You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
In this task, you're given the middle and ending of a three-part story. Your job is to complete the short story by writing a probable beginning of the story. Generated sentences must be short, have fewer than 10 words, and be simple as if narrating to a child. Avoid using any irrelevant extra information when creating the beginning, and use names (e.g. Jack, Barbara,...) instead of pronouns (e.g. he / she) wherever possible.

Middle: Helen planned to drive to Canada but it started snowing heavily. Ending: Helen stayed home instead and planned to go another day.
Solution: Helen lived in America.
Why? Mention of the destination country name and driving implies that Helen is from a nearby foreign country.

New input: Middle: Dave studied very hard. Ending: The next day he found out he had passed and was very happy.
Solution:
Dave was very nervous about his upcoming science test.
