(B) $1$. $A$ conditional statement $A 	o B$ is false only when $A$ is true $(T)$ and $B$ is false $(F)$.$2$. Here, $(p \land q) 	o (r \lor \sim s)$ is false, so $(p \land q) = T$ and $(r \lor \sim s) = F$.$3$. For $(p \land q) = T$, both $p$ and $q$ must be $T$.$4$. For $(r \lor \sim s) = F$, both $r$ and $\sim s$ must be $F$.$5$. Since $r = F$ and $\sim s = F$, it follows that $s = T$.$6$. Thus, the truth values are $p = T, q = T, r = F, s = T$.

The statement pattern $(p \land q) \to (r \lor \sim s)$ is false. Then the truth values of $p, q, r$ and $s$ are respectively
