The compound statement \( (p \lor Q) \land (\sim p) \Rightarrow Q \) is equivalent to:
\( \sim (p \Rightarrow Q) \)
\( p \land \sim Q \)
\( p \lor Q \)
\( \sim (p \Rightarrow q) \Leftrightarrow p \land \sim q \)
Consider the two statements:\( \text{(S1)}: (p \to q) \vee (\sim q \to p) \) is a tautology.\( \text{(S2)}: (p \wedge \sim q) \wedge (\sim p \vee q) \) is a fallacy.Then:
