(A) M: Just a minute! I do not quite follow what you are saying, would you mind repeating that? (B) M: Okay, that's prefect price with a lunch included, which means I just need to spend 50 pounds to travel all these places.

(D) M: Alright, it's great that the price include tea at 9:50 am and 5:30 pm, I'll pay for the 60 pounds by my credit card.
