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: Grace is trying to set up a running schedule for herself. She prefers running on days when the humidity is at it's lowest so she doesn't feel so muggy. On Wednesday the high temperature is going to be 90 degrees, and on Thursday the high temperature is going to be 75 degrees.
Output (English): Which day should Grace avoid doing her run?
