Teacher:In this task, you're given four sentences of a story written in natural language in which one part is missing. Your job is to predict the position and missing part of the story and return in the following format: position, missing part. The missing part is a sentence that completes the story, and the position is the number of the missing sentence in the new story.
Teacher: Now, understand the problem? Solve this instance: Sentence1: She found out her company wanted her to retire. Sentence2: Although she has a good pension, she was still nervous. Sentence3: I helped her rewrite her resume, preparing for a job search. Sentence4: Sharon is now looking forward to a new chapter in her life.
