Background Paragraph: In common everyday speech, speed of sound refers to the speed of sound waves in air. However, the speed of sound varies from substance to substance: sound travels most slowly in gases; it travels faster in liquids; and faster still in solids. For example, (as noted above), sound travels at 343 m/s in air; it travels at 1,480 m/s in water (4.3 times as fast as in air); and at 5,120 m/s in iron (about 15 times as fast as in air). In an exceptionally stiff material such as diamond, sound travels at 12,000 metres per second (27,000 mph);[1] (about 35 times as fast as in air) which is around the maximum speed that sound will travel under normal conditions. 
Story: A popular radio station was playing the classic rock songs. There was a radio in a car with a lot of obstacles between the station. There was a fire with a lot of smoke, a river, and a mountain. The man driving the car had a great time listening to the classics. 
Question: Where was the radio signal traveling the fastest: smoke or river?
Output: river.
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 location will be the best one for the Johnson Families' picnic?
Output: Tulsa Valley.
Background Paragraph: Like water in the ocean, air in the atmosphere exerts pressure that increases with depth. Most gas molecules in the atmosphere are pulled close to Earth’s surface by gravity. As a result, air pressure decreases quickly at lower altitudes and then more slowly at higher altitudes. This is illustrated in Figure below . Air pressure is greatest at sea level, where the depth of the atmosphere is greatest. At higher altitudes, the pressure is less because the depth of the atmosphere is less. For example, on top of Mount Everest, the tallest mountain on Earth, air pressure is only about one-third of the pressure at sea level. At such high altitudes, low air pressure makes it hard to breathe and is dangerous to human health. 
Story: There are two neighboring cities, Brampton and Filtroy. The two towns depend on each other by trading supplies and goods regularly. Filtroy is located on top of a very tall mountain, and Brampton is situated at the base of this hill. For this reason, it can sometimes be difficult to traverse the roads to trade goods, but it's important to do it so both cities can thrive. 
Question: Which town most likely has citizens with a lower average lifespan?
Output: Filtroy.
Background Paragraph: Active transport occurs when a substance passes through the cell membrane with the help of extra energy. This happens when a substance moves from an area where it is less concentrated to an area where it is more concentrated. This is the opposite of diffusion. The substance moves up, instead of down, the concentration gradient. Like rolling a ball uphill, this requires an input of energy. The energy comes from the molecule named ATP (adenosine triphosphate). The energy allows special transport proteins called pumps to move substances to areas of higher concentration. An example is the sodium-potassium pump. 
Story: Two cells, Cell B and Cell C, are being examined under microscopes by students in a science class. While looking at the cells, one student, Kim, notices that there is a noticeable trend in Cell B for a particular substance to try to group up in a more concentrated area. In Cell C though, she notices that the same substance is spreading apart and finding less concentrated areas to move to. 
Question: Pumps are being utilized less in which cell?
Output: Cell C.
Background Paragraph: The advantage of asexual reproduction is that it can be very quick and does not require the meeting of a male and female organism. The disadvantage of asexual reproduction is that organisms do not receive a mix of traits from both parents. An organism that is born through asexual reproduction only has the DNA from the one parent. In fact, the offspring is genetically an exact copy of the parent. This can cause problems for the individual. For example, if the parent has a gene that causes a particular disease, the offspring will also have the gene that causes that disease. Organisms produced sexually may or may not inherit the disease gene because they receive a mix of their parents' genes. 
Story: Students studied two groups of organisms. Group A composed of organisms that reproduce sexually, and group B composed of organisms that reproduce asexually. They were fascinated by their discoveries. 
Question: Which group of organisms reproduces slower?
Output: Group A.
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 but used arthropods for food. 
Question: Which village used minilivestocks for human food?
Output: Tree.
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 16 last week. On Sunday, there were 1255 motorcyclists. On Monday, there were 2255 motorcyclists. On Tuesday, there were 3251 motorcyclists. On Wednesday, there were 4251 motorcyclists. On Thursday, there were 5251 motorcyclists. On Friday, there were 6251 motorcyclists. On Saturday, there were 7251 motorcyclists. 
Question: What day had a lower crash rate per cyclist: Tuesday or Friday?
Output: Friday.
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: Factories around the world produce lots of CFCs which deplete the ozone layer. One year a large number of these factories decided they would implement efforts to reduce the amount of CFCs they release into the atmosphere. As a result the depletion of the ozone layer greatly decreased. However, the companies realized that this was hurting profits too much and reverted their decision. As a result the ozone layer began to rapidly deplete again. 
Question: Given the ozone layer starts to deplete much faster than before, has the amount of CFCs released into the atmosphere increased or decreased?
Output: increased.
Background Paragraph: The epidermis also contains melanocytes , which are cells that produce melanin. Melanin is the brownish pigment that gives skin much of its color. Everyone has about the same number of melanocytes, but the melanocytes of people with darker skin produce more melanin. The amount of melanin produced is determined by heredity and exposure to UV light, which increases melanin output. Exposure to UV light also stimulates the skin to produce vitamin D . Because melanin blocks UV light from penetrating the skin, people with darker skin may be at greater risk of vitamin D deficiency. 
Story: John is learning more about different cultures and people around the world. He noticed that people have different skin colors. To learn more about the science behind skin colors he categorized the skin colors into two broad groups, case D and case L. Case D is represented by darker skin and case L is represented by lighter skin. 
Question: People in which case would have greater risk of vitamin D deficiency, case D or case L?
Output: case D.
Background Paragraph: Scientists think that the earliest flowers attracted insects and other animals, which spread pollen from flower to flower. This greatly increased the efficiency of fertilization over wind-spread pollen, which might or might not actually land on another flower. To take better advantage of this “animal labor,” plants evolved traits such as brightly colored petals to attract pollinators. In exchange for pollination, flowers gave the pollinators nectar. 
Story: Last week, John visited the national park near his city. He saw many flowers. His guide explained him that there are two categories of flowers, category A and category B. Category A flowers spread pollen via wind, and category B flowers spread pollen via animals. 
Question: Which flower would have more colorful petals, category A or category B?
Output: category B.
Background Paragraph: For most substances, when the temperature of the solid is raised high enough, the substance changes to a liquid, and when the temperature of the liquid is raised high enough, the substance changes to a gas. We typically visualize a solid as tiny particles in constant motion held together by attractive forces. As we add heat to the solid, the motion, or the kinetic energy, of the particles increases. At some temperature, the motion of the particles becomes great enough to overcome the attractive forces. The thermal energy that was added to the solid up to this point was absorbed by the solid as kinetic energy, increasing the speed of the molecules. The lowest temperature at which the particles are able to exist in the liquid form is called the melting point . 
Story: As a science experiment for his school homework, Kendra is putting two ice cubes on separate pans and then putting those pans on burners set to different temperatures. Ice cube A is set on top of a burner set to a low temperature, and ice cube B is placed on a burner set quite a bite higher. One minute later, Kendra begins writing down what she sees happening to the ice cubes. 
Question: Which ice cube will melt faster?
Output: ice cube B.
Background Paragraph: Research has shown an inverse link between income inequality and social cohesion. In more equal societies, people are much more likely to trust each other, measures of social capital (the benefits of goodwill, fellowship, mutual sympathy and social connectedness among groups who make up a social units) suggest greater community involvement, and homicide rates are consistently lower. 
Story: Ron, a sociologist, traveled to two very different societies, society A and society B, for several months each and wrote down his observations. Ron is now examining the data he gathered from the two societies in an attempt to draw scientific conclusions, and write up a paper. In society A, he found that there were high levels of income inequality, while society B had low levels of income inequality. 
Question: Will society B have higher or lower rates of homicide compared to society A?
Output: lower.
Background Paragraph: Alpine tundra occurs at high enough altitude at any latitude. Portions of montane grasslands and shrublands ecoregions worldwide include alpine tundra. Large regions of alpine tundra occur in the North American Cordillera, the Alps and Pyrenees of Europe, the Himalaya and Karakoram of Asia, the Andes of South America, and the Eastern Rift mountains of Africa.Alpine tundra occupies high-mountain summits, slopes, and ridges above timberline. Aspect plays a role as well; the treeline often occurs at higher elevations on warmer equator-facing slopes. Because the alpine zone is present only on mountains, much of the landscape is rugged and broken, with rocky, snowcapped peaks, cliffs, and talus slopes, but also contains areas of gently rolling to almost flat topography.Averaging over many locations and local microclimates, the treeline rises 75 metres (245 ft) when moving 1 degree south from 70 to 50°N, and 130 metres (430 ft) per degree from 50 to 30°N. Between 30°N and 20°S, the treeline is roughly constant, between 3,500 and 4,000 metres (11,500 and 13,100 ft). 
Story: Pete and Laura were learning about Earth's vegetation. Laura read about savannas and subtropical vegetation, while Pete read about alpine tundras. 
Question: Which person read more about the Pyrenees of Europe?
Output: Pete.
Background Paragraph: Light may transfer its energy to matter rather than being reflected or transmitted by matter. This is called absorption . When light is absorbed, the added energy increases the temperature of matter. If you get into a car that has been sitting in the sun all day, the seats and other parts of the car’s interior may be almost too hot to touch, especially if they are black or very dark in color. That’s because dark colors absorb most of the sunlight that strikes them. 
Story: Marcus is going for a walk outside. He is wearing a black shirt and notices it feels very hot to him. His friend Adam joins him shortly after. Adam is wearing a white shirt and expressed to Adam how nice it is outside. He doesn't feel nearly as hot as Marcus. 
Question: Will a car painted white absorb more or less energy from light than a black painted car?
Output: less.
Background Paragraph: Candied fruit, also known as crystallized fruit or glacé fruit, has existed since the 14th century. Whole fruit, smaller pieces of fruit, or pieces of peel, are placed in heated sugar syrup, which absorbs the moisture from within the fruit and eventually preserves it. Depending on size and type of fruit, this process of preservation can take from several days to several months.[1] This process allows the fruit to retain its quality for a year.[2]

The continual process of drenching the fruit in syrup causes the fruit to become saturated with sugar, preventing the growth of spoilage microorganisms due to the unfavourable osmotic pressure this creates.[3]. 
Story: Dan decided to preserve some fruit and roots to see how long they last before they spoil. He also bought other fruit that he plans to eat fresh. He candied plums, pears, ginger and quince, and he ate fresh apples, oranges and mango. 
Question: Which fruit have a lower sugar content candied plums or fresh apples?
Output: fresh apples.
Background Paragraph: One result of air pollution is acid rain. Acid rain is precipitation with a low (acidic) pH. This rain can be very destructive to wildlife. When acid rain falls in forests, freshwater habitats, or soils, it can kill insects and aquatic life. It causes this damage because of its very low pH. Sulfur oxides and nitrogen oxides in the air both cause acid rain to form ( Figure below ). Sulfur oxides are chemicals that are released from coal-fired power plants. Nitrogen oxides are released from motor vehicle exhaust. 
Story: Italy and Greece attended the World Ecological Conference. they were looking for solutions to improve their environment. Italy's air was very polluted, while Greece had problems with drought. 
Question: Which country had less acid precipitation fall in freshwater habitats?
Output: Greece.
Background Paragraph: Sand mining is a direct cause of erosion, and impacts the local wildlife.[2] Various animals depend on sandy beaches for nesting clutches, and mining has led to the near extinction of gharials (a species of crocodile) in India. Disturbance of underwater and coastal sand causes turbidity in the water, which is harmful for organisms like coral that need sunlight. It can also destroy fisheries, financially harming their operators.

Removal of physical coastal barriers, such as dunes, sometimes leads to flooding of beachside communities, and the destruction of picturesque beaches causes tourism to dissipate. Sand mining is regulated by law in many places, but is often done illegally.[3] Globally, it is a $70 billion industry, with sand selling at up to $90 per cubic yard.[4]. 
Story: Sand mining in the north coastal region was stopped 20 years ago, but it still continues to this day in the south region. Both fishing communities there are still prosperous, but the southern one had a couple of bad years, with fish and other marine wildlife becoming more scarce. The southern beach had erosion problems as well. The northern beach recovered, and is suitable for tourism. 
Question: Which region has a lower water turbidity?
Output: northern.
Background Paragraph: Hepatitis B is a contagious virus that affects the liver, infection can last from a few weeks to a serious lifelong illness. Two different types of infection exist for this disease, "acute" and "chronic." Acute Hepatitis B is a short term illness that occurs within 6 months of exposure, Chronic Hepatitis B is long term and happens when the virus remains in the body. The younger the child is, the greater their chance of developing a chronic infection and this risk goes down as the child gets older. Approximately 90% of infected infants will develop a chronic infection.[3]. 
Story: A 4th grade classroom photo was held today. They all gathered by age. Anthony was the youngest. Kevin was the 2nd youngest. Jason was the 3rd youngest. Matthew was the 4th youngest. Gary was the 5th youngest. Timothy was the 6th youngest. The last one was Jose, who was the oldest. They all looked fantastic that day. 
Question: Who has a greater chance of developing a chronic infection: Timothy or Anthony?
Output: Anthony.
Background Paragraph: Biodiversity is determined by many things, and one of them is abiotic stress. If an environment is highly stressful, biodiversity tends to be low. If abiotic stress does not have a strong presence in an area, the biodiversity will be much higher.This idea leads into the understanding of how abiotic stress and endangered species are related. It has been observed through a variety of environments that as the level of abiotic stress increases, the number of species decreases. This means that species are more likely to become population threatened, endangered, and even extinct, when and where abiotic stress is especially harsh. 
Story: Two neighboring regions were exposed to different levels of abiotic stress. Eastern region was exposed to high levels of abiotic stress, while Western region was almost stress-free. 
Question: Which region had more species go extinct?
Output: Eastern.
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 yellow drone the highest into the air. Team A got it 2,551 ft. Team B got it 3,551 ft. Team C go it 4,541 ft. Team D got it 5,531 ft. Team E got it 10,521 ft. Team F got it 13,571 ft. Team G got it 14,581 ft. Team G won the contest and got a big gold trophy as the prize. 
Question: What team got their drone into high altitude: Team B or Team F?
Output: Team F.
Background Paragraph: A comet tail—and coma—are features visible in comets when they are illuminated by the Sun and may become visible from Earth when a comet passes through the inner Solar System. As a comet approaches the inner Solar System, solar radiation causes the volatile materials within the comet to vaporize and stream out of the nucleus, carrying dust away with them. Separate tails are formed of dust and gases, becoming visible through different phenomena; the dust reflects sunlight directly and the gases glow from ionisation. Most comets are too faint to be visible without the aid of a telescope, but a few each decade become bright enough to be visible to the naked eye. 
Story: This year thee comets would be of interest, comet A, comet B, and comet C. Comet A and comet B would enter the inner solar system. But comet C would not enter the inner solar system. Moreover, comet A is categorized as a bright comet, but comet B is categorized as a faint comet. 
Question: Which comet's dust would not reflect sunlight, comet A or comet C?
Output: comet C.
Background Paragraph: A person with a serious brain injury usually suffers permanent brain damage. These brain injuries usually occur when an external mechanical force, such as a violent blow or jolt to the head or body, causes brain dysfunction. An object penetrating the skull, such as a bullet or a shattered piece of the skull, also can cause traumatic brain injury. As a result, the person may have trouble talking or controlling body movements. Symptoms depend on what part of the brain was injured. Serious brain injuries can also cause personality changes and problems with mental abilities such as memory. Medicines, counseling, and other treatments may help people with serious brain injuries recover from, or at least learn to cope with, their disabilities. 
Story: Jill and Bob are working on a construction site together when suddenly two wooden planks fall from three stories up. One plank hits Bob on the head and the other lands directly on Jill's shoulder. Everyone rushes over to them to check if they are ok. All the people are relieved that Bob and Jill appear to be alright, but they urge them both to go visit a doctor to get checked out. 
Question: Which person is more likely to have trouble talking?
Output: Bob.
Background Paragraph: Cancer is a disease that causes cells to divide out of control. Normally, the body has systems that prevent cells from dividing out of control. But in the case of cancer, these systems fail. Cancer is usually caused by mutations. Mutations are random errors in genes. Mutations that lead to cancer usually happen to genes that control the cell cycle. Because of the mutations, abnormal cells divide uncontrollably. This often leads to the development of a tumor. A tumor is a mass of abnormal tissue. As a tumor grows, it may harm normal tissues around it. Anything that can cause cancer is called a carcinogen . Carcinogens may be pathogens, chemicals, or radiation. 
Story: A large amount of radioactive waste was found near the town of Arrester. An unusual number of people in Arrester have cancer. In a town 100 miles north of Arrester named Ajani very few people have cancer. There is no radioactive waste near the town of Ajani. 
Question: Which town should you move to if you do not want to increase your chances of developing cancer?
Output: Ajani.
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 20 lb drone the highest into the air. Team 50 got it 3,337 ft. Team 51 got it 4,448 ft. Team 52 go it 5,559 ft. Team 53 got it 6,660 ft. Team 54 got it 11,115 ft. Team 55 got it 12,226 ft. Team 56 got it 13,336 ft. 
Question: What team got their drone into high altitude: Team 51 or Team 54?
Output: Team 54.
Background Paragraph: Biodiversity loss is the extinction of species (plant or animal) worldwide, and also the local reduction or loss of species in a certain habitat.

The latter phenomenon can be temporary or permanent, depending on whether the environmental degradation that leads to the loss is reversible through ecological restoration / ecological resilience or effectively permanent (e.g. through land loss). Global extinction has so far been proven to be irreversible.

Even though permanent global species loss is a more dramatic phenomenon than regional changes in species composition, even minor changes from a healthy stable state can have dramatic influence on the food web and the food chain insofar as reductions in only one species can adversely affect the entire chain (coextinction), leading to an overall reduction in biodiversity, possible alternative stable states of an ecosystem notwithstanding. Ecological effects of biodiversity are usually counteracted by its loss. Reduced biodiversity in particular leads to reduced ecosystem services and eventually poses an immediate danger for food security, also for humankind.[1]. 
Story: Two neighboring lands experienced different climates. In Iceland, the actions of its people lead to a loss of animal and plant species. Denmark tried to keep the environment untouched as they understood its importance and the climate was unaffected. 
Question: Which country experienced a more reduced biological diversity?
Output: Iceland.
Background Paragraph: For an inclined plane, the input distance is the length of the sloping surface, and the output distance is the maximum height of the inclined plane. This was illustrated in Figure above . Because the sloping surface is always greater than the height of the inclined plane, the ideal mechanical advantage of an inclined plane is always greater than 1. An inclined plane with a longer sloping surface relative to its height has a gentler slope. An inclined plane with a gentler slope has a greater mechanical advantage and requires less input force to move an object to a higher elevation. 
Story: John works as a mechanical engineer in the auto industry. He is testing three surfaces, surface A, surface B, and surface C for their usability. Surface A has a gentler slope, surface B has a steeper slope, and surface C doesn't have any sloping. He needs to figure out advantages and disadvantages of each slope. 
Question: Which surface would need less input force to move an object upward, surface A or surface B?
Output: surface A.
Background Paragraph: Soon after the original study was published, other researchers tried to replicate the research. However, it could not be replicated. No other studies could find a link between the vaccine and autism. As a result, scientists became convinced that the original results were incorrect. Eventually, investigators determined that the original study was a fraud. They learned that its author had received a large amount of money to find evidence that the vaccine causes autism, so he faked his research results. If other scientists had not tried to replicate the research, the truth might never have come out. You can read more about this case at the URL below. 
Story: John works for the NSF. He has two research proposals in front of him, case A and case B. Both are looking for further funding. Case A research has been replicated by other researchers, but case B research could not be replicated by others. He needs to decide which research should get further funding. 
Question: In case A, did the scientist more likely of less likely commit a fraud than the scientist in case B?
Output: less likely.
Background Paragraph: The Gaia hypothesis states that the biosphere is its own living organism. The hypothesis suggests that the Earth is self-regulating and tends to achieve a stable state, known as homeostasis . For example the composition of our atmosphere stays fairly consistent, providing the ideal conditions for life. When carbon dioxide levels increase in the atmosphere, plants grow more quickly. As their growth continues, they remove more carbon dioxide from the atmosphere. In this way, the amount of carbon dioxide stays fairly constant without human intervention. 
Story: A scientist with an interesting idea for an experiment begins building a dome. This dome will be completely cut off from the rest of the world. It will produce all of its own resources, breathable air, anything needed to sustain life, putting it into a state of homeostasis. 
Question: Given The Gaia hypothesis, would this dome be considered a living organism or non-living?
Output: living.
Background Paragraph: Rain dissolves fertilizer in the soil. Runoff carries it away. The fertilizer ends up in bodies of water, from ponds to oceans. Nitrogen is a fertilizer in the water. Since there is a lot of nitrogen, it causes algae to grow out of control. Pictured below is a pond covered with algae ( Figure below ). Algae use up carbon dioxide in the water. After the algae die, decomposers break down the dead tissue. The decomposers use up all the oxygen in the water. This creates a dead zone. A dead zone is an area in a body of water where nothing grows because there is too little oxygen. There is a large dead zone in the Gulf of Mexico ( Figure below ). The U.S. states outlined on the map have rivers that drain into the Gulf of Mexico. The rivers drain vast agricultural lands. The water carries fertilizer from these areas into the Gulf. 
Story: Two farms had different plant cultivation methods. Jolly farm adopted the permaculture methods created by Sepp Holzer, while Peach farm continued using fertilizers and pesticides. 
Question: Which farm caused more Nitrogen to end up in oceans?
Output: Peach.
Background Paragraph: Unfortunately, the layer of good ozone is being destroyed by air pollution. The chief culprits are chlorine and bromine gases. They are released in aerosol sprays, coolants, and other products. Loss of ozone has created an ozone hole over Antarctica. Ozone depletion results in higher levels of UV radiation reaching Earth. In humans, this increases skin cancers and eye cataracts. It also disturbs the nitrogen cycle, kills plankton, and disrupts ocean food webs. The total loss of the ozone layer would be devastating to most life. Its rate of loss has slowed with restrictions on pollutants, but it is still at risk. 
Story: Two researchers studied air quality over the North Pole, and over Antarctica. Dan was more fond of the south pole, so he studied Antarctica, while Colt liked reading about the North Pole. 
Question: Which researcher learned less about aerosol sprays?
Output: Colt.
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: An alien passing by Earth in a UFO to write a report on two random cities so that his government can better understand what the people of Earth are like. He first flies over Nillmar, a city in France, which uses burns coal as its main production of electricity. After observing Nillmar, the alien flies over to Springfield, a city in the United States, that decided to use nuclear power to fuel itself. After taking his notes, the alien leaves and is eager to report back to his superiors about what he discovered. 
Question: Which city will need to change its method of electricity production sooner?
Output: Springfield.
Background Paragraph: A few insects, such as mayflies and some moths, never eat. That’s because their lives are over in just a few hours or days. Once these insects become adults, they lay eggs, and then die. On the other hand, some insects are very healthy eaters. A silkworm eats enough leaves to increase its weight more than 4,000 times in just 56 days, as the silkworm increases in size about 10,000 times since birth. A locust eats its own weight in plants every day. Just imagine eating your own weight in food every day. You probably couldn't. You would most likely get very sick even if you tried. 
Story: Billy has decided to start collecting insects. He wants to build a vibrant collection, has a bunch of different bug boxes to store them in. So far he has captured some mayflies, and some locusts. He is trying to decide how to take care of them. 
Question: Will the mayflies live longer or shorter lives than the locusts?
Output: shorter.
Background Paragraph: Hepatitis viruses can develop into a chronic viral infection that leads to liver cancer. Infection by human T-lymphotropic virus can lead to tropical spastic paraparesis and adult T-cell leukaemia. Human papillomaviruses are an established cause of cancers of cervix, skin, anus, and penis. Within the Herpesviridae, Kaposi's sarcoma-associated herpesvirus causes Kaposi's sarcoma and body-cavity lymphoma, and Epstein–Barr virus causes Burkitt's lymphoma, Hodgkin's lymphoma, B lymphoproliferative disorder, and nasopharyngeal carcinoma. Merkel cell polyomavirus closely related to SV40 and mouse polyomaviruses that have been used as animal models for cancer viruses for over 50 years. 
Story: The Jones family had a history of chronic viral infections. Jenny got human papillomavirus, while her brother Josh got infected with the Epstein–Barr virus. They were both under treatment. 
Question: Which sibling had a higher risk of developing Hodgkin's lymphoma?
Output: Josh.
Background Paragraph: Like water in the ocean, air in the atmosphere exerts pressure that increases with depth. Most gas molecules in the atmosphere are pulled close to Earth’s surface by gravity. As a result, air pressure decreases quickly at lower altitudes and then more slowly at higher altitudes. This is illustrated in Figure below . Air pressure is greatest at sea level, where the depth of the atmosphere is greatest. At higher altitudes, the pressure is less because the depth of the atmosphere is less. For example, on top of Mount Everest, the tallest mountain on Earth, air pressure is only about one-third of the pressure at sea level. At such high altitudes, low air pressure makes it hard to breathe and is dangerous to human health. 
Story: There are two neighboring cities, Brampton and Filtroy. The two towns depend on each other by trading supplies and goods regularly. Filtroy is located on top of a very tall mountain, and Brampton is situated at the base of this hill. For this reason, it can sometimes be difficult to traverse the roads to trade goods, but it's important to do it so both cities can thrive. 
Question: In which city is it easier for citizens to breathe?
Output: Brampton.
Background Paragraph: Human beings invented agriculture about 10,000 years ago. This provided a bigger, more dependable food supply. It also allowed people to settle down in villages and cities for the first time. Birth rates went up because there was more food and settled life had other advantages. Death rates also rose because of crowded living conditions and diseases that spread from domestic animals. Because the higher birth rates were matched by higher death rates, the human population continued to grow very slowly. 
Story: David was studying human history. He selected two specific eras of human history, era A and era B. Era A was before humans had invented agriculture. And, era B was after the invention of agriculture. He noticed that human societies had changed dramatically after the invention of agriculture. 
Question: Which era saw lower death rate, era A or era B?
Output: era A.
Background Paragraph: Using longitudinal data from over 100 countries, Diener and his colleagues showed that rich countries are in general happier than poor countries (Diener, Tay, & Oishi, 2013).[17] Also, life satisfaction for most countries goes up as they become wealthier over time. Diener identified three factors that influence the relationship between income and SWB. Namely, rising income most likely results in higher SWB when it leads to greater optimism, financial satisfaction and household material prosperity among citizens. Furthermore, Diener and his colleagues investigated the relationship between income and different elements of SWB. They illustrated that income has stronger influence on people’s evaluation of their lives than the positive or negative emotions they experience over time (Diener, Kahneman, Tov, & Arora, 2010).[18] The study points to the necessity to evaluate different elements of SWB separately instead of treating happiness as a single entity. 
Story: Two neighboring countries implemented different sets of economic reforms. The reforms took over a decade to implement, but the effects were not similar at all. Redvania was more prosperous and it became much richer, while Blueland stagflated and the inhabitants were not pleased with the outcome. 
Question: Which country experienced more stagflation after 10 years?
Output: Blueland.
Background Paragraph: Candied fruit, also known as crystallized fruit or glacé fruit, has existed since the 14th century. Whole fruit, smaller pieces of fruit, or pieces of peel, are placed in heated sugar syrup, which absorbs the moisture from within the fruit and eventually preserves it. Depending on size and type of fruit, this process of preservation can take from several days to several months.[1] This process allows the fruit to retain its quality for a year.[2]

The continual process of drenching the fruit in syrup causes the fruit to become saturated with sugar, preventing the growth of spoilage microorganisms due to the unfavourable osmotic pressure this creates.[3]. 
Story: Mary and Ann got some fruit as a gift from a friend. Mary decided to candy the fruit, while Ann decided to eat them fresh, Mary received plums, peaches, apples and oranges. Ann got pears, quince, cherries and blackberries. 
Question: Which fruit retained their quality longer plums or quince?
Output: plums.
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 16 last week. On Sunday, there were 1255 motorcyclists. On Monday, there were 2255 motorcyclists. On Tuesday, there were 3251 motorcyclists. On Wednesday, there were 4251 motorcyclists. On Thursday, there were 5251 motorcyclists. On Friday, there were 6251 motorcyclists. On Saturday, there were 7251 motorcyclists. 
Question: What day had a lower crash rate per cyclist: Wednesday or Saturday?
Output: Saturday.
Background Paragraph: The lungs of mammals are unique in having alveoli . These are tiny, sac-like structures. Each alveolus is surrounded by a network of very small blood vessels (see Figure below ). Because there are millions of alveoli in each lung, they greatly increase the surface area for gas exchange between the lungs and bloodstream. Human lungs, for example, contain about 300 million alveoli. They give the lungs a total surface area for gas exchange of up to 90 square meters (968 square feet). That’s about as much surface area as one side of a volleyball court!. 
Story: Two groups of students studied Biology. Group One studied mammals, while Group Two studied birds. They focused on the respiratory system. 
Question: Which group of students learned less about human lungs?
Output: Two.
Background Paragraph: Rain dissolves fertilizer in the soil. Runoff carries it away. The fertilizer ends up in bodies of water, from ponds to oceans. The nitrogen is a fertilizer in the water bodies. Since there is a lot of nitrogen it causes algae to grow out of control. Figure below shows a pond covered with algae. Algae may use up so much oxygen in the water that nothing else can grow. Soon, even the algae die out. Decomposers break down the dead tissue and use up all the oxygen in the water. This creates a dead zone. A dead zone is an area in a body of water where nothing grows because there is too little oxygen. There is a large dead zone in the Gulf of Mexico. You can see it Figure below . 
Story: Our family was going to go fishing on Saturday. A few years ago we went fishing down the hill from a mushroom farm called Happy Pond. Since that time, there has been a lot of rain and we noticed Happy Pond had a green coating across the top of it. We also thought about going to a new pond in center of the park called Ridge Pond. We are hoping to catch a lot of fish to serve at our family reunion. 
Question: Which pond has more algae growing on it, Ridge Pond or Happy Pond?
Output: Happy Pond.
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: Jessica and Milly are two politicians currently in the running for governor of their city. They are in the process of having a debate that is being broadcast on local television. Mike, an avid environmentalist who is trying to decide who to vote for, has been watching the entire debate. He feels the most important issue when voting is saving the planet and the animals on it. The question that was just asked by the moderator was "what do you think should be done with the Earth's atmosphere?" Jessica responds that she thinks we should emit more anthropogenic gases. She believes that will lead to the best outcome for the world. Milly states that we need to decrease the amount of carbon dioxide and other gases in the atmosphere. 
Question: Will Jessica's plan lead to an increase or decrease in Earth's temperature?
Output: increase.
Background Paragraph: Sometimes muscles and tendons get injured when a person starts doing an activity before they have warmed up properly. A warm up is a slow increase in the intensity of a physical activity that prepares muscles for an activity. Warming up increases the blood flow to the muscles and increases the heart rate. Warmed-up muscles and tendons are less likely to get injured. For example, before running or playing soccer, a person might jog slowly to warm muscles and increase their heart rate. Even elite athletes need to warm up ( Figure below ). 
Story: Tom and Jim go running together once a week. This week Jim skipped his warm up before exercising, because he was a bit late. Tom warmed up properly before running. 
Question: Which runner has a higher chance of getting a muscle injury?
Output: Jim.
Background Paragraph: Look at the police car in Figure below . The sound waves from its siren travel outward in all directions. Because the car is racing forward (toward the right), the sound waves get bunched up in front of the car and spread out behind it. As the car approaches the person on the right (position B), the sound waves get closer and closer together. In other words, they have a higher frequency. This makes the siren sound higher in pitch. After the car speeds by the person on the left (position A), the sound waves get more and more spread out, so they have a lower frequency. This makes the siren sound lower in pitch. A change in the frequency of sound waves, relative to a stationary listener, when the source of the sound waves is moving is called the Doppler effect . You’ve probably experienced the Doppler effect yourself. The next time a vehicle with a siren races by, listen for the change in pitch. For an online animation of the Doppler effect, go to the URL below. 
Story: A scientist is analyzing two different sounds, one from a deer and one from a zebra, with a device that allows her to see the sound waves of each noise. While looking at the results, she sees that the sound waves for the deer are more closely packed together, but the zebra's sound has very spread out waves. 
Question: Which animal's sound has a higher pitch?
Output: deer.
Background Paragraph: Astronomy is very sensitive to light pollution. The night sky viewed from a city bears no resemblance to what can be seen from dark skies.[78] Skyglow (the scattering of light in the atmosphere at night) reduces the contrast between stars and galaxies and the sky itself, making it much harder to see fainter objects. This is one factor that has caused newer telescopes to be built in increasingly remote areas. 
Story: Whenever Bill visited Tim's house, they couldn't see that many stars when stargazing . Tim lived in the city. The sky was much clearer at night at Bill's place, because he lived in a rural area. 
Question: Where do they have the capability to see many faint objects, at Tim's or at Bill's?
Output: at Bill's.
