What do you think the right answers are?

If I knew the answers, I woundn't come here asking you teachers

[Anglika]

You must realise that we provide guidance and advice, but do expect people to show that they have at least tried to do the work. If you indicate what you think the answers should be, someone will comment.

(1) You must be a doctor,______?
A. aren't you?? B. mustn't you? C. are you?

Choose one, and I'll tell you why you are wrong.

I understand this is not a place for helping students do their homework. But the thing is, this one is actually not an assignment. I myself came up with them. Just trying to do it as extracurricula excercise in preparation of our final test.

I'm not native speaker so my questions are probably not even valid. I just have problem with tags, especially with how to use them after modal verbs....And I've asked same batch of questions from other native English speakers. Sadly, each of them gave me a different set of answers.....that's why I'm here

[RonBee]

Well, that was a nonresponsive response. Let's look at number one anyhow.

(1) You must be a doctor,______?
A. aren't you?? B. mustn't you? C. are you?

Real life possibilities:

You are a doctor, aren't you?
You seem to be a doctor. Are you?

Any comments or questions?

What do you suggest for a different title for this thread? Exercises?
