Task: Question Generation
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: Two neighboring ponds were stocked with adult fish last year. Hill pond had a very nice winter and the fish started reproducing normally, while Mound pond had no fish reproducing this spring.
Output (English): Which pond's stock had a slim chance of increasing?
