Task: Question Answering
Input (English): Passage: I often babysit for a family with three young children . It is very difficult to get all of the kids ready for bed . When I finally get them all in pajamas with teeth brushed and faces washed , I tell them to get comfortable in their beds . Then , I tell them a story to settle them down and give them good dreams . I think of characters that are like them but just a little different . For example , one character might be an 8 year girl with a brother and a sister but she 's also a royal princess . When I 'm telling the story , the characters always face a problem . Once I told the kids about the problem , I told them how the characters confronted the problem and solved it together .

The kids went to sleep . Question: What do they always start with "Once upon a time"? Option1: the bedtime story Option2: a sentence
