在exsheets中随机选择子问题

在 MWE 中：

\documentclass{article}
\usepackage{exsheets}
\SetupExSheets{counter-format=}
\begin{document}
\begin{question}[name=Answer the following in one sentence]
  \begin{enumerate}
    \item Who is the President?
    \item Who is the Prime minister?
    \item \includequestions[random=2]{classA}
  \end{enumerate}
\end{question}
\end{document}

classA.tex 的内容为：

\begin{input}
  \begin{question}
    Who is the Defence Minister?
  \end{question}
  \begin{question}
    Who is the Home Minister?
  \end{question}
  \begin{question}
    Who is the Finance Minister?
  \end{question}
  \begin{question}
    Who is the External Affairs Minister?
  \end{question}
\end{input}

编译后的样子如下：

问题围绕第3条展开，题意重复，计数器不前进。

我该如何克服这个问题？那么，它会随机选择问题并将问题编号 3 和 4 分配给它们吗？

如果 exsheets 不能做到这一点，还有其他包可以做到这一点吗？

答案1

我认为不能得到令人满意的解决方案，exsheets但它的后继者可以xsim– 诀窍是定义另一种仅用于子问题的练习类型。

\documentclass{article}
\usepackage{xsim}

\DeclareExerciseType{subquestion}{
  exercise-env = question ,
  solution-env = answer ,
  exercise-name = Question ,
  solution-name = Answer ,
  exercise-template = item ,
  solution-template = item
}

\DeclareExerciseProperty{title}

\DeclareExerciseEnvironmentTemplate{named}
  {\subsection*{\GetExercisePropertyTF{title}{#1}{??}}}
  {}

\DeclareExerciseEnvironmentTemplate{item}
  {\item}
  {}

\xsimsetup{
  exercise/template = named
}

\DeclareExerciseCollection{exercise-pool}

\begin{filecontents*}{\jobname-exercises.tex}
\begin{question}
  Who is the Defence Minister?
\end{question}
\begin{question}
  Who is the Home Minister?
\end{question}
\begin{question}
  Who is the Finance Minister?
\end{question}
\begin{question}
  Who is the External Affairs Minister?
\end{question}
\end{filecontents*}

\begin{document}

\collectexercises{exercise-pool}
\input{\jobname-exercises.tex}
\collectexercisesstop{exercise-pool}

\begin{exercise}[title=Answer the following in one sentence:]
  \begin{enumerate}
    \item Who is the President?
    \item Who is the Prime Minister?
    \printrandomexercises[collection=exercise-pool]{2}
  \end{enumerate}
\end{exercise}

\end{document}

PS：代码需要xsimv0.10，在撰写本文时（2017-09-18 14:57 CEST）尚不可用，但正在向 CTAN（和流行的发行版）迈进。
