Find someone who speaks better English to help me solve the following questions, thank you!

1.D Good morning! Good morning! (As mentioned in the first paragraph, when meeting foreign friends for the first time, we do not ask them questions about their private life. so we may talk about THE WEATHER) When meeting foreign friends for the first time, we do not ask about their private life, but about the weather and sports. And so on

2.A Good night! Good night! (Good night is usually said before going to bed. When meeting friends at night, I only say Good evening!)

3.C I'm fine thank you! I'm fine thank you! (The other three are greetings)

4.B Are you married? Are you married? (Don’t ask about your personal life when you meet for the first time!)

5.A Shake hands (the article does not mention smiling at each other)

Hope it is helpful to you! :D
