Task: Story Composition
Input (English): 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.
Output (English): 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.
