Task: Question Answering
Input (English): Passage: Yesterday , I went to the dentist . I brushed my teeth first , so she would n't think they were crusty . Then I walked to her office , which is only a few blocks from my house . I got there fifteen minutes before my appointment , and told the woman behind the counter I had an appointment with Dr. Le . I looked at an old magazine while I waited . Soon another woman came and told me they were going to take an X-ray . She led me back to a small room . Then she put a small film holder in my mouth and told me to hold still . She left the room for a minute , and I think I heard a click , but I did n't feel anything . Then she came back and led me to the dentist 's chair . The dentist smiled , and asked me how I was feeling . They were fine ! She told me to keep brushing and flossing , and to come back to see her in six months . I was glad to say good-bye . Question: When did they open wide? Option1: after dental exam Option2: when the dentist came in
Output (English): when the dentist came in
