### Question 2

**Let the Universal set be the letters a through j:**
\[ U = \{a, b, \ldots, i, j\} \]

**Let \( A = \{ b, c, f, g \} \), \( B = \{ a, c, e, g \} \), and \( C = \{ b, e, g, i \} \)**

**List the elements of the set \( A \cap (B \cup C) \)**:

---

**Analysis:**

1. **Determine the Union \( B \cup C \):**
   \[ B \cup C = \{ a, c, e, g \} \cup \{ b, e, g, i \} \]
   Combining all unique elements, we obtain:
   \[ B \cup C = \{ a, b, c, e, g, i \} \]

2. **Find the Intersection \( A \cap (B \cup C) \):**
   \[ A = \{ b, c, f, g \} \]
   Compare with \( B \cup C \):
   \[ A \cap (B \cup C) = \{ b, c, f, g \} \cap \{ a, b, c, e, g, i \} \]
   
   The common elements are:
   \[ A \cap (B \cup C) = \{ b, c, g \} \]

**Answer: \(\{ b, c, g \}\)**
