Task: Question Answering
Input (English): Passage: One of the buttons came off on my shirt , so I have to sew it back on . Sewing a button can be tricky , since you need a very steady hand . I get some thread and a sewing needle and get to work . I tie a knot on the end of my thread , and put the needle through the underside of my shirt to where the button is . I guide the needle from under the shirt through one of the holes in the button , and then back through another hole . I do this many times , alternating between the four holes to make sure the button 's on tight . There are a lot of ways you can sew a button , but I like to do it so the stitch looks like an X . Once I 've done it enough times , I can tie off my thread and my button 's as good as new ! Question: When do they sew? Option1: after button fell off Option2: Before finding the button
Output (English): after button fell off
