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: Alpine climate is the average weather (climate) for the alpine tundra. The climate becomes colder at high elevationsthis characteristic is described by the lapse rate of air: air tends to get colder as it rises, since it expands. The dry adiabatic lapse rate is 10 C per km (5.5 F per 1000 ft) of elevation or altitude. Therefore, moving up 100 metres (330 ft) on a mountain is roughly equivalent to moving 80 kilometers (45 miles or 0.75 of latitude) towards the pole. This relationship is only approximate, however, since local factors such as proximity to oceans can drastically modify the climate.
Story: There are two neighboring towns that were founded around the same time as one another. Prolot is situated high atop a tall hill which makes the walk up to the city quite daunting to travelers. However, the view when you reach the top is truly breathtaking. The town of Lire is located at the base of the hill that Prolot is on. Many tourists stop at the city of Lire to spend a night resting before they begin their journey up to Prolot the following day.
Question: Which city has a colder climate?

Answer: Prolot.

Question: Background Paragraph: Alcoholic beverages do not make the entire body warmer.[361] The reason that alcoholic drinks create the sensation of warmth is that they cause blood vessels to dilate and stimulate nerve endings near the surface of the skin with an influx of warm blood. This can actually result in making the core body temperature lower, as it allows for easier heat exchange with a cold external environment.
Story: A scientist studied the effects of alcoholic beverages on the human body during severe weather exposure. He decided to experiment on himself. He stood in -30 degrees weather for 2 hours and called it experiment A. He then repeated the experiment, the only difference being that he consumed a pint of hard liquor before and during those two hours, and that was called experiment B.
Question: When did the scientist's blood vessels dilate less, during experiment A, or during B?

Answer: experiment A.

Question: Background Paragraph: One interesting thing that has been found in plants that are consistently exposed to drought, is their ability to form a sort of "memory". In a study by Tombesi et al., they found plants who had previously been exposed to drought were able to come up with a sort of strategy to minimize water loss and decrease water use. They found that plants who were exposed to drought conditions actually changed they way the regulated their stomates and what they called "hydraulic safety margin" so as to decrease the venerability of the plant. By changing the regulation of stomata and subsequently the transpiration, plants were able to function better in situations where the availability of water decreased.
Story: Drought is major concern in the Midwest. To confront the problem scientists are trying to develop drought-resistant crops. To that end, they took a plant that was not exposed to drought. They labeled it as plant A. Then they took a similar plant, and repeatedly exposed it to drought. They labeled it as plant B. They wanted to find out what makes a plant drought-resistant.
Question: Which plant would function better with less water, plant A or plant B?

Answer:
plant B.
