Solution
A biconditional statement is the conjunction of two conditional statements.

A biconditional statement (p ⇔ q) means that p is true if and only if q is true. This is equivalent to the conjunction of two conditional statements: p ⇒ q and q ⇒ p. Both conditions must hold true for the biconditional to be true.
