Task: Question Answering
Input (English): Background Paragraph: Fish reproduce sexually. They lay eggs that can be fertilized either inside or outside of the body. In most fish, the eggs develop outside of the mother's body. In the majority of these species, fertilization also takes place outside the mother's body. The male and female fish release their gametes into the surrounding water, where fertilization occurs. Female fish release very high numbers of eggs to increase the chances of fertilization. 
Story: Tim and Dan both studied reproduction in college. Dan studied plant reproduction while Tim studied fish reproduction. 
Question: Which person studied less about the ways fish eggs get fertilized?
Output (English): Dan.
