Task: Question Answering
Input (English): Passage: I bought a really beautiful painting for my new flat . I needed to put the painting up on the wall to display it . I found the perfect spot on the wall that I wanted to put it on . I went to my tool bag and got a hammer , a nail , a piece of chalk , and a leveler . I carefully put the nail on the spot , then took my hammer and hit it a few times . When I checked to make sure it was going in straight , I kept hammering it in . I hammered it in until it was half way in the wall and half way not . I put the hammer down . I then took the level and made sure it was even . When I was sure I had it hung even , I put my tools away . Question: They marked the spot that they wanted to put the nail with what? Option1: A pen. Option2: a piece of chalk
Output (English): a piece of chalk
