Could someone please share a working example of using the matching environment in a document class exam. I am new to using the exam document class and am unable to find a way to set up the matching style. I found exactly what I wanted in a document written in 2001, but cannot make it work in the new class. Here is what I have so far.
\documentclass[12pt]{exam}
% other information
\begin{document}
%exam header information
\begin{matching}[title={Match the following terms}]
\pair{Field 1}{answer for 1}
\pair{Field 2}{answer for 2}
\pair{Field 3}{answer for 3}
\end{matching}
\end{document}
Thanks.
