Which of the following is not a statement?

The contrapositive of the statement: "If the weather is fine then my friends will come and we go for a picnic." is

If the truth value of the statement pattern $(\sim p \land q) \lor (\sim p \land \sim q) \lor (p \land \sim q)$ is $F$, then the truth values of $(p \lor \sim q)$ and $(p \to q)$ are respectively.

Find the component statements of the following and check whether they are true or not.
$\sqrt{2}$ is a rational number or an irrational number.

The symbolic form of the following circuit is (where $p$ and $q$ represent switches $S_{1}$ and $S_{2}$ being closed respectively):

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