Task: Question Answering
Input (English): Background Paragraph: Another example of negative feedback has to do with blood glucose levels. When glucose (sugar) levels in the blood are too high, the pancreas secretes insulin to stimulate the absorption of glucose and the conversion of glucose into glycogen, which is stored in the liver. As blood glucose levels decrease, less insulin is produced. When glucose levels are too low, another hormone called glucagon is produced, which causes the liver to convert glycogen back to glucose. 
Story: Tim and Fred were two students. Tim studied about negative feedback and the pancreas, while Fred studied about the stomach and the jejunum. 
Question: Which student read less about blood glucose levels?
Output (English): Fred.
