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: Pat had been training for her first 5K all summer. 
 Initial Context: She ran the Fall Festival race. 
 Original Ending: She had set a goal to finish in 30 minutes flat. She pushed herself as hard as she could. She finished the race in just a little over 29 minutes! 
 Counterfactual Context: She trained too hard and broke her leg.
Student:
She had set a goal to finish in 30 minutes flat. She pushed herself as hard as she could the next year though. She finished the race in just a little over 29 minutes!
