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? Solve this instance: Premise: The captain of the new steamship wanted to  test it out. 
 Initial Context: He commanded the engine crew to go full steam. 
 Original Ending: The ship sailed across the sea faster than anyone ever went. The captain then commanded a hard turning maneuver. The boat tilted hard but performed admirably throughout. 
 Counterfactual Context: He pleaded the engine crew to go no steam.
Student:
With the captain's odd idea, the ship sailed across the sea faster than anyone ever went. The captain then commanded a hard turning maneuver. The boat tilted hard but performed admirably throughout.
