premise: A female and two males in a classroom. hypothesis: A girl and two boys in class with two teachers.
neutral: It is possible that students can be in a classroom without two teachers being present. We do not know the ages of the people. Therefore, we cannot infer the terms 'girl' or 'boys'. Gender and sexuality are two separate entities. Just because the people are biologically male or female does not mean they identify as a 'girl' or a 'boys'.
