Task: Question Answering
Input (English): Passage: I like to keep my pets in the house a lot of the time . It 's good to keep them out of the sun and let them spend time around the family . One of the biggest problems , though , is that they often shed hair . Just this past weekend , one of my dogs shed a lot of hair on the carpet that needed to be vacuumed . The first thing I did was use a special pet hair brush across the carpet to catch as much loose hair as possible . I put the loose hair into a garbage bag , and threw it away . Then , I plugged in my vacuum and went over the entire carpet . After the first round , I went over the carpet again with the brush just in case there was any hair left behind . Finally , I vacuumed the carpet a second time to clean up as much pet hair , dirt , and trash as possible . Question: What was making dirty the carpet? Option1: Pet hair Option2: trash
Output (English): Pet hair
