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: Dan went on a fishing trip to Lake Erie. 
 Initial Context: He went out on the lake in his boat. 
 Original Ending: He casted out his fishing pole and waited. A fish grabbed his bait he lost his fishing pole. He gave up on fishing and went home. 
 Counterfactual Context: He went out on the lake in his boat but forgot his pole.
Student:
He fashioned a make-shit pole from an oar and waited. A fish grabbed his bait and pulled the oar down with it. He gave up on fishing and slowly paddled home.
