### Step 1: Understand the Assertion
The assertion states that "Acrylic fabrics are used in making socks and shawls."

### Step 2: Understand the Reason
The reason states that "Acrylic fabrics are a replacement for wool."
- **Explanation**: Acrylic fibers are often used as a substitute for wool because they can mimic the properties of wool, such as warmth and softness, while being more affordable and easier to care for. This makes them a popular choice for consumers looking for wool-like products without the higher cost.

### Step 3: Evaluate the Relationship
Now, we need to evaluate the relationship between the assertion and the reason.
- Both statements are true. Acrylic fabrics are indeed used in making socks and shawls, and they serve as a replacement for wool due to their similar properties and lower cost.
