Task: Question Answering
Input (English): Background Paragraph: A few insects, such as mayflies and some moths, never eat. That’s because their lives are over in just a few hours or days. Once these insects become adults, they lay eggs, and then die. On the other hand, some insects are very healthy eaters. A silkworm eats enough leaves to increase its weight more than 4,000 times in just 56 days, as the silkworm increases in size about 10,000 times since birth. A locust eats its own weight in plants every day. Just imagine eating your own weight in food every day. You probably couldn't. You would most likely get very sick even if you tried. 
Story: Two entomologists liked studying all types of insects and arthropods. Bill was focused on insects that never eat. His buddy Paul was more focused on the feeding habits of other insects that eat a lot of food. 
Question: Which friend didn't learn that a locust eats its own weight in plants every day?
Output (English): Bill.
