**Question 18A. Define the sets A and B as shown. Select all statements which are true.**

The image depicts a Venn diagram consisting of two sets, A and B, which overlap. The elements in each region of the diagram are as follows:

- **Set A (Left Circle):**  
  - Exclusive to A: c, w, p
  - Shared with B: a, s, m

- **Set B (Right Circle):**
  - Exclusive to B: g, f, h
  - Shared with A: a, s, m

**Statements:**

1. \(\{a, g, s, m\} \subseteq A\)
2. \(\{a, f, g, h, m, s\} \subseteq B\)
3. \(\{a, c, m, p, s, w\} \subseteq A\)
4. \(\{m, s\} \subseteq A\)
5. \(\{a, f\} \subseteq B\)

**Q17B. Define the sets A, B, C, and D as shown. Find \( A \cup (B \cap D) \).**

**Diagram Explanation:**

The Venn diagram consists of four sets, labeled A, B, C, and D.

- **Set A** includes: c, w, s, m
- **Set B** includes: p, a, g, f, h
- **Set C** includes: s, m
- **Set D** includes: a, g

The Venn diagram visually shows the overlap and unique elements of these sets. 

To solve **\( A \cup (B \cap D) \):**

1. **B ∩ D** (intersection of B and D) includes elements common to both B and D: a, g

2. **A ∪ (B ∩ D)** (union of A and the intersection of B and D) includes all elements in A or in the intersection of B and D: 

\{a, c, g, m, s, w\}

**Note:**

- Express the set using roster notation with letters ordered alphabetically, such as \{d, n, x, z\}.
- Braces and commas are required, with a space after each comma.
