input question: Given the background: The theory of evolution by natural selection was proposed at about the same time by both Charles Darwin and Alfred Russel Wallace, shown in Figure below , and was set out in detail in Darwin's 1859 book On the Origin of Species . Natural selection is a process that causes heritable traits that are helpful for survival and reproduction to become more common, and harmful traits, or traits that are not helpful or advantageous for survival to become more rare in a population of organisms. This occurs because organisms with advantageous traits are more "fit" to survive in a particular environment and have "adapted" to the conditions of that environment. These individuals will have greater reproductive success than organisms less fit for survival in the environment. This will lead to an increase in the number of organisms with the advantageous trait(s) over time. Over many generations, adaptations occur through a combination of successive, small, random changes in traits, and natural selection of those variants best-suited for their environment. Natural selection is one of the cornerstones of modern biology. and the situation: David wants to revisit the theory of evolution proposed by Darwin and Wallace. He is particularly interested in two species of deer, species A and species B. Species A has some helpful traits, but species B has some harmful traits. He is planning to write a paper on why some species are greater in number while others are smaller in number. Answer the following question: Which species would have greater reproductive success, species A or species B????
output answer: species A

input question: Given the background: 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. and the situation: the students used yeasts in two different experiments: they baked bread using baker's yeast, and made beer, using brewer's yeast. They learned a lot about sugars and chemistry. Answer the following question: Which yeast is worse for bakery products????
output answer: brewer's yeast

input question: Given the background: Rainfall in an area is important because it influences the rate of weathering. More rain means that more rainwater passes through the soil. The rainwater reacts chemically with the particles. The top layers of soil are in contact with the freshest water, so reactions are greatest there. High rainfall increases the amount of rock that experiences chemical reactions. High rainfall may also carry material away. This means that new surfaces are exposed. This increases the rate of weathering. and the situation: Two parcels of land , parcel Q and parcel H are situated in the same county about 20 miles away. Parcel Q received a greater amount of rainfall than parcel H, therefore the soil was more affected by the rain. Answer the following question: Which parcel had more water interact chemically with the soil particles????
output answer: parcel Q

input question: Given the background: Some materials have negative heats of solution; the dissolution of one of these solutes in water is an exothermic process. Heat is released, causing a net increase in the temperature of the solution. Conversely, other substances have positive heats of solution. For example, the dissolution of potassium nitrate in water is an endothermic process. The resulting absorption of energy causes the solution to become colder. Calculations involving heats of solutions follow the same basic approach that we have used with other enthalpy problems. and the situation: John is conducting an experiment in his chemistry lab. His goal is to find a chemical solution that can regulate temperature. To that end, he considered two processes, process A and process B. Process A is an exothermic process, but process B is an endothermic process. Answer the following question: Which process would involve positive heats of solution, process A or process B????
output answer:
process B
