Given the task definition, example input & output, solve the new input case.
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.
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.
Output: 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.
The generated new ending is perfect. It considers the counterfactual context and changes required parts in original ending.

New input case for you: Premise: Joe was feeling a bit sick. 
 Initial Context: He attributed his sickness to the Chinese food he ate last night. 
 Original Ending: Joe clutched his stomach in pain. He called the ambulance to bring him to the hospital. The doctors confirmed that Joe had food poisoning at the hospital. 
 Counterfactual Context: He caught the stomach flu from his girlfriend.
Output:
Joe clutched his stomach in pain. He called the ambulance to bring him to the hospital. The doctors confirmed that Joe had the stomach flu at the hospital.
