The correct Answer is:
To solve the problem, we need to analyze both statements given and determine their truth values. ### Step 1: Analyze Statement 1 The first statement is: \[ (p \rightarrow \neg q) \land (\neg q \rightarrow q) \] We need to determine if this statement is a contradiction. A contradiction is a statement that is always false. 1. **Construct a truth table** for the components of the statement: - Let \( p \) and \( q \) take values True (T) and False (F). - The implications \( p \rightarrow \neg q \) and \( \neg q \rightarrow q \) will be evaluated. | \( p \) | \( q \) | \( \neg q \) | \( p \rightarrow \neg q \) | \( \neg q \rightarrow q \) | \( (p \rightarrow \neg q) \land (\neg q \rightarrow q) \) | |---------|---------|---------------|-----------------------------|-----------------------------|----------------------------------------------------------| | T | T | F | F | T | F | | T | F | T | T | F | F | | F | T | F | T | T | T | | F | F | T | T | F | F | From the truth table, we see that the expression \( (p \rightarrow \neg q) \land (\neg q \rightarrow q) \) is false for all combinations of \( p \) and \( q \) except when \( p \) is false and \( q \) is true. Therefore, Statement 1 is not a contradiction since it can be true in some cases. ### Step 2: Analyze Statement 2 The second statement is: \[ \text{The inverse of } (p \rightarrow \neg p) \text{ is } (\neg p \rightarrow p) \] 1. **Understanding the inverse**: - The inverse of an implication \( A \rightarrow B \) is \( \neg A \rightarrow \neg B \). - Here, \( A \) is \( p \) and \( B \) is \( \neg p \). - Therefore, the inverse of \( p \rightarrow \neg p \) is \( \neg p \rightarrow p \). 2. **Evaluate the truth of the inverse**: - The statement \( p \rightarrow \neg p \) is a contradiction because if \( p \) is true, \( \neg p \) is false, making the implication false. - The inverse \( \neg p \rightarrow p \) is not a contradiction. It can be true when \( p \) is false. ### Conclusion - Statement 1 is false (not a contradiction). - Statement 2 is true (the inverse is correctly stated). Thus, the correct answer is that Statement 1 is false and Statement 2 is true. ### Final Answer - **Statement 1**: False - **Statement 2**: True
