Input: M: Oh, hello, I like the holiday that mentioned Whales, was it whale watching? ,F: Oh yes, it's very popular. ,M: How long does it last? ,F: 2 days. We take up to 15 people on this tour, though we usually run it with just 12 or 13. ,M: And when is the next tour going? ,F: Umm, there is one in 3 weeks time on April the eighteenth and then we don't have another one until June the second. ,M: Is there anything else included in the tour? ,F: Oh, there are a lot of things. If you don't want to do the whale watching cruise, your guide will take anyone who is interested. In a Bush walk through the National Park near the hotel. There is no extra charge for that or on a fishing trip, which is an extra $12 I think. There is also a reptile park in town, which costs more or less the same.
(A) M: So the reptile park cost no extra money, isn't it? (B) M: Oh, we don't need to spend extra money on bush walk. (C) M: Oh, the fishing trip cost no extra money. That's great. (D) M: Just a minute! I do not quite follow what you are saying, would you mind repeating that?
