Find the intersection of each pair of sets of question 1 above.

Explanation

To find the intersection of each pair of sets, we will follow these steps:

### Step 1: Identify the Sets
Let's denote the sets as follows:
1. Set \( X = \{1, 2, 3, 5\} \)
2. Set \( Y = \{1, 3, 4\} \)
3. Set \( A = \{x | x \text{ is a natural number and } x \text{ is a multiple of } 3\} \)
4. Set \( B = \{x | x \text{ is a natural number and } x < 6\} \)
