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

If the truth value of the expression $[(p \vee q) \wedge (q$ $\rightarrow r) \wedge (\sim r)]$ $\rightarrow (p \wedge q)$ is False,then the truth values of $p, q, r$ are respectively:

The negation of $(p \wedge q) \rightarrow (\sim p \vee r)$ is

The proposition $p \Rightarrow \sim (p \wedge \sim q)$ is

The statement $[p \wedge (q \vee r)] \vee [\sim r \wedge \sim q \wedge p]$ is equivalent to

The contrapositive of $(p \vee q) \Rightarrow r$ is
