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: Alberta's electrical demand varies throughout the day and across the seasons. When individuals are fixing supper and using home appliances, demand for power goes up, as it does during heat waves and cold snaps. It tapers off during spring and fall. Like other mechanical devices, generators fail from time to time. If they are wind-powered, their output varies with the wind.
Story: Tony is in charge of a power station in Alberta. He has been tasked with turning on and off generators depending on the demand for power. He has been ordered to try and be efficient as possible, turning off generators in low demand times, and turning them on in high demand times to satisfy needs. On Monday and Tuesday, Alberta saw record high temperatures, and on Thursday and Friday, things cooled off for a more moderate and comfortable temperature.
Question: Which days did Tony most likely turn on more generators?

Answer: Monday and Tuesday.

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: 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?

Answer: 4 PM.

Question: Background Paragraph: Friction between the atmosphere and the Earth's surface causes a 20% reduction in the wind at the surface of the Earth.[10] Surface roughness also leads to significant variation of wind speeds. Over land, winds maximize at hill or mountain crests, while sheltering leads to lower wind speeds in valleys and lee slopes.[11] Compared to over water, maximum sustained winds over land average 8% lower.[12] More specifically, over a city or rough terrain, the wind gradient effect could cause a reduction of 40% to 50% of the geostrophic wind speed aloft; while over open water or ice, the reduction is between 10% and 30%.[8][13][14].
Story: Bill is going on vacation this week, and is visiting two local sites. One, is Deep Valley, and the other is Mount Tall. He will be going to Deep Valley on Monday and Tuesday, and then visit Mount Tall on Thursday and Friday. He has decided that on his trip he wants to fly his kite at some point, but also wants to have a picnic on the other days. He would prefer an area of high wind for flying his kite, and an area of low winds to have his picnic so his food doesn't blow asunder.
Question: Will there be more or less wind where Bill goes on Tuesday than Friday?

Answer:
less.
