Task: Question Generation
Input (English): Background Paragraph: If all the other factors influencing humidity remain constant, at ground level the relative humidity rises as the temperature falls. This is because less vapor is needed to saturate the air, so vapor condenses as the temperature falls. In normal conditions, the dew point temperature will not be greater than the air temperature because relative humidity cannot exceed 100%.[4]. 
Story: Greta loves to run. She has been trying to schedule which days of the week that would be best for her to go for her runs. She prefers days with low humidity, and isn't really concerned with the temperature. On Monday and Tuesday, the temperature will be a high of 90 degrees. On Thursday and Friday the temperature will be 75 degrees.
Output (English): Which days will Greta prefer to run on?
