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 elevations—this 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: Ants form symbiotic associations with a range of species, including other ant species, other insects, plants, and fungi. They also are preyed on by many animals and even certain fungi. Some arthropod species spend part of their lives within ant nests, either preying on ants, their larvae, and eggs, consuming the food stores of the ants, or avoiding predators. These inquilines may bear a close resemblance to ants. The nature of this ant mimicry (myrmecomorphy) varies, with some cases involving Batesian mimicry, where the mimic reduces the risk of predation. Others show Wasmannian mimicry, a form of mimicry seen only in inquilines. 
Story: Greg was studying behavior of different organisms. He noticed that some organisms were showing inquiline behavior. He noted that behavior as case A. Then he noticed some other organisms didn't show any inquiline behavior. He noted that behavior as case B. He was astonished by the complicated interactions among organisms. 
Question: Would case B have higher or smaller risk of predation than case A?

Answer: higher.


Question: Background Paragraph: Making these healthy lifestyle choices can also help prevent some types of cancer. In addition, you can lower the risk of cancer by avoiding carcinogens , which are substances that cause cancer. For example, you can reduce your risk of lung cancer by not smoking. You can reduce your risk of skin cancer by using sunscreen. How to choose a sunscreen that offers the most protection is explained below ( Figure below ). Some people think that tanning beds are a safe way to get a tan. This is a myth. Tanning beds expose the skin to UV radiation. Any exposure to UV radiation increases the risk of skin cancer. It doesn’t matter whether the radiation comes from tanning lamps or the sun. 
Story: Danny and Bill both read about lifestyle choices and how these influence the risk of getting cancer. Danny made drastic healthier lifestyle choices, while Bill moved on and continued with his fast-food died , tanning saloons and smoking tobacco. 
Question: Which person reduced their risk of skin cancer?

Answer:
Danny.
