instruction:
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.
question:
Background Paragraph: Storing large volumes of data When storing XML to either file or database, the volume of data a system produces can often exceed reasonable limits, with a number of detriments: the access times go up as more data is read, CPU load goes up as XML data takes more power to process, and storage costs go up. By storing XML data in Fast Infoset format, data volume may be reduced by as much as 80 percent.
Story: Odis had a busy day storing XML. At 8 AM, he stored 202 Gigabytes to the database. At 9 AM, he stored 302 Gigabytes to the database. At 10 AM, he stored 402 Gigabytes to the database. At 11 AM, he got breakfast. At 12 PM, he stored 502 Gigabytes to the database. At 1 PM, he stored 602 Gigabytes to the database. At 2 PM, she went to sleep to finish storing XML later on that night.
Question: What time did access times go up: 10 AM or 11 AM?
answer:
10 AM.

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?
answer:
Adam.

Background Paragraph: Apex predators affect prey species' population dynamics and populations of other predators, both in aquatic and in terrestrial ecosystems. Non-native predatory fish, for instance, have sometimes devastated formerly dominant predators. A lake manipulation study found that when the non-native smallmouth bass was removed, lake trout, the suppressed native apex predator, diversified its prey selection and increased its trophic level. As a terrestrial example, the badger, an apex predator, predates on and also competes with the hedgehog, a mesopredator, for food such as insects, small mammals, reptiles, amphibians and ground-nesting bird's eggs. Removal of badgers (in a trial investigating bovine tuberculosis) caused hedgehog densities to more than double. Predators that exert a top-down control on organisms in their community are often considered keystone species. Humans are not considered apex predators because their diets are typically diverse, although human trophic levels increase with consumption of meat.
Story: Rob is a biologist who is interested in native species conservation. To that end, he conducted two studies, case A and case B. In case A, a non native apex predator C was introduced in formerly apex predator D's habitat. In case B, same non native apex predator C was removed from formerly apex predator D's habitat. He now needs to analyze the results of these studies.
Question: Would predator D's prey selection be less or more diversified in case B than in case A?
answer:
more.
