A Numerical Response problem has seven major parts by default:

\begin{enumerate}
\item The \textbf{Script} is the heart of advanced Numerical Response
problems. It can be used to decide some of the parameters of the problem,
compute the answer to the problem, and do just about anything else you can
imagine. The Script language is \textbf{Perl}. You do not need to know Perl
to use the \textbf{Script} block because  we will be stepping through some advanced
examples in this chapter, but knowing Perl can help.
\item Like other problem types, the \textbf{Text Block} is used to display the
problem the student will see. In addition, you can place variables in the
\textbf{Text Block} based on computations done in the \textbf{Script}.
\item The \textbf{Answer} is the answer the system is looking for. The answer can 
use variables calculated/defined in the problem's \textbf{Script} block, allowing the answer to be
determined dynamically (including randomization).
