Final answer:
The two sentences that describe the exposition and conclusion of the plot in the story are (c) the coach explained the system he used to reveal who made the team and (d) Jonathan opened his envelope to discover that he did not make the team.
Step-by-step explanation:
The question asks to choose two sentences that describe the exposition and the conclusion of the plot in a story. The exposition is the part of a story that sets the scene, introduces the characters, and provides background information. The conclusion is the section of the plot that resolves the conflict and ties up loose ends, often after the climax of the story.
In the context provided, sentence (c) "the coach explained the system he used to reveal who made the team" serves as part of the exposition because it provides background information on how decisions are communicated in the story. Sentence (d) "jonathan opened his envelope to discover that he did not make the team" can be seen as part of the conclusion because it reveals the outcome for Jonathan, which is a resolution of sorts.
