> I have no idea what "the number of this sentence" or "the letter of this sentence" even means. But then you can't believe it has two answers. If you don't understand the question you can't make any claims about it except maybe that you believe it is incoherent. As alexey-salmin says, the only reasonable interpretation is to circle the 1. to left of the question. To claim that has 2 answers is similar to claiming a "Find x" style question has two answers (solving an equation vs. circling x). No, the question only has one reasonable interpretation. If the examiner is being unreasonable it is not a problem with the question and not something that can be deduced by examining the question.
