# Customize \ answerline in Exam class

I would like to create a quiz item that resembles this example:

____ 1. (p. 63) In a grouped frequency distribution, the mode falls in the most
frequently occurring class interval, more specifically, at its

-  a. upper nominal limit
-  b. lower nominal limit
-  c. upper real limit
-  d. midpoint.


When using the Exam class, I am unable to insert an \answerline next to the question number. An example of my code follows:

\documentclass[12pt,answers]{exam}
\begin{document}
\begin{questions}
\question (p. 63) In a grouped frequency distribution, the mode falls in the most
frequently occurring class interval, more specifically, at its
\begin{choices}
\choice upper nominal limit
\choice lower nominal limit
\choice upper real limit
\choice midpoint
\end{choices}
\end{questions}
\end{document}

-

You can customize the \questionlabel to get the same affect:
\renewcommand\questionlabel{\rule{0.25in}{0.5pt}\thequestion. }
