participated in a Global Warming Council. 
Question: Which country causes more air pollution?
Output: US.
Background Paragraph: Another major cause of extinction is global warming , which is also known as global climate change. During the past century, the Earth's average temperature has risen by almost 1°C (about 1.3°F). You may not think that is significant, but to organisms that live in the wild and are constantly adapting to their environments, any climate change can be hazardous. Recall that burning fossil fuels releases gasses into the atmosphere that warm the Earth. Our increased use of fossil fuels, such as coal and oil, is changing the Earth’s climate. Any long-term change in the climate can destroy the habitat of a species. Even a brief change in climate may be too stressful for an organism to survive. For example, if the seas increase in temperature, even briefly, it may be too warm for certain types of fish to reproduce. 
Story: Ken and Stacy are two engineers discussing their plans about what source of energy they should use to generate electricity in a new city they are helping design. Ken feels that they should use coal since it's reliable, abundant and relatively cheap. Stacy argues that they should use solar power because there is an infinite supply of solar energy. 
Question: Will Stacy's plan increase the temperature of the oceans more or less than Ken's?
Output: less.
Background Paragraph: Cholesterol can't dissolve in the blood. It has to be transported to and from the cells by carriers called lipoproteins. Low-density lipoprotein, or LDL, is known as "bad" cholesterol. High-density lipoprotein (HDL) is known as good cholesterol. When too much LDL cholesterol circulates in the blood, it can slowly build up in the inner walls of the arteries that feed the heart and brain. Together with other substances, it can form plaque, and lead to atherosclerosis. If a clot forms and blocks a narrowed artery, a heart attack or stroke can result. Cholesterol comes from the food you eat as well as being made by the body. To lower bad cholesterol, a diet low in saturated fat and dietary cholesterol should be followed. Regular aerobic exercise also lowers LDL cholesterol and increases HDL cholesterol. 
Story: Mary and Ben went in for a blood test. Ben had high cholesterol, so the Doctor recommended him to lower it. Mary had normal cholesterol levels. 
Question: Which person had less plaque in their arteries?
Output: Mary.
Background Paragraph: The mechanism describing the formation of the ozone layer was described by British mathematician Sydney Chapman in 1930. Molecular oxygen absorbs high energy sunlight in the UV-C region, at wavelengths shorter than about 240 nm. Radicals produced from the homolytically split oxygen molecules combine with molecular oxygen to form ozone. Ozone in turn is photolysed much more rapidly than molecular oxygen as it has a stronger absorption that occurs at longer wavelengths, where the solar emission is more intense. Ozone (O3) photolysis produces O and O2. The oxygen atom product combines with atmospheric molecular oxygen to reform O3, releasing heat. The rapid photolysis and reformation of ozone heats the stratosphere resulting in a temperature inversion. This increase of temperature with altitude is characteristic of the stratosphere; its resistance to vertical mixing means that it is stratified. Within the stratosphere temperatures increase with  altitude (see temperature inversion); the top of the stratosphere has a temperature of about 270 K (−3°C or 26.6°F). This vertical stratification, with warmer layers above and cooler layers below, makes the stratosphere dynamically stable: there is no regular convection and associated turbulence in this part of the atmosphere. However, exceptionally energetic convection processes, such as volcanic eruption columns and overshooting tops in severe supercell thunderstorms, may carry convection into the stratosphere on a very local and temporary basis. Overall the attenuation of solar UV at wavelengths that damage DNA by the ozone layer allows life to exist on the surface of the planet outside of the ocean. All air entering the stratosphere must pass through the tropopause, the temperature minimum that divides the troposphere and stratosphere. The rising air is literally freeze dried; the stratosphere is a very dry place. The top of the stratosphere is called the stratopause, above which the temperature decreases with height. 
Story: Barbara and Jane are two  students.  They both like meteorology. Barbara studies the formation of the ozone layer, while Jane studies about the stratosphere. 
Question: Which student learned more about (O3) photolysis?
Output: Barbara.
Background Paragraph: The intentional cultivation of arthropods and other small animals for human food, referred to as minilivestock, is now emerging in animal husbandry as an ecologically sound concept. However, the greatest contribution of arthropods to human food supply is by pollination. Three-fourths of the world’s flowering plants and about 35% of the world’s food crops depend on animal pollinators to reproduce and increase crop yields. More than 3,500 species of native bees pollinate crops. Some scientists estimate that one out of every three bites of food we eat exists because of animal pollinators, including birds and bats and arthropods like bees, butterflies and moths, and beetles and other insects. 
Story: Two neighboring villages practiced extensive agriculture for their food supply. Leaf village used the intentional cultivation of arthropods to help them get better harvests. Tree village didn't do that, they used conventional methods of growing their crops and got smaller harvests. 
Question: Which village used more minilivestocks for agriculture?
Output: Leaf.
Background Paragraph: Hepatitis B is a disease of the liver. It is caused by a virus called hepatitis B, which can be passed through sexual activity. Hepatitis B causes vomiting. It also causes yellowing of the skin and eyes. The disease goes away on its own in some people. Other people are sick for the rest of their lives. In these people, the virus usually damages the liver. It may also lead to liver cancer. Medicines can help prevent liver damage in these people. There is also a vaccine to protect against hepatitis B. 
Story: Keith is a doctor in a local hospital. Today, he is seeing three patients, patient A, patient B, and patient C. Patient A has been suffering from hepatitis B all his life; patient B is recovering from hepatitis B on his own; and patient C doesn't have hepatitis B. Keith would now compare the symptoms of these patients. 
Question: Would patient A more likely or less likely risk a damaged liver than patient B?
Output: more likely.
Background Paragraph: Arbuscular mycorrhizal fungi vary across many environmental gradients. Their tolerance to freezing and drying is known to shift between AM fungal taxa. AM fungi become less prevalent and diverse at higher soil nutrient and moisture concentrations, presumably because both plants allocate less carbon to AM fungi and AM fungi reallocate their resources to intraradical hyphae in these environmental conditions. Over the long term, these environmental conditions can even create local adaptation between plant hosts, AM fungi and the local soil nutrient concentrations. 
Story: Carrie bought two parcels of farmland. The Northern one had soil with lots of arbuscular mycorrhizal fungi, while the Southern parcel  had almost no traces of AM fungi. 
Question: Which parcel had more species of AM fungi in its soil?
Output: Northern.
Background Paragraph: Regions on the Earth's surface (or in its atmosphere) that are high above mean sea level are referred to as high altitude. High altitude is sometimes defined to begin at 2,400 meters (8,000 ft) above sea level.[5][6][7]

At high altitude, atmospheric pressure is lower than that at sea level. This is due to two competing physical effects: gravity, which causes the air to be as close as possible to the ground; and the heat content of the air, which causes the molecules to bounce off each other and expand.[8]. 
Story: There were two villages: Berg village situated at 3000 ft, at the base of the mountain, and Steep village, situated at 8500 feet. People visiting the area always stop in Berg village and feel great, but they feel bad and winded once they get to Steep village. 
Question: Which village has a higher oxygen content in the air?
Output: Berg.
Background Paragraph: Storing large volumes of data – When storing XML to either file or database, the volume of data a system produces can often exceed reasonable limits, with a number of detriments: the access times go up as more data is read, CPU load goes up as XML data takes more power to process, and storage costs go up. By storing XML data in Fast Infoset format, data volume may be reduced by as much as 80 percent. 
Story: Ian had a busy day storing XML. At 4 PM, he stored 11100 Gigabytes to the database. At 5 PM, he stored 22200 Gigabytes to the database. At 6 PM, he stored 33300 Gigabytes to the database. At 7 PM, he got dinner. At 8 PM, he stored 44400 Gigabytes to the database. At 9 PM, he stored 55500 Gigabytes to the database. At 10 PM, he went to sleep to finish storing XML in the morning. 
Question: What time did storage costs go up:  9 PM or 10 PM?
Output: 9 PM.
Background Paragraph: Allergy symptoms can range from mild to severe. Mild symptoms might include itchy eyes, sneezing, and a runny nose. Severe symptoms can cause difficulty breathing, which may be life threatening. Keep in mind that it is the immune system and not the allergen that causes the allergy symptoms. Allergy symptoms can be treated with medications such as antihistamines. Severe allergic reactions may require an injection of the hormone epinephrine. These treatments lessen or counter the immune system’s response. 
Story: The doctors used used the newly discovered allergy medicine on two groups of people. As a result, group Alpha experienced mild allergy symptoms, while group Beta continued experiencing severe allergy symptoms and remained hospitalized. 
Question: Which group experienced difficulty breathing?
Output: group Beta.
Background Paragraph: Because of human activities, there is more carbon dioxide in the atmosphere today than in the past hundreds of thousands of years. Burning fossil fuels and has released great quantities of carbon dioxide into the atmosphere. Cutting forests and clearing land has also increased carbon dioxide into the atmosphere because these activities reduce the number of autotrophic organisms that use up carbon dioxide in photosynthesis. In addition, clearing often involves burning, which releases carbon dioxide that was previously stored in autotrophs. 
Story: When comparing village A from ten thousand years ago to village B from today, we reached the conclusion that today's villagers release much more carbon into the atmosphere by their activities. 
Question: Which village cleared less land?
Output: village A.
Background Paragraph: Enzymes increase the rate of chemical reactions by reducing the amount of activation energy needed for reactants to start reacting. One way this can happen is modeled in the Figure below . Enzymes aren’t changed or used up in the reactions they catalyze, so they can be used to speed up the same reaction over and over again. Each enzyme is highly specific for the particular reaction is catalyzes, so enzymes are very effective. A reaction that would take many years to occur without its enzyme might occur in a split second with the enzyme. Enzymes are also very efficient, so waste products rarely form. 
Story: A scientist is testing chemical reactions. At first he tries mixing two chemicals together at a temperature of 85 degrees Celsius and labels it Trial A. He records the time for the reaction to complete at 2 minutes. Knowing that this isn't the temperature users at home will be combining the chemicals at he tries the reaction again at a more modest 65 degrees Celsius and labels this trial B. Noting this temperature the reaction takes almost 4 times as long which is completely unacceptable, He then gets an idea to add and enzyme designed specifically for these two chemicals and then tries the reaction at the modest 65 degrees Celsius again calling this one trial C. 
Question: Given that this enzyme is designed specifically for use with the chemicals in this experiment, will the reaction for trial C be faster or slower than the reaction in trial B?
Output: faster.
Background Paragraph: In the U.S., the majority of electricity is produced by burning coal or other fossil fuels. This causes air pollution, acid rain, and global warming. Fossil fuels are also limited and may eventually run out. Like fossil fuels, radioactive elements are limited. In fact, they are relatively rare, so they could run out sooner rather than later. On the other hand, nuclear fission does not release air pollution or cause the other environmental problems associated with burning fossil fuels. This is the major advantage of using nuclear fission as a source of energy. 
Story: Iran an Iraq are 2 neighbors. Iraq produces its electricity by burning fossil fuels, while Iran uses nuclear fission as its energy source. 
Question: Which country causes more acid rain?
Output: Iraq.
Background Paragraph: The dangers of global warming are being increasingly studied by a wide global consortium of scientists. These scientists are increasingly concerned about the potential long-term effects of global warming on our natural environment and on the planet. Of particular concern is how climate change and global warming caused by anthropogenic, or human-made releases of greenhouse gases, most notably carbon dioxide, can act interactively, and have adverse effects upon the planet, its natural environment and humans' existence. It is clear the planet is warming, and warming rapidly. This is due to the greenhouse effect, which is caused by greenhouse gases, which trap heat inside the Earth's atmosphere because of their more complex molecular structure which allows them to vibrate and in turn trap heat and release it back towards the Earth. This warming is also responsible for the extinction of natural habitats, which in turn leads to a reduction in wildlife population.The most recent report from the Intergovernmental Panel on Climate Change (the group of the leading climate scientists in the world) concluded that the earth will warm anywhere from 2.7 to almost 11 degrees Fahrenheit (1.5 to 6 degrees Celsius) between 1990 and 2100. 
Story: Spain and Italy participated in a global warming global forum this year. it turns out that Spain uses lots of fossil fuel and natural gas for their economy, while Italy relies on ecological alternatives. 
Question: Which country released fewer greenhouse gases into the atmosphere?
Output: Italy.
Background Paragraph: Regions on the Earth's surface (or in its atmosphere) that are high above mean sea level are referred to as high altitude. High altitude is sometimes defined to begin at 2,400 meters (8,000 ft) above sea level.[5][6][7]

At high altitude, atmospheric pressure is lower than that at sea level. This is due to two competing physical effects: gravity, which causes the air to be as close as possible to the ground; and the heat content of the air, which causes the molecules to bounce off each other and expand.[8]. 
Story: There was a competition for who can get their gray drone the highest into the air. Team 20 got it 3,334 ft. Team 21 got it 4,445 ft. Team 22 go it 5,556 ft. Team 23 got it 6,667 ft. Team 24 got it 11,112 ft. Team 25 got it 12,223 ft. Team 26 got it 13,333 ft. 
Question: What team got their drone into high altitude: Team 20 or Team 25?
Output: Team 25.
Background Paragraph: During late adulthood, the risk of developing diseases such as cardiovascular diseases and cancer continues to rise. Most people also have a decline in strength and stamina. Their senses may start failing, and their reflex time typically increases. Their immune system also doesn’t work as well as it used to. As a result, common diseases like the flu may become more serious and even lead to death. The majority of late adults develop arthritis, and as many as one in four develop Alzheimer’s disease. 
Story: Mike is studying the population growth rate of countries around the world. He noticed that countries like Japan and Russia are having a demographic shift. They have a growing population of late adulthood. He recorded the late adulthood population as population A. On the other hand, many developing countries have growing population of younger people. He recorded younger population as population B. 
Question: Which population would less likley develop cardiovascular diseases, population A or population B?
Output: population B.
Background Paragraph: When waves travel into areas of shallow water, they begin to be affected by the ocean bottom. The free orbital motion of the water is disrupted, and water particles in orbital motion no longer return to their original position. As the water becomes shallower, the swell becomes higher and steeper, ultimately assuming the familiar sharp-crested wave shape. After the wave breaks, it becomes a wave of translation and erosion of the ocean bottom intensifies. 
Story: Most surfers used Wide beach because of the areas of shallow water, but some surfers were happy with Sandy beach, although the water was much deeper at the shore there. 
Question: Which beach experiences more disruption of the free orbital motion of the water?
Output: Wide.
Background Paragraph: The quantity of small plastic fragments floating in the north-east Pacific Ocean increased a hundredfold between 1972 and 2012.Marine pollution is a generic term for the harmful entry into the ocean of chemicals or particles. The main culprits are those using the rivers for disposing of their waste. The rivers then empty into the ocean, often also bringing chemicals used as fertilizers in agriculture. The excess of oxygen-depleting chemicals in the water leads to hypoxia and the creation of a dead zone.Marine debris, also known as marine litter, is human-created waste that has ended up floating in a lake, sea, ocean, or waterway. Oceanic debris tends to accumulate at the center of gyres and coastlines, frequently washing aground where it is known as beach litter.In addition, the Pacific Ocean has served as the crash site of satellites, including Mars 96, Fobos-Grunt, and Upper Atmosphere Research Satellite. 
Story: Tim and Joe were two friends living near two different oceans. Tim lived on the Pacific coast while Joe lived on the Atlantic coast. 
Question: Which friend sees less marine pollution?
Output: Joe.
Background Paragraph: Reactions are favorable when they result in a decrease in enthalpy and an increase in entropy of the system. When both of these conditions are met, the reaction occurs naturally. A spontaneous reaction is a reaction that favors the formation of products at the conditions under which the reaction is occurring. A roaring bonfire is an example of a spontaneous reaction, since it is exothermic (there is a decrease in the energy of the system as energy is released to the surroundings as heat). The products of a fire are composed partly of gases such as carbon dioxide and water vapor. The entropy of the system increases during a combustion reaction. The combination of energy decrease and entropy increase dictates that combustion reactions are spontaneous reactions. 
Story: Mike and his family are going on a camping trip. Mike being the outdoors-man he is decides to bring an axe along so they can make an authentic campfire. When they get to the site he chops some wood, piles it up and lights it creating a nice strong flame. 
Question: Which would be considered entropy, the wood being consumed in the fire or the heat of the fire?
Output: fire.
Background Paragraph: Turner et al (2006) derived crash prediction models for this report’s predecessor and found a
pronounced ‘safety in numbers’ effect in the models. Using the crash prediction model for mid-block
locations, generic motorist and cyclist volumes can be used to demonstrate the impacts on the
expected crash rate of varying motor vehicle and cycle volumes. As shown in figure 2.20, an increase
in the proportion of cyclists to the overall traffic volume causes an increase in expected crashes at
mid-block locations, but the crash rate increases at a decreasing rate. That is to say, the crash rate per
cyclist goes down as the cycle volume increases. 
Story: There were a lot of motorcycles on Interstate 15 last week. On Saturday, there were 1551 motorcyclists. On Sunday, there were 2551 motorcyclists. On Monday, there were 3551 motorcyclists. On Tuesday, there were 4551 motorcyclists. On Wednesday, there were 5551 motorcyclists. On Thursday, there were 6551 motorcyclists. On Friday, there were 7551 motorcyclists. 
Question: What day had a lower crash rate per cyclist: Saturday or Friday?
Output: Friday.
