I could be wrong, but the question is ill-stated; should be something like 'which of the following statements are true', I think, or maybe 'what is the only true statement in the following list.' It's been awhile since logic classes though, maybe those are essentially the same as the original question, I can't quite figure out what I think is wrong with the original question, it just doesn't seem quite right to me. Also, 4 is ill-stated -- "One of the above is true" -- does that mean exactly one of the above is true, or at least one of the above is true. Although in that case I don't think it matters because 1/2 are mutually exclusive and 2/3 are mutually exclusive, and the combination of those two means that 1/3 are mutually exclusive., so only exactly one of 1-3 can possibly be true anyway.
