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.
Q: Premise: A small spark created a fire in the kitchen. 
 Initial Context: Smoke surrounded the entire room. 
 Original Ending: The alarm system detected the smoke. It triggered a response to release the sprinklers. The smoke and fire was eliminated. 
 Counterfactual Context: The smoke in the room subsided before the smoke alarm went off.
A: 
The alarm system failed to detect the smoke. It was supposed to trigger a response to release the sprinklers. The smoke and fire would then be eliminated.
