The Boolean expression $(\sim(p \wedge q)) \vee q$ is equivalent to

If $p$ and $q$ are true and $r$ and $s$ are false statements,then which of the following is true?

If $p \rightarrow (p \wedge \neg q)$ is false,then the truth values of $p$ and $q$ are respectively

Show that the statement "For any real numbers $a$ and $b$,$a^{2}=b^{2}$ implies that $a=b$" is not true by giving a counter-example.

Consider the following statements:
Statement $I$: If a quadrilateral $ABCD$ is a square,then all of its sides are equal.
Statement $II$: If all the sides of a quadrilateral $ABCD$ are equal,then $ABCD$ is a square.
Then:

Let $p$ and $q$ be two statements. Amongst the following,the statement that is equivalent to $p \to q$ is
