Summary
A professor at a small university with a well-known choir concluded that none of the students who live off campus is a music major. Why? Because all music majors are members of the school’s choir.
Missing Connection
Based on the argument’s premise, we only know that if you’re a music major, you’re a member of the school’s choir. So why does the professor conclude that none of the students who live off campus is a music major?
The professor’s conclusion follows logically if we assume that all students who live off campus aren’t choir members. (Contrapositive: if you’re a choir member, you don’t live off campus).
