Given the matrix $A$ below, use the extended echelon form of $A$ to answer each part of this problem. In each part, find a linearly independent set of vectors, $S$, so that the span of $S$, $\spn{S}$, equals the specified set of vectors. \begin{equation*} A= \begin{bmatrix} -5 & 3 & -1 \\ -1 & 1 & 1 \\ -8 & 5 & -1 \\ 3 & -2 & 0 \end{bmatrix} \end{equation*}

1. The row space of $A$, $\rsp{A}$.
2. The column space of $A$, $\csp{A}$.
3. The null space of $A$, $\nsp{A}$.
4. The left null space of $A$, $\lns{A}$.
