You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
In this task, you will be shown a conversation and a question. You need to write an implausible answer to the question. Even though there exist multiple wrong answers, we only need a single wrong answer. "W" and "M" in the conversations stand for "woman" and "man".

M: I am considering dropping my dancing class. I am not making any progress. W: If I were you, I stick with it. It's definitely worth time and effort., Question: What does the man suggest the woman do?
Solution: Take a more interesting class.
Why? This is a good example. Based on the conversation, the man thinks the dancing class is worth time and effort. So, the man doesn't suggest her to take a more interesting class and one of the wrong answers is "Take a more interesting class.".

New input: M: I think we'd better go over my schedule, Irene. I'm going to have a look at our European operation, as you know, and as I'll be visiting a number of countries, I'd like you to make the bookings. W: Right, Mr Buck. I'll take down the details. M: Well, I'm leaving on Tuesday, April 15th, for London. I'm going to attend a sales conference for our British representatives. That runs through Wednesday and Thursday, and then there's a reception at Canada House on Thursday evening. W: Are you going to meet the Ambassador, then? M: I guess so. But the main thing is that on Friday morning, I have a meeting with the British Minister of Trade and Industry. We're going to discuss the site of our new plant in Scotland. W: So when are you leaving for Paris? M: First flight on Saturday morning. I'm planning to meet my wife there. She's going to fly over direct, arriving in the afternoon. Then we'll have a relaxed weekend before I see Mr Chambery, the European Manager, on Monday. So from Paris on, I'll need a double room. W: How long are you going to stay in Paris, Mr Buck? M: Only till Monday evening. I'm going to Rome to see our plant there on Tuesday, and on Wednesday I'm due in Madrid to inspect the new factory. W: And that's the last item on the agenda. So when are you coming back? Are you going to fly from Madrid? M: Yes, on the first plane out on Thursday. We must be back on Friday, the 25th. It's my daughter Sharon's birthday., Question: How long will the sales conference in London last?
