Explanation : Two events (or propositions) are mutually
exclusive or disjoint if they cannot both
occur at the same time.
It is of course true that if a teacher
wants to improve his or her abilities as
an effective classroom communicator,
he or she should first understand the
students. And to understand them, it is
imperative to listen effectively to their
messages. So, understanding students
and intended listening are not disjointed
propositions.
