You're being silly. Why are "answer the question as stated" or "deconstruct the person's entire life to find their ultimate problem" the only logically consistent possible courses of action?
If someone asks a question that suggests something might have been misunderstood, there's nothing wrong with probing a little to find the reason for the question. Maybe the person really does know something you didn't, but it's much more likely that by asking clarifying questions you'll save theirs and your own time.
