Answer:
1. Are you tired?
2. Do you speak Russian?
3. Must you go now?
4. Can Sam swim?
5. Has he been to Poland?
6. Do you go to work by bus?
Step-by-step explanation:
By checking the grammar and playing a little game of subtracting by adding, finding the answers to these are quite easy. For clarity, here's an example of what I did so you know what to do next time:
On number 1, we are given three options: "Do you tired?" "Are you tired?" "Do you are tired?"
Well, either you say it out loud and ask yourself if that makes sense or you think that question.
Nobody says "do you tired," so that's off the list.
Nobody says "do you are tired," which makes just as much sense as the one before it.
That leaves us with "Are you tired," which sounds grammatically correct.
Hope this helped!
