Do you think all the seven questions have the same answer? If you think so, then, whether the same answer is A, B, or both of them, there is a consistency in the usage of ‘until’, which is easy to understand, I think.

Even if you don’t think all the questions have the same answer, it’s not a problem for me. As long as all of you give me the SAME RESULT (for example, if all of you insist that the answers to Q1~Q5 are B but the answers to Q6~Q7 are A), then the same consistent result verifies that there is a consistency in the usage of ‘until’.

However, if each of you have different opinion on the answers, and, as a result of that, there come several different results, this is a big problem for me because it’s really hard to understand the complicated usage of ‘until’.
