我正在使用创建多项选择题考試班但是我遇到了两个问题：1)。想要有两列选项，但默认显示为 A、C、B、D，2)。选项中的数字是底部对齐而不是顶部对齐。有什么建议吗？以下是我的 MWE：
\documentclass{exam} \usepackage{multicol} \usepackage{graphicx} \begin{document} \begin{questions} \question \begin{minipage}[t]{0.65\linewidth} Consider the network graph shown in the figure, which of the following is NOT a \textit{tree} of this graph? \begin{multicols}{2} \begin{choices} \choice \includegraphics[scale=0.2]{example-image-a} \choice \includegraphics[scale=0.2]{example-image-b} \choice \includegraphics[scale=0.2]{example-image-c} \CorrectChoice \includegraphics[scale=0.2]{example-image-a} \end{choices} \end{multicols} \end{minipage} \hspace{2em}% \begin{minipage}[t]{0.35\linewidth} \vspace{-\baselineskip} \includegraphics[scale=0.4]{example-image-a} \end{minipage} \end{questions} \end{document}
运行上述代码后的输出如下：
然而，我希望有这样的东西：
答案1
这是一个选项：
\documentclass{exam}
\usepackage{multicol}
\usepackage{graphicx}
\usepackage{adjustbox}
\begin{document}
\begin{questions}
\question
\begin{minipage}[t]{0.65\linewidth}
Consider the network graph shown in the figure, which of the following is NOT a \textit{tree} of this graph?
\begin{choices}
\begin{multicols}{2}
\choice
\adjustbox{valign=t}{\includegraphics[scale=0.2]{example-image-a}}
\choice
\adjustbox{valign=t}{\includegraphics[scale=0.2]{example-image-b}}
\end{multicols}\par
\begin{multicols}{2}
\choice
\adjustbox{valign=t}{\includegraphics[scale=0.2]{example-image-c}}
\CorrectChoice
\adjustbox{valign=t}{\includegraphics[scale=0.2]{example-image-a}}
\end{multicols}
\end{choices}
\end{minipage}\hfill%
\begin{adjustbox}{minipage={0.30\linewidth},valign=t}
\includegraphics[width=\linewidth]{example-image-a}
\end{adjustbox}
\end{questions}
\end{document}
我用的是adjustbox包以获得所需的顶部对齐。对于编号模式，我使用了两个multicols环境，而不是一个。
我还改变了宽度\hbox 的scale选项。\includegraphicsand changed some spaces to prevent overfull
答案2
egreg 几乎可以解答所有问题。对于您的第一个问题，您可以使用 egereg 提供的解决方案：
%%------------------egreg's code starts-------------
\usepackage{environ,xparse}
\ExplSyntaxOn
\cs_undefine:N \choices
\cs_undefine:N \endchoices
\NewEnviron{choices}{%

有一次，我在做一些试卷时遇到类似的问题，他帮助过我。
对于第二个问题，您可以加载adjustbox包（就像 Gonzalo 所做的那样），但要使用export选项。这将使诸如valignetc 之类的键可用于\includegraphics命令。因此您必须使用
\includegraphics[scale=0.2,valign=t]{example-image-a}
请记住，在这种情况下graphicx是由 加载的adjustbox。
完整代码如下：
