**Multiple Choice**

A directed graph \( G \) has 5 vertices, numbered 1 through 5. The 5x5 matrix \( A \) is the adjacency matrix for \( G \). The matrix \( A^2 \) is given below.

\[ A^2 = \begin{pmatrix} 
0 & 0 & 1 & 0 & 0 \\ 
0 & 0 & 0 & 0 & 0 \\ 
0 & 0 & 0 & 0 & 1 \\ 
1 & 0 & 1 & 0 & 0 \\ 
0 & 0 & 1 & 0 & 1 
\end{pmatrix} \]

Which vertex can be reached by a walk of length 4 that starts at vertex 1?

- ○ 2
- ○ 5
- ○ 3
- ○ 4
