Background Paragraph: Geologists study earthquake waves to “see” Earth's interior. Waves of energy radiate out from an earthquake’s focus. These waves are called seismic waves ( Figure below ). Seismic waves go different speeds through different materials. They change speed when they go from one type of material to another. This causes them to bend. Some seismic waves do not travel through liquids or gases. They just stop. Scientists use information from seismic waves to understand what makes up the Earth’s interior. 
Story: Two friends met after 20 years and had a beer together. Vlad was a geologist and studied earthquakes. Mort was a pedologist and studied soils. They had some interesting conversations that night. 
Question: Which friend studied more about earthquake waves?
Output: Vlad.
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 lands applied different economical measures over the last decade. Greenland increased productivity so they became wealthy and prosperous. Iceland chose to increase taxation and expand its government, they had little money to invest. 
Question: Which country had a lower productivity?
Output: Iceland.
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 more acid precipitation fall on soils?
Output: Italy.
Background Paragraph: In exercises such as weight lifting, skeletal muscle contracts against a resisting force (see Figure below ). Using skeletal muscle in this way increases its size and strength. In exercises such as running, the cardiac muscle contracts faster and the heart pumps more blood. Using cardiac muscle in this way increases its strength and efficiency. Continued exercise is necessary to maintain bigger, stronger muscles. If you don’t use a muscle, it will get smaller and weaker—so use it or lose it. 
Story: Justin and Derek are accomplished competitive weight lifters. One day, Derek suffers a severe injury to his leg. Because of this injury, Derek is forced to stop exercising for several months. Justin remains injury free and continues to work out regularly on the other hand. 
Question: Who will lose less size on their muscles?
Output: Justin.
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: David was visiting the natural history museum. He noticed two charts that showed the climatic conditions of the earth in two time periods, time A and time B. Time A showed earth's overall climate in the sixteenth century when there were less greenhouse gases in the atmosphere. And time B showed earth's overall climate in the present century with more greenhouse gases in the atmosphere. David found some interesting differences between these two charts. 
Question: Which period would see less trapped terrestrial radiation, time A or time B?
Output: time A.
Background Paragraph: Gasoline-powered vehicles emit a lot of harmful materials. Nitrogen oxides are formed when atmospheric nitrogen reacts with oxygen at the high temperatures found in a car engine. Carbon monoxide is a by-product of incomplete combustion of hydrocarbons. Evaporated and unused fuel releases volatile hydrocarbons into the atmosphere to help form smog. The presence of a catalytic converter in the exhaust system of the car causes these materials to react and be changed into less harmful products. 
Story: Blue island and Red island were two big sister islands situated 100 miles from each other. People on Blue island used gas powered vehicles, while people on Red island used electrical vehicles. The people on Blue island presented more respiratory problems. 
Question: Which island emitted fewer harmful materials?
Output: Red.
Background Paragraph: Hemophilia is the name of a group of hereditary diseases that affect the body's ability to control blood clotting. Hemophilia is caused by a lack of clotting factors in the blood. Clotting factors are normally released by platelets. Since people with hemophilia cannot produce clots, any cut can put a person at risk of bleeding to death. The risk of internal bleeding is also increased in hemophilia, especially into muscles and joints. This disease affected the royal families of Europe. 
Story: Two twin sisters were taken to the doctor's office by their parents. It turned out that Mary had hemophilia while Ann didn't have any blood disease. 
Question: Which sister had blood that didn't clot?
Output: Mary.
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: Bob was studying about Earth's atmosphere. He found that increased depletion of Earth's ozone layer is a relatively new phenomenon. Most scientists would blame the CFC gases for the depletion of ozone layer. In the early twentieth century ozone layer was relatively stable. Bob labeled that time as time A. But in the late twentieth century situation changed with seasonal depletion of ozone layer. He labeled that time as time B. 
Question: In which time more fish DNA would be damaged, time A or time B?
Output: time B.
Background Paragraph: Another thing we can see in this animation is that particles are constantly colliding with one another. One assumption that we make when talking about collisions between gas particles is that they are completely elastic collisions. In an elastic collision , momentum is conserved, which means that none of the kinetic energy of the colliding particles is lost in some other form (such as the emission of light). This makes sense, because if energy were lost in collisions, the speeds of the particles would gradually decrease over time, and eventually everything would condense down into a solid form. 
Story: Dan is in his physics lab. He is experimenting with colliding particles. He has two samples of particles, sample A and sample B. Sample A contains gas particles, but sample B does not contain gas particles. 
Question: Which sample's kinetic energy likely be retained, sample A or sample B?
Output: sample A.
Background Paragraph: East Antarctica is colder than its western counterpart because of its higher elevation. Weather fronts rarely penetrate far into the continent, leaving the centre cold and dry. Despite the lack of precipitation over the central portion of the continent, ice there lasts for extended periods. Heavy snowfalls are common on the coastal portion of the continent, where snowfalls of up to 1.22 metres (48 in) in 48 hours have been recorded. 
Story: Two teams of scientists were in Antarctica to study the weather. Camp Alpha was located in East Antarctica, while camp Omega was situated in West Antarctica. 
Question: Which camp observed that ice there lasts for extended periods?
Output: Alpha.
Background Paragraph: Saturated hydrocarbons are given the general name of alkanes . The name of specific alkanes always ends in - ane . The first part of the name indicates how many carbon atoms each molecule of the alkane has. The smallest alkane is methane. It has just one carbon atom. The next largest is ethane, with two carbon atoms. The chemical formulas and properties of methane, ethane, and several other alkanes are listed in Table below . The boiling and melting points of alkanes are determined mainly by the number of carbon atoms they have. Alkanes with more carbon atoms generally have higher boiling and melting points. 
Story: Ian is learning about alkanes in science class and their melting and boiling points. He is given a few different alkanes try try with this test, mainly methane ethane and a third alkane that he has to test to find out what it is called Alkane C. 
Question: Which prefix means 2 carbom atoms when refering to alkanes, meth or eth?
Output: eth.
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 didn't read about antiretroviral drugs?
Output: George.
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 the surface area for gas exchange between the lungs and bloodstream?
Output: Two.
Background Paragraph: Alcoholic beverages do not make the entire body warmer.[361] The reason that alcoholic drinks create the sensation of warmth is that they cause blood vessels to dilate and stimulate nerve endings near the surface of the skin with an influx of warm blood. This can actually result in making the core body temperature lower, as it allows for easier heat exchange with a cold external environment. 
Story: Two people got stuck in a local  blizzard. Tom had a bottle of alcohol with him and drank it after he found some kind of shelter in the snow. Dan didn't have alcohol with him. 
Question: Which of the two people had more blood vessels dilate?
Output: Tom.
Background Paragraph: Liquid water is a fluid. The hydrogen bonds in liquid water constantly break and reform as the water molecules tumble past one another. As water cools, its molecular motion slows and the molecules move gradually closer to one another. The density of any liquid increases as its temperature decreases. For most liquids, this continues as the liquid freezes and the solid state is denser than the liquid state. However, water behaves differently. It actually reaches its highest density at about 4°C. 
Story: A waitress sets down two cups of water at a table and then takes the table's order. She leaves to place the order and the diners begin chatting and sipping on their water. Kim remarks that her water is room temperature and she wishes that it was cooler. Janet states that her water is so cold it hurts her teeth and wishes hers was warmer. They agree to mention it to the waitress when she returns. 
Question: Which person's water has molecules moving faster?
Output: Kim.
Background Paragraph: According to current definitions, all planets must revolve around stars; thus, any potential "rogue planets" are excluded. In the Solar System, all the planets orbit the Sun in the same direction as the Sun rotates (counter-clockwise as seen from above the Sun's north pole). At least one extrasolar planet, WASP-17b, has been found to orbit in the opposite direction to its star's rotation. The period of one revolution of a planet's orbit is known as its sidereal period or year. A planet's year depends on its distance from its star; the farther a planet is from its star, not only the longer the distance it must travel, but also the slower its speed, because it is less affected by its star's gravity. No planet's orbit is perfectly circular, and hence the distance of each varies over the course of its year. The closest approach to its star is called its periastron (perihelion in the Solar System), whereas its farthest separation from the star is called its apastron (aphelion). As a planet approaches periastron, its speed increases as it trades gravitational potential energy for kinetic energy, just as a falling object on Earth accelerates as it falls; as the planet reaches apastron, its speed decreases, just as an object thrown upwards on Earth slows down as it reaches the apex of its trajectory.Each planet's orbit is delineated by a set of elements:. 
Story: John is an amateur astronomer. Last week he was observing the sky with his telescope. First he pointed his telescope at planet Mars. He noted it as case A. Then he pointed his telescope to planet Jupiter, which is farther form the Sun than Mars is. He noted it as case C. Finally, he pointed the telescope to a faraway planet called WASP-17b. He noted that as case B. 
Question: Which case would have longer year, case A or case C?
Output: case C.
Background Paragraph: A red giant star is a star with a mass like the Sun that is in the last phase of its life, when Hydrogen fusion reactions in the core decrease due to the lack of fuel. With the gravitational collapse of the core, the fusion reactions now occur in a shell surrounding the core. The outer layer of the star expands enormously up to 1000 times the size of the Sun. When the Sun becomes a red giant, its volume will include the orbit of Mercury and Venus and maybe even Earth. The increased size increases the luminosity even though the outer layer cools to only 3000 K or so. The cooler outer layer causes it to be a red star. After a few more million years, the star evolves into a white dwarf-planetary nebula system. 
Story: Two stars have just been discovered that are identical in terms of chemical composition. The scientist who discovered them was given the right to name them, and he chose the names Enterprise and Vader. As said before, these stars are very similar, but the main difference is that Vader is a red giant, and Enterprise is not. Scientists are very eager to study these two newly discovered stars and see if they can learn anything new from them. 
Question: Does Enterprise have more or less fuel than Vader?
Output: more.
Background Paragraph: Clouds on Earth are made of water vapor. Venus's clouds are a lot less pleasant. They are made of carbon dioxide, sulfur dioxide and large amounts of corrosive sulfuric acid! The atmosphere of Venus is so thick that the pressure on the surface of Venus is very high. In fact, it is 90 times greater than the pressure at Earth’s surface! The thick atmosphere causes a strong greenhouse effect. As a result, Venus is the hottest planet. Even though it is farther from the Sun, Venus is much hotter even than Mercury. Temperatures at the surface reach 465°C (860°F). That’s hot enough to melt lead!. 
Story: Two students were learning about atmospheres and planets. Dan learned about the atmosphere of Earth, while Nate learned about planet Venus and its atmosphere. 
Question: Which student learned less about the planet with a hotter surface temperature?
Output: Dan.
Background Paragraph: Alcoholic beverages do not make the entire body warmer.[361] The reason that alcoholic drinks create the sensation of warmth is that they cause blood vessels to dilate and stimulate nerve endings near the surface of the skin with an influx of warm blood. This can actually result in making the core body temperature lower, as it allows for easier heat exchange with a cold external environment. 
Story: A research institute is investigating the effect of alcohol in human body. They gave two groups of subjects, group blue and group red, two different drinks, labeled as blue drink and red drink. The blue drink contained alcohol, and the red drink did not contain any alcohol. Blue drinks were given to the blue group and the red drinks were given to the red group. 
Question: Would red group have lower of higher core body temperature than blue group?
Output: higher.
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: Two cousins both have chronic viral infections. Tim has Kaposi's sarcoma-associated herpesvirus, while Nate has the Epstein–Barr virus. 
Question: Which cousin has a lower chance of developing Hodgkin's lymphoma?
Output: Tim.

They agree to mention it to the waitress when she returns. 
Question: Which person's water has molecules closer together?
Output: Janet.
Background Paragraph: Windbreaks reduce wind velocity over and around crops. This increases yields through reduced drying of the crop and/or by preventing the crop from toppling in strong wind gusts. 
Story: Two farms had winds destroying their crops. Hill farm started installing windbreaks, while Valley farm didn't have the funds to do that so they postponed the project. 
Question: Which farm prevented the crop from toppling?
Output: Hill.
Background Paragraph: Middle adulthood lasts from the mid-30s to the mid-60s. During this stage of life, many people raise a family and strive to attain career goals. They start showing physical signs of aging, such as wrinkles and gray hair. Typically, vision, strength and reaction time start declining. Diseases such as type 2 diabetes, cardiovascular or heart disease, and cancer are often diagnosed during this stage of life. These diseases are also the chief causes of death in middle adulthood. 
Story: Adam and his older brother Chris were born almost 15 years apart from each other. Adam is 27 now which means Chris is 41.  Lately Chris has started noticing grey hairs come in. When Adam and him play games together Chris also seems to lose more often now even though historically he has always been better. 
Question: Which brother is likely experiencing a decline in strength, Adam or Chris?
Output: Chris.
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 more people with decreased stamina?
Output: group O.
Background Paragraph: In nature, when the population size is small, there is usually plenty of food and other resources for each individual. When there is plenty of food and other resources, organisms can easily reproduce, so the birth rate is high. As the population increases, the food supply, or the supply of another necessary resource, may decrease. When necessary resources, such as food, decrease, some individuals will die. Overall, the population cannot reproduce at the same rate, so the birth rates drop. This will cause the population growth rate to decrease. 
Story: Two neighboring countries of similar size and wealth of resources had different sized population. Deerland had a small population, while Bearland had a large population. Both peoples lived mostly off the land. 
Question: Which country had less food per individual?
Output: Bearland.
Background Paragraph: Fish reproduce sexually. They lay eggs that can be fertilized either inside or outside of the body. In most fish, the eggs develop outside of the mother's body. In the majority of these species, fertilization also takes place outside the mother's body. The male and female fish release their gametes into the surrounding water, where fertilization occurs. Female fish release very high numbers of eggs to increase the chances of fertilization. 
Story: Two brothers learned about animal reproduction, Tim learned about fish reproduction, while Bill learned about mammal reproduction. They both received grade A. 
Question: Which brother studied less about eggs developing outside of the mother's body?
Output: Bill.

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 brothers went on vacation. Tom partied heavily, and found out that he was infected with the HIV virus. Tim was more moderate, he went to the beach to get a sun tan, but he got an infection as well. Tim found out he got a bacterial infection and had to take antibiotics. 
Question: Which brother had a greater chance of developing AIDS?
Output: Tom.
Background Paragraph: During May, June, and July, the Northern Hemisphere is exposed to more direct sunlight because the hemisphere faces the Sun. The same is true of the Southern Hemisphere in November, December, and January. It is Earth's axial tilt that causes the Sun to be higher in the sky during the summer months, which increases the solar flux. However, due to seasonal lag, June, July, and August are the warmest months in the Northern Hemisphere while December, January, and February are the warmest months in the Southern Hemisphere. 
Story: Stan moved from the US to Australia, and he still gets confused because of the seasons in the southern hemisphere and the fact that they use the same calendar as the rest of the world. 
Question: Which month is warmer in the northern hemisphere, June or December?
Output: June.
Background Paragraph: Fish reproduce sexually. They lay eggs that can be fertilized either inside or outside of the body. In most fish, the eggs develop outside of the mother's body. In the majority of these species, fertilization also takes place outside the mother's body. The male and female fish release their gametes into the surrounding water, where fertilization occurs. Female fish release very high numbers of eggs to increase the chances of fertilization. 
Story: All marine creatures are not fish. There are some mammals, for example, whales, also live in the water. Rob wants to know more about differences between fish and other non fish creatures in the water. He divided them into two groups, group A and group B. Group A consists of fish, and group B consists of non fish creatures in the water. He started to see the differences between these two groups. 
Question: In which group the females would most likely release high numbers of eggs, group A or group B?
Output: group A.
Background Paragraph: Depleted soils can be protected from soil erosion by groundcover plants such as naturally growing grasses in agroforestry systems. These help to stabilise the soil as they increase cover compared to short-cycle cropping systems. Soil cover is a crucial factor in preventing erosion. Cleaner water through reduced nutrient and soil surface runoff can be a further advantage of agroforestry. The runoff can be reduced by decreasing its velocity and increasing infiltration into the soil. Compared to row-cropped fields nutrient uptake can be higher and reduce nutrient loss into streams.Further advantages concerning plant growth:. 
Story: Two neighboring farms both had depleted soils due to intensive agricultural practices for decades. Apple far decided to start an agroforestry system and other methods to protect their depleted soils, while Pear farm did nothing and had big losses the following years. 
Question: Which farm didn't reduce the runoff?
Output: Pear.
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 islands of identical size with similar ecosystems experienced different destinies. Caribu island, inhabited by more natives, hunted a few of the animal species there, contributing to the extinction of a few. People from Hiji island, were pescotarian, and hardly ever fished. 
Question: Which islanders ate more meat?
Output: Caribu.
Background Paragraph: Many respiratory diseases are caused by pathogens. A pathogen is an organism that causes disease in another organism. Certain bacteria, viruses, and fungi are pathogens of the respiratory system. The common cold and flu are caused by viruses. The influenza virus that causes the flu is pictured below ( Figure below ). Tuberculosis, whooping cough, and acute bronchitis are caused by bacteria. The pathogens that cause colds, flu, and TB can be passed from person to person by coughing, sneezing, and spitting. Illnesses caused by bacteria can be treated with antibiotics. Those caused by viruses cannot. 
Story: Big city and Large city are situated 50 miles apart, on opposite sides of a mountain range. Both cities have lots of people with respiratory diseases. Big city has more people getting infected by viruses, while Large city has more people infected by bacteria and fungi. 
Question: Which city has fewer people catching the common cold?
Output: Large.
Background Paragraph: The benefits provided by no-tillage to predators may lead to larger predator populations, which is a good way to control pests (biological control), but also can facilitate predation of the crop itself. In corn crops, for instance, predation by caterpillars can be higher in no-till than in conventional tillage fields.In places with rigorous winter, untilled soil can take longer to warm and dry in spring, which may delay planting to less ideal dates. Another factor to be considered is that organic residue from the prior year's crops lying on the surface of untilled fields can provide a favorable environment to pathogens, helping to increase the risk of transmitting diseases to the future crop. And because no-till farming provides good environment for pathogens, insects and weeds, it can lead farmers to a more intensive use of chemicals for pest control. Other disadvantages of no-till include underground rot, low soil temperatures and high moisture.Based on the balance of these factors, and because each farm has different problems, agroecologists will not attest that only no-till or complete tillage is the right way of farming. Yet, these are not the only possible choices regarding soil preparation, since there are intermediate practices such as strip-till, mulch-till and ridge-till, all of them – just as no-till – categorized as conservation tillage. Agroecologists, then, will evaluate the need of different practices for the contexts in which each farm is inserted. 
Story: Jake and Todd used different farming methods to produce their crops. Jake always tills his land, while Todd uses he no-tillage method. 
Question: Which farmer didn't provide a good environment for insects?
Output: Jake.
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: Beth and Sally are both on the high school basketball team and are about to play a match against their rival school. This match is extremely important, and students from both schools always turn out in droves to support their team. Last year, Beth and Sally's team lost so they are extra motivated this year to win. Before the game, Beth spends her time running in place and doing jumping jacks to prepare, and Sally spends her time talking to her friends who are sitting in the bleachers cheering the team on. 
Question: Are Beth's muscles more or less ready for the game than Sally's?
Output: more.
Background Paragraph: If all the other factors influencing humidity remain constant, at ground level the relative humidity rises as the temperature falls. This is because less vapor is needed to saturate the air, so vapor condenses as the temperature falls. In normal conditions, the dew point temperature will not be greater than the air temperature because relative humidity cannot exceed 100%.[4]. 
Story: Bill is wanting to go on vacation this summer, and has been looking into difference cities in which to travel too. His two cities that he has been looking at is Phoenix and St. Louis. Bill desperately hates humid temperatures, and is looking to book a city where humidity is the lowest. Bill notices that the average temperatures of Phoenix is about 90 degrees, and St. Louis is about 80 degrees. 
Question: Which city will most likely have less humidity levels based on the average summer temperatures?
Output: Phoenix.
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 10 last week. On Tuesday, there were 3500 motorcyclists. On Wednesday, there were 4500 motorcyclists. On Thursday, there were 5500 motorcyclists. On Friday, there were 6500 motorcyclists. On Saturday, there were 7500 motorcyclists. On Sunday, there were 8500 motorcyclists. On Monday, there were 9500 motorcyclists. 
Question: What day had a lower crash rate per cyclist: Wednesday or Monday?
Output: Monday.
Background Paragraph: As a cell grows, its volume increases more quickly than its surface area. If a cell was to get very large, the small surface area would not allow enough nutrients to enter the cell quickly enough for the cell’s needs. This idea is explained in Figure below . However, large cells have a way of dealing with some size challenges. Big cells, such as some white blood cells, often grow more nuclei so that they can supply enough proteins and RNA for the cell’s requirements. Large, metabolically active cells often have lots of cell protrusions, resulting in many folds throughout the membrane. These folds increase the surface area available for transport of materials into or out of the cell. Such cell types are found lining your small intestine, where they absorb nutrients from your food through protrusions called microvilli . 
Story: Mike is studying for his biology exam. He found that all body cells are not equal in size - some are large and some are small. He labeled the large cells as class A cells. Then he labeled the small cells as class B cells. He is now prepared to find the differences between them. 
Question: Which cell might have less number nuclei, class A or class B?
Output: class B.
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. It’s rate of loss has slowed with restrictions on pollutants, but it is still at risk. 
Story: Planet Earth and planet Mars both had breathable atmospheres and were inhabited by humans. People of Earth destroyed the ozone layer, people of mars were more careful and protected it. 
Question: Which planet had lower levels of UV radiation reaching its surface?
Output: Mars.
Background Paragraph: Start right above point on the temperature axis and follow the red line vertically. At very low pressure, the particles of the substance are far apart from one another and the substance is in the gas state. As the pressure is increased, the particles of the substance are forced closer and closer together. Eventually the particles are pushed so close together that attractive forces cause the substance to condense into the liquid state. Continually increasing the pressure on the liquid will eventually cause the substance to solidify. For the majority of substances, the solid state is denser than the liquid state and so putting a liquid under great pressure will cause it to turn into a solid. The line segment represents the process of sublimation, where the substance changes directly from a solid to a gas. At a sufficiently low pressure, the liquid phase does not exist. The point labeled is called the triple point . The triple point is the one condition of temperature and pressure where the solid, liquid, and vapor states of a substance can all coexist at equilibrium. 
Story: John is learning about different states of matter. So far, he recognized three states of matter, 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 learn more about their individual characteristics. 
Question: Would state B have higher or lower pressure than state C?
Output: higher.
Background Paragraph: When the temperature of reactants is higher, the rate of the reaction is faster. At higher temperatures, particles of reactants have more energy, so they move faster. They are more likely to bump into one another and to collide with greater force. For example, when you fry an egg, turning up the heat causes the egg to cook faster. The same principle explains why storing food in a cold refrigerator reduces the rate at which food spoils (see Figure below ). Both food frying and food spoiling are chemical reactions that happen faster at higher temperatures. 
Story: John just opened a coffee shop. He offers two types of coffee, coffee A and coffee B. In coffee A he mixes ingredients in hot water, but in coffee B he mixes ingredients in cold water. He also notices that his shop gets very busy in the morning, but during evening he doesn't have many customers. 
Question: In which coffee the particles would move faster, coffee A or coffee B?
Output: coffee A.
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: John has been hearing about climate change for last couple of years. He wants to understand the science behind climate change. For that, he picked up two eras in earth's history, era A and era B. Era A was hundred thousand years ago, and era B is in the present day. He now wants to compare these to eras to understand the change in climate better. 
Question: Would era B have more or less carbon dioxide in the air than era A?
Output: more.
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 Ken's plan send more or less gasses into the atmosphere than Stacy's plan?
Output: more.
Background Paragraph: fundamental quantity vs derived quantity In the language of measurement, quantities are quantifiable aspects of the world, such as time, distance, velocity, mass, temperature, energy, and weight, and units are used to describe their measure. Many of these quantities are related to each other by various physical laws, and as a result the units of some of the quantities can be expressed as products (or ratios) of powers of other units (e.g., momentum is mass times velocity and velocity is measured in distance divided by time). Those quantities whose units are expressed in terms of other units are regarded as derived quantities. Those that cannot be so expressed in terms of other units are regarded as “fundamental” quantities. 
Story: Mark has an assignment to figure out which measurements in every day life are derived quantities vs fundamental quantities. Some of the examples he has include measuring the speed of something and simply what time it is. 
Question: Given a quantity of speed, will this be considered a fundamental quantity or a derived quantity?
Output: derived.
Background Paragraph: The body's second line of defense against pathogens includes the inflammatory response. If bacteria enter the skin through a scrape, the area may become red, warm, and painful. These are signs of inflammation. Inflammation is one way the body reacts to infections or injuries. Inflammation is caused by chemicals that are released when skin or other tissues are damaged. The chemicals cause nearby blood vessels to dilate, or expand. This increases blood flow to the damaged area, which makes the area red and slightly warm. The chemicals also attract white blood cells called neutrophils to the wound and cause them to leak out of blood vessels into the damaged tissue. 
Story: Two medical students learned about the human body's defense against pathogens. Niles learned about the body's first line of defense, while Bill  learned more about the inflammatory response. 
Question: Which student learned more about skin becoming red?
Output: Bill.
Background Paragraph: Baker's yeast is the common name for the strains of yeast commonly used in baking bread and bakery products, serving as a leavening agent which causes the bread to rise (expand and become lighter and softer) by converting the fermentable sugars present in the dough into carbon dioxide and ethanol. Baker's yeast is of the species Saccharomyces cerevisiae,[1] and is the same species (but a different strain) as the kind commonly used in alcoholic fermentation, which is called brewer's yeast.[2] Baker's yeast is also a single-cell microorganism found on and around the human body. 
Story: Two groups of students made some experiments for school. Group A used brewer's yeast on flower and tried to make bread. and Group B brewed beer with brewer's yeast, then baked bread with baker's yeast. 
Question: Which group used the correct yeast for bread?
Output: Group B.
Background Paragraph: Farsightedness, or hyperopia, is the condition in which distant objects are seen clearly, but nearby objects appear blurry. It occurs when the eyeball is shorter than normal (see Figure below ). This causes images to be focused in a spot that would fall behind the retina (if light could pass through the retina). Hyperopia can be corrected with convex lenses. The lenses focus images farther forward in the eye, so they fall on the retina instead of behind it. 
Story: Kathy and Jacob are two coworkers out having a drink at a bar after a day at the office. They both wear glasses and Kathy comments that she hates that she is so farsighted and wishes there was a surgery to fix it. Jacob says that he finds it amusing she is farsighted because he himself is nearsighted. They both laugh at the opposite nature of their eye condition, and then both look at the menu on the other side of the room to decide what drinks to order next. 
Question: Who will have a harder time reading the menu?
Output: Kathy.
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: Year 2022 would be an interesting year when three comets would get scientists' attention - Comet A, Comet B, and Comet C. Comet A and C are very faint, but Comet B is very bright. Comet A would enter the inner solar system on February 10, 2022 and leave the inner solar system on February 20, 2022. Comet B would enter the inner solar system on February 18, 2022 and leave the inner solar system on February 26, 2022. Comet C would never enter the inner solar system. 
Question: Wich comet would be visible to naked eys on February 19, 2022, Comet A or Comet B?
Output: Comet B.
