Instructions: 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.
Input: Premise: Tia was staying late at work. 
 Initial Context: It took her a long time to get caught up on her work.

 New ending: By the time she left, the parking lot was pretty full. It was welcoming and well lit. Tia had to ask the security guard to walk her to her car anyway. 
Output:
It took her a short time to get caught up on her work.
