Task: Question Answering
Input (English): Passage: I wanted to rearrange my living room to give it a new look . I realized that I would need help moving the furniture because it was very heavy . I called my friend who is very strong and he came over to help me . We put grips underneath the legs of the couch so that it would not scratch the floor , and so that it would be easier to move . We each took one side of the couch and gently pushed it across the room . I was very careful because I did n't want to hurt my back while pushing a heavy object . Then I decided I wanted to move my coffee table to the place where the couch used to sit . The coffee table was not very heavy , so I pushed it where the couch had been all by myself . I thanked my friend for helping and he went home . Question: When did they move the couch? Option1: after putting grips on Option2: after moving the coffee table.
Output (English): after putting grips on
