Don't smoke in the meeting-room, __? (A) do you (B) will you (C) can you (D) could you The answer is option B. Is option C also acceptable? No, C is not a natural response.
However, you'll occasionally hear it in the negative form. eg Put that cigarette out, can't you? It conveys a sense of exasperation here.
(B) seems like the best of a bad lot. I don't find any of them natural. My choices would be (E) okay?; (F) would you not?; (G) can you not?; (H) could you not?
Hi, However, you'll occasionally hear it in the negative form. eg Put that cigarette out, can't you? It conveys a sense of exasperation here.
When I said this, I didn't think it necessay to point out that the preceding statement (as marked in pink in the example) had to be positive. Perhaps I should have.
