If $p, q, r$ are simple propositions with truth values $T, F, T$ respectively, then which of the following is not a true statement?

Write the negation of the following statement:
Every natural number is an integer.

The statement $(p \wedge (p$ $\rightarrow q) \wedge (q$ $\rightarrow r))$ $\rightarrow r$ is :

Given the statement: "If you live in Delhi,then you have winter clothes."
Identify the following statements as contrapositive or converse of the given statement:
$(i)$ If you do not have winter clothes,then you do not live in Delhi.
$(ii)$ If you have winter clothes,then you live in Delhi.

Let the operations $*, \odot \in \{\wedge, \vee\}$. If $(p * q) \odot (p \odot \sim q)$ is a tautology,then the ordered pair $(*, \odot)$ is:

Consider the following statements:
$r$: If $p \to q$ is false then $p \lor q$ is false.
$s$: If $p \leftrightarrow q$ is false then $p \lor q$ is false.
The truth values of $r \to s$ and $s \to r$ are respectively . . . . . .
