Task: Question Generation
Input (English): Background Paragraph: Other pathogens spread when they get on objects or surfaces. A fungus may spread in this way. For example, you can pick up the fungus that causes athlete’s foot by wearing shoes that an infected person has worn. You can also pick up this fungus from the floor of a public shower or other damp areas. After acne, athlete’s foot is the most common skin disease in the United States. Therefore, the chance of coming in contact with the fungus in one of these ways is fairly high. 
Story: Two brothers worked out a few times per week at the same gym. Tim got athlete's food from the gym, but Dan didn't.
Output (English): Which brother didn't pick up the second most common skin disease in the US?
