The problematic ones are the "sensible answers" that sound very plausible, but are subtle wrong.

I once saw a LLM generated solution list of how to fix certain printing problems, and the 12 item list was totally fine for the first 6 or so items, to turn totally freaky destructively wrong from then on (as in replace hardware for an obvious software issue). These might even catch experts, as you don't always read the whole answer in detail.
