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.
One example is below.
Q: Premise: Brad stole the ball from the opponent. 
 Initial Context: While he was running with the ball, he noticed his friend. 
 Original Ending: He threw the ball in the air, near the hoop. His friend grabbed the ball and made a drunk. That score put his team in the lead. 
 New ending: He stopped dancing and threw the ball in the air, near the hoop. His friend grabbed the ball and made a drunk. That score put his team in the lead.
A: While he was dancing with the ball, he noticed his friend.
Rationale: The answer is well in context with new ending and it is counterfactual to initial context.
