M: Hey, Charlie, do you want to come to my house after school and play video games with me? I just got a cool new game. We will go pick up my dad at the airport at 6:00 but you can stay for 2 hours.
(A) F: Ok. Since you will pick up your dad at four, I can stay for 3 hours. (B) F: I’m sorry, I don’t understand. Could you say it again? (C) F: No problem. Please remember to pick up your dad at six. Do not be late. (D) F: Of course. We will pick up your dad at the bus station at two.
