Task: Question Answering
Input (English): Passage: We are renovating our whole home since we purchased it a month ago . I told my husband that I wanted to buy a upper , so we could put our own mark on the house . The task has been difficult but we have had fun accomplishing each task .  I hired a contractor to do all the flooring in our home . We had everything taken out of the rooms and all the old carpet was stripped . I picked a beautiful maple wood flooring to go in the whole house .  The contractors have been hard at work for a couple of days , installing each plank of wood at a time .  After the floor is laid out in one room , they cover it with brown paper and start another room .  After a few days , they finished the floors and it came out just as I imagined . Question: When could the loud banging be heard throughout the whole house? Option1: When they were buying the maple wood. Option2: When the contractors were installing the floor.
Output (English): When the contractors were installing the floor.
