the details of this excerpt reveal the author’s purpose by
explaining why the fans acted like they did.
including facts and details about the topic.
expressing opinions about a topic.
encouraging the reader to believe in something.

Explanation:

The excerpt provides factual details about Neto's experience with racial insults, Andy's reaction, and their teamwork. The option "including facts and details about the topic" matches as the author is presenting factual information (like Neto's role, the insults, Andy's involvement) to reveal the purpose. The other options: "explaining why fans acted" – the excerpt doesn't explain the fans' motives; "expressing opinions" – it's factual, not opinion - based; "encouraging belief" – the excerpt is descriptive, not persuasive to encourage belief.

Answer:

including facts and details about the topic.
