Answer 1

Here are the statements categorized into the appropriate spaces:

1. **The sum of two nonzero rational numbers is rational.**
- **Always True**

2. **The sum of a nonzero rational number and an irrational number is rational.**
- **Never True**

3. **The product of two irrational numbers is irrational.**
- **Sometimes True** (e.g., the product of √2 and √2 is 2, which is rational, but the product of √2 and √3 is irrational)

4. **The product of a nonzero rational number and an irrational number is rational.**
- **Never True** (e.g., rational number times an irrational number is always irrational)

So, the final categorization looks like this:

- Blank space 4 (The sum of two nonzero rational numbers is rational): **Always True**
- Blank space 5 (The sum of a nonzero rational number and an irrational number is rational): **Never True**
- Blank space 6 (The product of two irrational numbers is irrational): **Sometimes True**
- Blank space 7 (The product of a nonzero rational number and an irrational number is rational): **Never True**
