Teacher:Given a premise, an initial context, an original ending, and a counterfactual context, the task is to generate a new story ending aligned with the counterfactual context and as close to the original ending as possible. 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 and the story's general plot. The original ending is the last three sentences of the story. Also, a counterfactual context is a slight modification to the initial context. You should write a new story ending that edits the original story ending as little as possible to regain coherence with the counterfactual context. To sum up, you should write the last three sentences of a story based on the premise(first sentence) and the counterfactual context(second sentence) of the story.
Teacher: Now, understand the problem? Solve this instance: Premise: John watched the weather forecast after waking up one summer morning. 
 Initial Context: The weather forecaster said storms would be developing that day. 
 Original Ending: As John went to work he saw dark clouds developing but kept driving. John drove into a thunderstorm as he drove and had to pull over. John turned around and went home, having narrowly escaped the storm. 
 Counterfactual Context: The weather forecaster said sunny day would be developing that day.
Student:
As John went to work he saw dark clouds developing but kept driving, since he heard it would be sunny. The forecaster was wrong since John drove into a thunderstorm as he drove and had to pull over. John turned around and went home, having narrowly escaped the storm.
