Humans also generate something that sounds like it would answer the prompt. If I ask you "What country is Machu Picchu in?", you'll ponder for a moment, and give me what you think the answer to the prompt is. You might answer Peru, or you might answer with something else that seems reasonable to you, like Argentina.
Humans answer questions incorrectly all the time. And they also try to come up with a reasonable response to prompts when questioned.
