This question reminds me of my grad school and teaching days. Some people people feel that to make a challenging question, there has to be a semantic trick to the way the question is asked. This frequently occurs when the person asking the question is so sure of the answer that they fail to put themselves in the place of the person asked to answer the question. They don't see that the question is phrases in a possibly confusing manner. With a question like that, you're not testing subject knowledge, you're testing test taking skill. And, I might mention it places an extra burden on the nonnative speaker of the language - someone who is not as well equipped to ferret out the subtleties in the question.

Or, these questions can be developed by someone with a (hidden or not) sadistic streak that takes joy in the semantic trick itself.

To bad, as this has marred an otherwise good question that forced me to learn something I didn't know. Always good.
