Umiejeś citat' i pisat' po-russki? :-)
Why is the answer: "Are you able to read and write" not accepted. I know it is a bit more formal than "Can you" or "Do you know how to", but is there some specific reason this answer is not accepted?
It's accepted, it should have worked.
What about: "Do you can read and write?" ?
Yeah, I'm afraid that's not really English...
Can you read and write?
Can is an auxiliary verb which mean it can (heh) switch places with the subject (something non-auxiliary verbs can't), so there's no need for do.
