Task: Question Generation
Input (English): Background Paragraph: Fish mortality is a parameter used in fisheries population dynamics to account for the loss of fish in a fish stock through death. The mortality can be divided into two types:

Natural mortality: the removal of fish from the stock due to causes not associated with fishing. Such causes can include disease, competition, cannibalism, old age, predation, pollution or any other natural factor that causes the death of fish. In fisheries models natural mortality is denoted by (M).[1]
Fishing mortality: the removal of fish from the stock due to fishing activities using any fishing gear.[1] It is denoted by (F) in fisheries models. 
Story: Tony is about to go on two fishing trips in the up coming week. On Friday, he is going to Bear Lake, which is located near a factory that has been known to dump waste into the lake. On Saturday, he is going to Fox Lake, which is in a secluded valley.
Output (English): Will fishing on Friday more or less likely be more fruitful than fishing on Saturday?
