TASK DEFINITION: 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.
PROBLEM: Background Paragraph: The water level is seasonal, being lowered by about 10 feet (3.0 m) over the winter. The reservoir fills in the spring from snow melt and underground springs. The lake is usually at full level by late spring, but in the occasional years of low snow melt and low rainfall, it may remain up to several feet below its typical level. Water is let out of the lake in the fall so that ice will not damage docks and other structures around the lake. This also leads to excellent water quality, as a significant portion of the water is replaced every year. 
Story: Alpine lake had low water levels this spring although the lake is usually at full level by late spring. Last year was a very wet year with lots of precipitation. Rangers were planning on letting water out of the lake in the fall so that ice will not damage docks and other structures around the lake. The water levels were high enough in the fall so they proceeded in lowering the water level by 10 feet.. 
Question: When are the lake water levels lower, during winter or during late spring?

SOLUTION: during winter.

PROBLEM: 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: Roger had a busy day storing XML. At 4 PM, he stored 22211 Gigabytes to the database. At 5 PM, he stored 33322 Gigabytes to the database. At 6 PM, he stored 44433 Gigabytes to the database. At 7 PM, he got dinner. At 8 PM, he stored 55544 Gigabytes to the database. At 9 PM, he stored 66655 Gigabytes to the database. At 10 PM, he went to sleep to finish storing XML tomorrow. 
Question: What time did access times go up: 4 PM or 10 PM?

SOLUTION: 4 PM.

PROBLEM: Background Paragraph: Huge amounts of chemicals, such as fertilizers and pesticides, are applied to farm fields (see Figure below ). Some of the chemicals are picked up by rainwater. Runoff then carries the chemicals to nearby rivers or lakes. Dissolved fertilizer causes too much growth of water plants and algae. This can lead to dead zones where nothing can live in lakes and at the mouths of rivers. Some of the chemicals can infiltrate into groundwater. The contaminated water comes up in water wells. If people drink the polluted water, they may get sick. 
Story: Jimbo and Jedd are both farmers who have lakes and water wells downstream from their farms. Jimbo's products have been in high demand recently, so he has started to use very high amounts of fertilizers on his farms. Jedd has recently decreased the amount of fertilizer he uses because his products aren't wanted as much by the people in his town. 
Question: Who will be more likely to cause people to get sick?

SOLUTION:
Jimbo.
