Task: Question Answering
Input (English): Background Paragraph: Located mostly in the Arctic north polar region in the middle of the Northern Hemisphere, the Arctic Ocean is almost completely surrounded by Eurasia and North America. It is partly covered by sea ice throughout the year and almost completely in winter. The Arctic Ocean's surface temperature and salinity vary seasonally as the ice cover melts and freezes; its salinity is the lowest on average of the five major oceans, due to low evaporation, heavy fresh water inflow from rivers and streams, and limited connection and outflow to surrounding oceanic waters with higher salinities. The summer shrinking of the ice has been quoted at 50%. The US National Snow and Ice Data Center (NSIDC) uses satellite data to provide a daily record of Arctic sea ice cover and the rate of melting compared to an average period and specific past years. 
Story: The inuit tribe lived and hunted on the shores of the Arctic ocean., very close to the North pole. The weather there was very cold throughout the year. Their distant cousins the umpala tribe, lived thousands of miles away, on the shores of the Indian ocean, where the weather was humid and warm, in a tropical climate. 
Question: Which tribe experienced colder winters?
Output (English): inuit.
