Task: Question Answering
Input (English): Passage: Yesterday I woke up and decided to wear my favorite cardigan sweater to work . After taking a shower and eaten breakfast I started getting dressed . I put on a pair of jeans and then I reached for my favorite black cardigan . Of course I did not want to wear any other sweater , just this one as it was my favorite . I went to my spare room and dug my sewing kit out of the dresser . I found a thread and button that would match and I quickly threaded a needle . I began to methodically move the needle through the holes in the button to sew it back onto the sweater . Finally I was able to put my sweater on and head off to work . Question: What had fallen off? Option1: tag Option2: a button
Output (English): a button
