For me, that kind of comes under the category of "know how to answer the question": that is, "remember that you have produced an example, which does not constitute proof but merely evidence". You're right that it's still not easy to distinguish between "definitely yes" and "not {definitely no}", though I do still find it easier with nouns-which-I-know than made-up-words, I think. I should have put in an attempt to make the statement true - maybe "Given that all cats are cats, and some cats are cats, are all cats cats?"
