Input: M: I want to book a bus tour for the middle of June. ,F: Well, we have red and blue routes. The main attractions on the red route are the White House, the Lincoln Memorial and the Smithsonian Museum. ,M: How do I book the tickets? ,F: Well, you could do that by phone with one of our operators, or you can book through our website. Of course, you could just show up and buy a ticket the day you want to take the tour. ,M: Alright. I'll just book it online once I know our travel dates. ,F: OK, well, just remember that it can get very busy over the three months from June to August. So it's probably best to book at least a week before you come, but you still have about 6 weeks. So you have plenty of time to think about it.
(A) M: Ok, I will call you later to buy my ticket. Thank you for introducing train tour to me. (B) M: It's a good idea to buy the ticket on the bus, because it's not busy from June to August. (C) M: I have only 6 days to think about it, so I will buy my ticket online as soon as possible. (D) M: I’m sorry, I don’t understand. Could you say it again?
