Teacher:Given a premise, an initial context, an original ending, and a new ending, the task is to generate the counterfactual context that is aligned with the new ending. Each instance consists of a five-sentence story. The premise is the first sentence of a story, and the second sentence, which is the initial context, provides more information about the story's context. The original ending is the last three sentences of the story. Also, you are given a new ending that can provide the new story with the same premise. You should write a counterfactual context to explain the small differences between the original and new endings. More specifically, a story context contains the general plot of the story. And a counterfactual context is a slight modification to the initial context. To sum up, you should write the second sentence of a story based on the premise(first sentence) and the new ending(last three sentences) of the story.
Teacher: Now, understand the problem? Solve this instance: Premise: The weather report said that it would be a sunny day.
Initial Context: I decided not to bring an umbrella with me.
Original Ending: When I was outdoors, it started to rain. I went into a nearby store. I bought an umbrella at the store.
New ending: Of course the weather report was wrong because when I was outdoors it started to rain. I continued on my way to a nearby store. I stayed dry with my umbrella and trench coat.
Student:
I decided to bring my umbrella and trench coat anyway.
