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: Carly is an avid jogger, but she has recently hated jogging in high humidity weather. She doesn't mind the temperature so much, and tries to schedule her running on days of lower humidity. The next couple of days she is thinking of scheduling a run. On Thursday the high temperature will be 90 degrees, and on Friday the high will be 75 degrees.
Output (English): What day would be the worst day for Carly to run based on her preferences?
