Task: Question Answering
Input (English): Passage: Today I decided to put new flooring in my bedroom . I had already taken out my old flooring and was just left with a plain , ugly wood floor , called a sub-floor . I cleaned and swept my sub floor and laid down a thin layer of padding that goes underneath your flooring . I opened up the package and took out my long floorboards . These floorboards fit together with each other , just like a puzzle . I started on one side of my room and laid the floorboards together , fitting each new piece to the previous piece I had just put down . Sometimes I had to use my hand or a rubber mallet to bang the floorboards together , because it was such a tight fit . Question: When did they buy the wooden floorboards? Option1: after removing the old flooring Option2: at the end
Output (English): after removing the old flooring
