Task: Question Answering
Input (English): Passage: My husband and I had just moved into our first home together . We had not been married very long and therefore did not have very many possessions to decorate with . We went to the store to find some things to hang on our walls to make it feel more homey . When we got home my husband found his nails and hammer . I got out our new level and we picked out exactly where we wanted to hang it . We measured carefully to ensure that it would be centered on the wall and marked the spot with a pencil so that we would remember where to drive the nail . I then hung the picture up so that the nail was in the center of the top . We used the level to be sure that it was not hanging more to one side . Question: When did their husband put a nail in the wall? Option1: Before measuring Option2: When they were hanging the picture.
Output (English): When they were hanging the picture.
