**Solve the Problem**

Suppose there are 8 roads connecting town A to town B and 4 roads connecting town B to town C. In how many ways can a person travel from A to C via B?

- ○ 32 ways
- ○ 64 ways
- ○ 12 ways
- ○ 16 ways

**Explanation:**

To determine the number of ways a person can travel from town A to town C via town B, we need to consider the separate routes between each segment:

1. **From A to B:** There are 8 roads available.
2. **From B to C:** There are 4 roads available.

To find the total number of ways to travel from A to C via B, multiply the number of ways for each segment:

\[ \text{Total ways} = 8 \times 4 = 32 \]

Therefore, the correct answer is 32 ways.
