W: John, my dad's new MP3 player seems to be missing. Did you move it? M: No, I didn't. Isn't it right next to the computer? W: No, and I don't see it anywhere. I have the feeling one of our party guests took it. M: Really? What are you going to do now? W: I'll just tell my parents what happened, I guess. M: Then they'll know you had people over without permission. Won't they be angry about that? W: Probably. I wish I'd done that from the start, instead of keeping my plans secret. They'd have said no to a party, and the MP3 player would still be here., Question: What did the girl regret? (A) Not telling her parents about the party. (B) Not keeping her plans secret. (C) Not keeping tile MP3 player well.
(A) Not telling her parents about the party.
