You are given a background paragraph that describes one or more causal or qualitative relationships such as a relationship in economics or a scientific law and a story that makes use of the concepts or the relationship described in the provided paragraph. You are also given a question about the story that requires an understanding of the relationship described in the background paragraph and the story. You need to come up with an answer to the given question; the answer will be a span from either the question or the story. In order to correctly answer the given question, you need to understand the relationship mentioned in the background paragraph and should be able to use it to understand that in the story. Your answer can not consist of any word that is not mentioned in any of these: the background paragraph, the story, or the question. You can directly copy and paste a span from the story or the question while answering the given question.

[Q]: Background Paragraph: Second, sharing opinions with peers is helpful in building and increasing one's confidence. Clearly expressing what one is trying to say requires confidence and sufficient knowledge; people need to self dress what to say with their own knowledge or experiences. Thus, giving useful feedback definitely strengthens one's confidence. Moreover, peer feedback helps student to take more responsibilities in learning process. Besides doing assignments, students have to read others' work carefully as well so that one is not only responsible for his/her own work but also the others'. 
Story: Stephanie is very active and social with the other students at school. She talks to her friends about the projects she is working on and they talk about what she can improve on and what areas she is excelling in. Adam is very quite and usually works on his projects alone and doesn't socialize with others at school. 
Question: Who is more likely to excel less in their studies based on their social behavior, Stephanie or Adam?
[A]: Adam.


[Q]: Background Paragraph: You generally can’t see, smell, taste, hear, or feel radiation. Fortunately, there are devices such as Geiger counters that can detect radiation. A Geiger counter, like the one pictured in the Figure below , contains atoms of a gas that is ionized if it encounters radiation. When this happens, the gas atoms change to ions that can carry an electric current. The current causes the Geiger counter to click. The faster the clicks occur, the higher the level of radiation. You can see a video about the Geiger counter and how it was invented at the URL below. 
Story: Keith landed a job with the EPA. As part of his training he needed to learn how the Geiger counter works. To learn more about the counter he tested it in three different locations, location A, location B, and location C. Location A had very high radiation; location B had low radiation; and location C didn't have any radiation. Keith learned how the counter works in locations with varying degrees of radiation. 
Question: Which location would have slower clicks, location A or location B?
[A]: location B.


[Q]: 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: Which time would more likely see reduced marine primary productivity, time A or time B?
[A]:
time B.
