In the first test, the program execution starts with instruction $1$ setting $A$ to $1$. Then, instructions $2$~and~$3$ are executed in one of the two orders:
\begin{shortitems}
\item if ``\texttt{= 2}'' is executed before ``\texttt{+ 3}'', $A$ will be equal to $5$;
\item if ``\texttt{+ 3}'' is executed before ``\texttt{= 2}'', $A$ will be equal to $2$.
\end{shortitems}
Thus, there are two possible values of $A$ at the end: $5$ and $2$.
