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.
Explanation : There are two main categories of tests:
Maximum Performance Tests & Typical
Response Tests. Typical performance
is how one performs on a regular basis,
while maximum performance is how one
performs when exerting as much effort as
possible. Maximum Performance Tests are
designed to test a persons' knowledge and
abilities. These are: intelligence, aptitude
& achievement tests. Personality tests and
attitude tests.
