Now Joe is symbolizing his thoughtsputting his thoughts into words. In answer to the question What do you mean? Joes is now trying to rememberrhe is now trying to clarify his thoughts about the moon.
But there is still a third emphasis, a third way to answer the question. Joe may be a hardheaded reporter.
