The correct Answer is:
To solve the problem, we need to analyze the statements given and determine their logical equivalences.
### Step-by-Step Solution:
1. **Identify the Statements**:
- Let \( p \): "x is an irrational number".
- Let \( q \): "y is a transcendental number".
- Let \( r \): "x is a rational number if y is a transcendental number".
2. **Expressing Statement \( r \)**:
- The statement \( r \) can be expressed in logical terms as:
\[
r: q \implies \neg p
\]
- This means if \( y \) is a transcendental number (i.e., \( q \) is true), then \( x \) must be a rational number (i.e., \( p \) is false).
3. **Understanding the Logical Equivalence**:
- The statement \( r \) can also be rewritten using the contrapositive:
\[
r: \neg p \implies \neg q
\]
- This means if \( x \) is not a rational number (i.e., \( x \) is irrational), then \( y \) is not a transcendental number.
4. **Analyzing Statement 1**:
- Statement 1 claims that \( r \) is equivalent to either \( p \) or \( q \):
\[
r \equiv p \lor q
\]
- This is incorrect because \( r \) does not imply that either \( p \) or \( q \) must be true; it states a conditional relationship.
5. **Analyzing Statement 2**:
- Statement 2 claims that \( r \) is equivalent to \( \neg p \iff \neg q \):
\[
r \equiv \neg p \iff \neg q
\]
- This is correct because it captures the logical relationship established in step 3.
6. **Conclusion**:
- Therefore, Statement 1 is false, and Statement 2 is true.
### Final Answer:
- Statement 1 is false, and Statement 2 is true.
