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: Hemophilia is the name of a group of hereditary diseases that affect the body's ability to control blood clotting. Hemophilia is caused by a lack of clotting factors in the blood. Clotting factors are normally released by platelets. Since people with hemophilia cannot produce clots, any cut can put a person at risk of bleeding to death. The risk of internal bleeding is also increased in hemophilia, especially into muscles and joints. This disease affected the royal families of Europe. 
Story: Mary had two twin daughters, Mimi and Coco. Coco was healthy, but Mimi had hemophilia. Mimi took frequent trips to the doctor's office. 
Question: Which girl had more clotting factors in the blood?

Output: Coco.


Input: Consider Input: Background Paragraph: Often, foreign exchange controls can result in the creation of black markets to exchange the weaker currency for stronger currencies. This leads to a situation where the exchange rate for the foreign currency is much higher than the rate set by the government, and therefore creates a shadow currency exchange market. As such, it is unclear whether governments have the ability to enact effective exchange controls.[1]. 
Story: In the beginning of this century there was scandal in the financial market regarding black market trading. A trader named Trader A was working for Bank A. He noticed country M has pegged its currency to a fixed price while country N did not do that. He opted to trade country M currency. Across the aisle his colleague trader B was working for bank B. He traded country N's currency. 
Question: Would trader A be engaged or not be engaged in black market trading?

Output: be engaged.


Input: Consider Input: Background Paragraph: Thermoclines, or sudden changes in temperature. Where the air temperature is higher than the water temperature, shallow water may be warmed by the air and the sunlight but deeper water remains cold resulting in a lowering of temperature as the diver descends. This temperature change may be concentrated over a small vertical interval, when it is called a thermocline.[3][4]
Where cold, fresh water enters a warmer sea the fresh water may float over the denser saline water, so the temperature rises as the diver descends.[3]
In lakes exposed to geothermal activity, the temperature of the deeper water may be warmer than the surface water. This will usually lead to convection currents.[3]. 
Story: Ryan explored two lakes; Big lake, and Arrow lake to the south. Arrow lake had a river flowing into it, while Big lake presented evidence of underwater geothermal activity. Many divers drowned in Arrow lake because of temperature shock. 
Question: Which lake had more occurrences of divers drowning?


Output: Arrow lake.
