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.

 Initial Context: The mother duck was trying to cross at an inconvenient spot. 
 Original Ending: A nice cop stopped traffic to escort the ducklings. After a few minutes, the mother and her ducklings made it across. Everyone cheered for the cop from their cars. 
 Counterfactual Context: The mother duck was ran over trying to cross at an inconvenient spot.
A nice cop stopped traffic to pick up the dead mother duck and escort the other ducklings to safety. After a few minutes, the surviving ducklings made it across. Everyone cheered for the cop from their cars.
