Task: Question Answering
Input (English): Background Paragraph: Human beings invented agriculture about 10,000 years ago. This provided a bigger, more dependable food supply. It also allowed people to settle down in villages and cities for the first time. Birth rates went up because there was more food and settled life had other advantages. Death rates also rose because of crowded living conditions and diseases that spread from domestic animals. Because the higher birth rates were matched by higher death rates, the human population continued to grow very slowly. 
Story: Harry and Kim studied ancient humans. Kim studied a 15000 year-old settlement, before humans invented agriculture, while Harry studied a 5000 year-old village. 
Question: Which student studied about a village that had a less dependable food supply?
Output (English): Kim.
