Task: Question Generation
Input (English): Background Paragraph: The temperature of a body of water directly affects the amount of dissolved oxygen it can hold. Following Henry's law, as water becomes warmer, oxygen becomes less soluble in it. This property leads to daily anoxic cycles on small geographic scales and seasonal cycles of anoxia on the larger scale. Thus, bodies of water are more vulnerable to anoxic conditions during warmest period of the day and during the summer months. This problem can be further exacerbated in the vicinity of industrial discharge where warm water used to cool machinery is less able to hold oxygen than the basin to which it is released. 
Story: Dan visited Twin lakes every year. The interesting fact about them wast that, while Twin I had a very cold water all year, Twin II lake had very warm waters year round.
Output (English): Which body of water had fewer daily anoxic cycles?
