input question: You are given a new situation: Two competing countries used different energy sources to produce their electricity. Turkey used mostly fossil fuels, while Greece used nuclear power. and a hint : In the U.S., the majority of electricity is produced by burning coal or other fossil fuels. This causes air pollution that harms the health of living things. The air pollution also causes acid rain and contributes to global warming. In addition, fossil fuels are nonrenewable resources, so if we keep using them, they will eventually run out. The main advantage of nuclear energy is that it doesn't release air pollution or cause the other environmental problems associated with the burning of fossil fuels. On the other other hand, radioactive elements are nonrenewable like fossil fuels and could eventually be used up. Please answer this question : Which country used fewer radioactive elements????
output answer: Turkey

input question: You are given a new situation: 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. and a hint : 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. Please answer this question : Would particles of reactants in test B have lower or higher energy than particles in test A????
output answer: lower

input question: You are given a new situation: Dan and Joe studied animals for biology class. Joe had to study predator animals, while Dan studied herbivores and grazers. and a hint : Predators play an important role in an ecosystem. For example, if they did not exist, then a single species could become dominant over others. Grazers on a grassland keep grass from growing out of control. Predators can be keystone species . These are species that can have a large effect on the balance of organisms in an ecosystem. For example, if all of the wolves are removed from a population, then the population of deer or rabbits may increase. If there are too many deer, then they may decrease the amount of plants or grasses in the ecosystem. Decreased levels of producers may then have a detrimental effect on the whole ecosystem. In this example, the wolves would be a keystone species. Please answer this question : Which student learned more about potential keystone species????
output answer: Dan

input question: You are given a new situation: John wanted to revisit Aristotle's theory of tetrapods. To that end, he chose two tetrapods, tetA and tetB. An adult tetA was heavier than an adult tetB. Moreover, a tetA had longer gestation period than tetB. He needed to figure out how their characteristics fit Aristotle's theory. and a hint : From the data he collected and documented, Aristotle inferred quite a number of rules relating the life-history features of the live-bearing tetrapods (terrestrial placental mammals) that he studied. Among these correct predictions are the following. Brood size decreases with (adult) body mass, so that an elephant has fewer young (usually just one) per brood than a mouse. Lifespan increases with gestation period, and also with body mass, so that elephants live longer than mice, have a longer period of gestation, and are heavier. As a final example, fecundity decreases with lifespan, so long-lived kinds like elephants have fewer young in total than short-lived kinds like mice. Please answer this question : Would tetB live longer or shorter than tetA????
output answer:
shorter
