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.

Example Input: 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: Bob has been wanting to go on vacation to the nearest lake in his area. He prefers to go to the lake when it is at it's highest level. He doesn't want to go during the summer, and has decided he must choose between the fall, and the spring for the best temperatures. 
Question: Will the fall or the spring more than likely have a lower water level?
Example Output: fall.

Example Input: Background Paragraph: Because of human activities, there is more carbon dioxide in the atmosphere today than in the past hundreds of thousands of years. Burning fossil fuels and has released great quantities of carbon dioxide into the atmosphere. Cutting forests and clearing land has also increased carbon dioxide into the atmosphere because these activities reduce the number of autotrophic organisms that use up carbon dioxide in photosynthesis. In addition, clearing often involves burning, which releases carbon dioxide that was previously stored in autotrophs. 
Story: Two cities had different energy source. Big city burned fossil fuels cut forests and cleared land, while Blue city used alternative sources of energy. 
Question: Which city cleared fewer lands?
Example Output: Blue.

Example Input: Background Paragraph: The Tasmanian devil is a nocturnal and crepuscular hunter, spending the days in dense bush or in a hole.[64] It has been speculated that nocturnalism may have been adopted to avoid predation by eagles and humans.[65] Young devils are predominantly crepuscular.[66] There is no evidence of torpor.[67]

Young devils can climb trees, but this becomes more difficult as they grow larger.[68][69] Devils can scale trees of trunk diameter larger than 40 cm (16 in), which tend to have no small side branches to hang onto, up to a height of around 2.5–3 m (8.2–9.8 ft). Devils that are yet to reach maturity can climb shrubs to a height of 4 metres (13.1 ft), and can climb a tree to 7 m (23 ft) if it is not vertical.[70] Adult devils may eat young devils if they are very hungry, so this climbing behaviour may be an adaptation to allow young devils to escape.[71] Devils can also swim and have been observed crossing rivers that are 50 metres (160 ft) in width, including icy cold waterways, apparently enthusiastically. 
Story: The scientists examined both the Eastern and the Western slopes of the mountain. They reached the conclusion that the Western slope was inhabited by many more adult Tasmanian devils than the Eastern slope. 
Question: Which slope had more instances of devils eating young devils?
Example Output:
Western.
