premise: Person sitting at a desk in a library.
hypothesis: There is a man wearing glasses reading a book at the library.
explanation_1: The person is not identified by gender, so we do not know that he is a man. Although it is fairly common for a person to be wearing glasses while reading a book in a library, we have no information to indicate this.
