Answer:
A phrase is an oxymoron if and only if it contains contradictory terms.

A conditional statement is a statement written in the "if-then" form.
The converse of a conditional statement is when the hypothesis and the conclusion is interchanged.
A biconditional statement is a combination of a conditional statement and its converse written in the "if and only if" form.
