You must load the following packages after automultiplechoice : fancyvrb, fancybox, pstricks, minted.
To use PSTricks, you have to configure AMC : → → → →
From wiki.
The verbatim environment interferes with AMC LaTeX package, so that it is impossible to use it inside question or questionmult environments... As an example, the following code won't compile:
\begin{question}{program}
What is the return value of the following R code?
\begin{verbatim}
sum(sapply(1:2^2,function(x) { x/2 }))
\end{verbatim}
\begin{choices}[o]
\wrongchoice{2.5}
\correctchoice{5}
\wrongchoice{NaN}
\end{choices}
\end{question}
For very small texts, it is possible to escape all characters that have a special meaning for LaTeX. However, this can become quickly tedious.
\begin{question}{program}
What is the return value of the following R code?
\begin{center}
\texttt{sum(sapply(1:2\textasciicircum 2,function(x) \{ x/2 \}))}
\end{center}
\begin{choices}[o]
\wrongchoice{2.5}
\correctchoice{5}
\wrongchoice{NaN}
\end{choices}
\end{question}

You can also record some one-line verbatims with the fancyvrb package (define your verbatim outside, before \onecopy):
\SaveVerb{theRcode}'sum(sapply(1:2^2,function(x) { x/2 }))'
...
\begin{question}{program}
What is the return value of the following R code?
\begin{center}
\UseVerb{theRcode}
\end{center}
\begin{choices}[o]
\wrongchoice{2.5}
\correctchoice{5}
\wrongchoice{NaN}
\end{choices}
\end{question}
For larger verbatims, the verbatimbox package can help you (define your verbatim outside, before \onecopy):
\begin{myverbbox}{\Rcode}
sum(sapply(1:2^2,function(x) { x/2 }))
\end{myverbbox}
...
\begin{question}{program}
What is the return value of the following R code?
\begin{center}
\Rcode
\end{center}
\begin{choices}[o]
\wrongchoice{2.5}
\correctchoice{5}
\wrongchoice{NaN}
\end{choices}
\end{question}
Reading the verbatim from a separate file often helps. As an
example, for a syntax highlighted python code stored in a file named
prog.py in the project directory, you can use
