A properly _standardised_ test should at least have been administered to enough people that you were in the minority of the kind of people it was standardised against. Actually, a properly standardised test should have discarded questions like that if their answers weren’t reliable. In any case, it is quite unlikely that the test you took could reliably distinguish between scores above 145.
