Q: Background: 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. As a result, they are more likely to bump into one another and to collide with greater force. For example, food spoils because of chemical reactions, and these reactions occur faster at higher temperatures (see the bread on the left in the Figure below ). This is why we store foods in the refrigerator or freezer (like the bread on the right in the Figure below ). The lower temperature slows the rate of spoilage. Paragraph: John was pondering about what makes a chemical reaction faster or slower. To find the answer he did two tests, test A and test B. In test A he warmed up the reactants, but in test B he cooled down the reactants. To see a practical example of these tests he conducted two more tests, test C and test D. In test C he kept a food item in the refrigerator, but in test D he kept the same food item on the table top. Given the paragraph above, please answer correctly the following question: In which test particles would move faster, test A or test B?
A: test A

Q: Background: Earthquakes may take place every day near a volcano. But before an eruption, the number and size of earthquakes increases. This is the result of magma pushing upward into the magma chamber. This motion causes stresses on neighboring rock to build up. Eventually the ground shakes. A continuous string of earthquakes may indicate that a volcano is about to erupt. Scientists use seismographs to record the length and strength of each earthquake. Paragraph: Two sister villages, both situated near volcanoes, experience daily earthquakes. Green village started recording an increased size and number of earthquakes one day. Blue village didn't experience a change in the number of earthquakes. Given the paragraph above, please answer correctly the following question: Which village started experiencing less ground shaking?
A: Blue

Q: Background: 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. Paragraph: Harry and Kim studied ancient humans. Kim studied a 15000 year-old settlement, before humans invented agriculture, while Harry studied a 5000 year-old village. Given the paragraph above, please answer correctly the following question: Which student studied about a village that had a lower death rate?
A: Kim

Q: Background: One interesting thing that has been found in plants that are consistently exposed to drought, is their ability to form a sort of "memory". In a study by Tombesi et al., they found plants who had previously been exposed to drought were able to come up with a sort of strategy to minimize water loss and decrease water use. They found that plants who were exposed to drought conditions actually changed they way the regulated their stomates and what they called "hydraulic safety margin" so as to decrease the venerability of the plant. By changing the regulation of stomata and subsequently the transpiration, plants were able to function better in situations where the availability of water decreased. Paragraph: In a greenhouse, two new plants have just been planted. Flower D has come from a region of little rainfall. Flower E was taken from an area that sees rain nearly every day of the year. Given the paragraph above, please answer correctly the following question: Which flower would be worse at handling not being watered for a long period of time?
A:
Flower E
