premise: Male magician doing a trick in front of an audience.
hypothesis: A man is nervous about his magic show.
explanation_1: The present tense is made evident by the word "is" which is missing from the first sentence. There is no indicator that he is nervous. It is not clear whether he is doing a single trick or a show. A magician could perform a variety of shows as an alternative to a "magic" show specifically.
