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.

Premise: The Big Bang Theory predicted background radiation in the sky. 
 Initial Context: The radiation should be strongest at microwave wavelengths. 
 Original Ending: Two Bell Lab scientists detected such a signal in 1964. They cleaned the antenna of pigeon droppings to be sure it was real. The Bell Lab scientists shared a Nobel Prize for their discovery. 
 Counterfactual Context: The radiation should be strongest at microwave wavelengths, but was unable to be detected.
Two Bell Lab scientists tried their best to detect such a signal in 1964. They failed and tried other ways of detection. The Bell Lab scientists would have loved to share a Nobel Prize for a discovery.
