Task: Question Answering
Input (English): Passage: Last Saturday , a friend who was visiting my house commented that it looked like I had n't tended to my lawn in a while . I realized she was right -- the weeds were growing pretty tall , and I had n't cut the grass in weeks . I decided it was time to mow the lawn the next day . I rolled the lawnmower over to the lawn , and then turned the lawnmower on . It started roaring , signaling that it was on and ready to cut grass . I mowed the grass in neat rows , starting on one side of my lawn and mowing all the way to the other side . After I inspected my work , I decided I was happy with it . The grass looked much neater . I turned off the lawnmower and returned it to the garage . Question: What did they go back and forth with? Option1: lawnmower Option2: friend
Output (English): lawnmower
