Find a second suitable matrix for equation

Given the matrix:

$$\begin{pmatrix} 0 & 0 & 1 & 1\\ -2 & 2 & 3 & -3\\ 1 & -1 & -2 & 1 \\ \end{pmatrix}$$

1. Find an invertible matrix P and a Reduced row echelon form matrix D such that: $PA = D$
2. Find a bases for $ColA$
3. Find a second matrix $Q$ that: $P\neq Q$ and $QA = D$

I've managed to solve questions 1: $$D = \begin{pmatrix} 1 & -1 & 0 & 3\\ 0 & 0 & 1 & 1\\ 0 & 0 & 0 & 0 \\ \end{pmatrix} , P = \begin{pmatrix} 0 & -2 & -3\\ 0 & -1 & -2\\ 1 & 1 & 2 \\ \end{pmatrix}$$

and question 2: $$\begin{bmatrix} 0 \\ 2 \\ 1 \\ \end{bmatrix}, \begin{bmatrix} 1 \\ 3 \\ -2 \\ \end{bmatrix}$$

But I don't know how to solve question 3.

$Q = A^{-1}D$
