我如何生成测试版本？

Question

我正在使用考试文档类，但我没有使用“开始问题而是使用枚举来生成问题，因为问题是图像”

我正在寻找一种生成版本的方法，目前我很苦恼。

\documentclass{exam}
\usepackage{graphicx} % Required for inserting images
\usepackage[Export]{adjustbox}



\pagestyle{headandfoot}
\runningheadrule
\firstpageheadrule
\firstpageheader{Physics AB: Dynamics Test}{\hspace{8cm}Name:\rule{2cm}{0.5pt}}{\textbf{VERSION A}}
\runningheader{Physics AB: Dynamics Test}
{}
{\textbf{VERSION A}}
\firstpagefooter{}{}{}
\runningfooter{}{}{}
