Everyone sitting in the waiting room of the school’s athletic office this morning at nine o’clock had just registered for a beginners tennis clinic. John, Mary, and Teresa were all sitting in the waiting room this morning at nice o’clock. No accomplished tennis player would register for a beginners tennis clinic.

were the only people who registered for a beginners tennis clinic this morning. - WRONG. Like D only there can still be some more.

were the only people sitting in the waiting room of the school’s athletic office this morning at nine o’clock. - WRONG. Not the only people. There might still be some.
