	\item The tiler wants to be able to predict what tile will go in any position on the grid. For example, he wants to know what tile he will use in the marked position $(m; n)$.
	
	Study the tiling pattern and in particular the four tiles highlighted with a red border. Select ALL of the rules below that will correctly predict the tile that is needed for any grid position $(m; n)$.

\begin{enumerate}
    \item If $m + n$ is odd use tile~A, otherwise use tile~B.
    \item If $m + n$ is even use tile~A, otherwise use tile~B.
    \item If $m \times n$ is odd use tile~A, otherwise use tile~B.
    \item If $m \times n$ is even use tile~A, otherwise use tile~B.
    \item If $m$ is odd and $n$ is odd use tile~A, otherwise use tile~B.
    \item If $m$ and $n$ are both odd or both even use tile~A, otherwise use tile~B.
