Imagine a question and stream-of-consciousness explanation for which this is the answer: it is not possible to tell
Question: Given the sentence "An older man is trying to figure out what a sewing machine is." is it true that "The gentleman wants to learn how to use a sewing machine."?
Stream-of-consciousness: Not every older man is a gentleman. Just because the man is trying to figure out what a sewing machine is does not mean that he wants to learn how to use it.
