Task: Question Answering
Input (English): Background Paragraph: The jejunum is the second part of the small intestine, where most nutrients are absorbed into the blood. As shown in Figure below , the mucous membrane lining the jejunum is covered with millions of microscopic, fingerlike projections called villi (singular, villus). Villi contain many capillaries, and nutrients pass from the villi into the bloodstream through the capillaries. Because there are so many villi, they greatly increase the surface area for absorption. In fact, they make the inner surface of the small intestine as large as a tennis court!. 
Story: Paul and Dirk were studying the human digestive system. paul studied more about the stomach, while Dirk studied more about the jejunum. 
Question: Which student read more about villi?
Output (English): Dirk.
