在 xsim 中随机播放问题

Question

正如标题所述，我想在使用xsim和tasks包时对问题进行打乱。这是我从具有正确选择环境的多项选择题由@cgnieder 编写。

\documentclass[12pt,a4paper]{article}
\usepackage[inline]{enumitem}
\usepackage[no-files]{xsim}
\usepackage{tasks}[newest]

\DeclareExerciseEnvironmentTemplate{item}
  {\item[\textbf{\GetExerciseName~\GetExerciseProperty{counter}}]}
  {}

\DeclareExerciseProperty{answer}

\newcommand*\answer[1]{%
  \XSIMexpandcode{%
    \SetExerciseProperty{answer}
      { \noexpand{\Alph{task}}}}%
  #1%
}

\newcommand*\getanswers{%
  \def\betweenanswers{\def\betweenanswers{\hspace{2em}}}%
  \ForEachUsedExerciseByID{%
    \betweenanswers##3\ExercisePropertyGet{##1}{##2}{answer}%
  }%
}

\xsimsetup{
  exercise/template = item,
  exercise/name = Q.,
  exercise/the-counter = \arabic{exercise}.
}

\NewTasksEnvironment[
  label = \textbf{\Alph*.},
]{choice}[\choice]

\newenvironment{questions}
   {\enumerate}
   {\endenumerate}

另外，是否可以在本地进行 shuffle？更具体地说，假设我有 10 个问题，并将它们分成 2 部分，一部分包含问题 1 到 5，另一部分包含其余问题。我想分别对每个部分进行 shuffle，并按顺序获取问题，例如，2 3 1 4 5 和 8 6 10 9 7。

Answer 1

这里有一种方法，首先将练习添加到集合中，然后随机输出它们，同时对它们进行打乱。使用多个集合，这还可以分别对练习块进行打乱。

\documentclass[12pt,a4paper]{article}
\usepackage{xsim}
\usepackage{tasks}

\NewTasksEnvironment[
  label = \textbf{\Alph*.} ,
  label-width = 15pt

\DeclareExerciseEnvironmentTemplate{item}
  {\description\item[\GetExerciseName~\GetExerciseProperty{counter}]}
  {\enddescription}

\DeclareExerciseEnvironmentTemplate{space}
  {\textbf{\GetExerciseProperty{counter}} }
  {\quad}
  
\newcommand*\answer[1]{%
  \XSIMexpandcode{%
    \SetExerciseProperty{solution-body}
      {\noexpand{\Alph{task}}}}%
  #1%
}

\DeclareExerciseCollection{part-A}

\xsimsetup{
  exercise/template = item ,
  solution/template = space ,
  exercise/name = Q. ,
  exercise/the-counter = \arabic{exercise}. ,
  exercise/collect ,
  random/sort = false
