Task: Question Answering
Input (English): Passage: Today I went to the dentist . I walked through the dental office doors and noticed a giant play room full of really neat toys . I sat and played until it was time for my appointment . Then the lady at the desk called my name and showed me to a big comfy chair . There were all sorts of different things in the room . Shiny things , pictures of white teeth , and machines . Then the dentist came in with a big smile and I knew we were going to get along just fine . She told me that candy can hurt teeth sometimes , but eating lots of healthy foods help them to be strong like the ones on the poster on the wall . After we were done cleaning my teeth , the lady at the desk smiled at me and gave me some toothpaste and a little box of floss . Then we went home . I love the dentist ! Question: what did the Dentist clean? Option1: Their teeth Option2: the comfy chair
