To solve the equation \( 33 \_ 3 \_ 2 \_ 5 = 1 \), we need to determine the correct mathematical operations (like \( + \), \( - \), \( \times \), or \( \div \)) to place in the blanks.

Let's test different combinations:

1. **Division and subtraction**:  
   \[
   \frac{33}{3} - 2 - 5 = 11 - 2 - 5 = 4 \quad \text{(Not equal to 1)}
   \]

2. **Subtraction and division**:  
   \[
   33 - \frac{3}{2} - 5 \quad \text{(this gives a fraction, not 1)}
   \]

3. **Subtraction and division**:  
   \[
   33 - 3 - 2 \div 5 \quad \text{(still not equal to 1)}
   \]

4. **Division, division, and division**:
   \[
   \frac{33}{3} \div 2 \div 5 = \frac{11}{10} = 1.1 \quad \text{(close, but not 1)}
   \]

5. **Subtraction and division**:
   \[
   33 - 3 \div 2 - 5 \quad \text{(still not equal to 1)}
   \]

6. **Subtraction, division, subtraction**:
   \[
   33 - \left(\frac{3}{2}\right) - 5 = 33 - 1.5 - 5 = 26.5 \quad \text{(not equal to 1)}
   \]

7. **Division, division, and subtraction**:
   \[
   \frac{33}{(3 \times 5)} - 2 = \frac{33}{15} - 2 \quad \text{(not 1)}
   \]

None of these simple operations alone work. However, adding brackets or using operations with appropriate order might yield the solution.

- **Consider using subtraction, division, and addition/subtraction**:
   \[
   33 - 3 \times (2 + 5) = 33 - 21 = 12 \quad \text{(Not 1, but let’s try more combinations)}
   \]

Let's simplify it more:
   \[
   \frac{33 - 3 \times 2}{5} = 1
   \]
  This isn't 1.

After several trials:

Correct interpretation should be:
\[
33 \div 3 - 11 + 2 - 2 = 1
\]
