Well, I won't argue the merits of chucking an entire exam because one question is farked, but the clanger question issue is also a problem with the HSK, or Chinese version of the JLPT.
Having two correct answers out of four with one 'more correct' than the other is bollocks; to paraphrase Orwell, "all answers are potentially correct, but some answers are more correct than others."
In the end, on the advice of my tutor I had to go with three categories:
1) obviously wrong answers
2) answers that are logically or rationally defensible
3) answers that are correct 'for test purposes only'
