You are given a conversation between two people. 'Person1:' and 'Person2:' are used to separate their respective dialogues. If the conversation begins with a question, label it '1' otherwise '0'.

Let me give you an example: Person1: Passport , please , madam .
Person2: Just a minute , please . It's in my bag . Here it is .
Person1: Thank you . Please fill out the Baggage Declaration Form .
Person2: All right . Shall I enter all my belongings ?
Person1: No , only the articles listed on the Declaration .
The answer to this example can be: 0
Here is why: The first sentence in the conversation begins with a request, therefore there is no presence of a question.

OK. solve this:
Person1: Beautiful weather , isn ' t it ?
Person2: Yes , it is . Are you here on business ?
Person1: No , I ' m on a vacation to see the famous Three Gorges .
Person2: I ' m going there for a tour , too . Is this your first trip to China ?
Person1: Yes , it is .
Person2: Why don ' t we go together ? I can show you around . I think you ' ll have a better time .
Person1: I couldn ' t agree more .
Person2: Great , let ' s go !
