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.

Input: Consider Input: Background Paragraph: Two important devices depend on electromagnetic induction: electric generators and electric transformers. Both devices play critical roles in producing and regulating the electric current we depend on in our daily lives. Electric generators use electromagnetic induction to change kinetic energy to electrical energy. They produce electricity in power plants. Electric transformers use electromagnetic induction to change the voltage of electric current. Some transformers increase voltage and other decrease voltage.
Story: Bob works for the local electric power company. Part of is job involves checking the generators and transformers. His work schedule allows him to work on the generator tagged as gen A only on Mondays, and the transformer tagged as tran B only on Tuesdays.
Question: Which one would produce electric current, gen A or tran B?

Output: gen A.

Input: Consider Input: Background Paragraph: Earthquakes may take place every day near a volcano. But before an eruption, the number and size of earthquakes increases. This is the result of magma pushing upward into the magma chamber. This motion causes stresses on neighboring rock to build up. Eventually the ground shakes. A continuous string of earthquakes may indicate that a volcano is about to erupt. Scientists use seismographs to record the length and strength of each earthquake.
Story: Pam and Jane were two researchers. Pam studied sedimentary rocks while Jane studied volcanoes and related phenomena, such as earthquakes.
Question: Which researcher didn't observe what happens before a volcanic eruption?

Output: Pam.

Input: Consider Input: 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: Tom had a busy day storing XML. At 2 PM, he stored 10 Gigabytes to the database. At 3 PM, he stored 20 Gigabytes to the database. At 4 PM, he stored 30 Gigabytes to the database. At 5 PM, he got dinner. At 6 PM, he stored 40 Gigabytes to the database. At 7 PM, he stored 50 Gigabytes to the database. At 8 PM, he went to sleep to finish storing XML in the morning.
Question: What time did CPU load go up: 7 PM or 5 PM?
Output: 7 PM.
