## Identifying Equivalent and Equal Sets

### Pair of Sets

#### (a)
**Set Definitions:**
- \( A \) is the set of even numbers greater than 1 and less than 7.
- \( B \) is the set of integers greater than 15 and less than 19.

**Choice Options:**
1. ☐ Equivalent but not equal
2. ☐ Equal but not equivalent
3. ☐ Both equivalent and equal
4. ☐ Neither equivalent nor equal

#### (b)
**Set Definitions:**
- \( A \) is the set of integers greater than 20 and less than 24.
- \( B = \{21, 22, 23\} \)

**Choice Options:**
1. ☐ Equivalent but not equal
2. ☐ Equal but not equivalent
3. ☐ Both equivalent and equal
4. ☐ Neither equivalent nor equal

#### (c)
**Set Definitions:**
- \( A = \{73, 74, 75, 76\} \)
- \( B = \{21, 22, 23, 24\} \)

**Choice Options:**
1. ☐ Equivalent but not equal
2. ☐ Equal but not equivalent
3. ☐ Both equivalent and equal
4. ☐ Neither equivalent nor equal

#### (d)
**Set Definitions:**
- \( A = \{g, j, k\} \)
- \( B = \{n, p, q, r\} \)

**Choice Options:**
1. ☐ Equivalent but not equal
2. ☐ Equal but not equivalent
3. ☐ Both equivalent and equal
4. ☐ Neither equivalent nor equal

### Instructions
Select the best description that matches the relationship between each pair of sets.

### Notes on Definitions:
- **Equivalent sets:** Sets that have the same number of elements.
- **Equal sets:** Sets that have exactly the same elements.

### Example Explanation
No diagrams or graphs are present; the exercise consists solely of textual definitions and multiple-choice questions.
