At the grocery store, we    39   some apples --- red, green and yellow ones. Back home, I told Alice, “It’s time to    40   your question.” I put one apple of each    41   on the table. Then I looked at Alice, who had a    42   look on her face.

“Okay, Alice, tell me which is which.”

She totally    55   it. I didn’t need to say or do anything else.
