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? If you are still confused, see the following example:
Premise: Susie was sitting on her barstool. 
 Initial Context: She kept kicking the counter with her feet. 
 Original Ending: Suddenly, her kick sent her falling backwards. The chair hit the ground with a thud and broke. Susie hurt her head and was really scared. 
 Counterfactual Context: She kept herself steady with her feet.
Solution: Suddenly, an earthquake sent her falling backwards. The chair hit the ground with a thud and broke. Susie hurt her head and was really scared.
Reason: The generated new ending is perfect. It considers the counterfactual context and changes required parts in original ending.

Now, solve this instance: Premise: The Celtics had a mediocre basketball team. 
 Initial Context: During the off-season they decided to make big changes. 
 Original Ending: They picked up a a few up and coming athletes from college. The owners were happy with the management's decisions. The Celtics had a winning record the following season. 
 Counterfactual Context: During the off-season they decided against any big changes.
Student:
They picked no up and coming athletes from college. The owners were happy with the management's decisions. The Celtics had a winning record the following season.
