如何自定义练习样式以使用自动编号书中的问题答案

Question

我是 LaTeX 新手，正在尝试为一本书编写几个问题和答案。我会在某个部分之后或根据文档中的任意位置选择使用问题答案。

因此，我希望问题和答案能够自动编号。一旦我在文档的其他部分使用另一组练习，编号就会重置。我的示例设计如图所示

MWE 可能如下

%文本的颜色和字体大小应可自定义，字体颜色可选为红色% %每个问题的问题和答案都分组在一起，并且有各种类型的问题%

%请注意，我已经有用于标记和引用的 tcolourbox，因此不需要标题练习 1.1 等。我只列出这个问题和答案，以便我能够根据需要使用它们。无需链接到任何部分或章节 % 因为我已经有了 colorbox 代码，我会将他的代码放在里面。%%

Answer 1

由于您明确要求xsim解决方案在评论中：

有人可以指导我使用 xsim 包吗？

下面是一个简单示例，展示了 MWE 的基本设置：

\documentclass{article}
\usepackage{xsim}
\usepackage{tasks}

\DeclareExerciseProperty{mc}
\newcommand*\correct[1]{%
  \XSIMexpandcode{\SetExerciseProperty{mc}{(\alph{task}) \unexpanded{#1}}}%
  #1%
}
\newcommand*\mcanswer{\GetExerciseProperty{mc}}

\settasks{label=(\alph*),label-width=14pt}

\xsimsetup{
  % uncomment if you want the answer directly after the questions:
  % solution/print = true ,
  exercise/name = Question ,
  solution/name = Answer ,
  exercise/template = runin ,
  solution/template = runin ,
  print-solutions/headings-template = custom
}
\renewcommand*\theexercise{\arabic{exercise}.}
\loadxsimstyle{layouts}

\DeclareExerciseHeadingTemplate{custom}{\section*{Answers}}


\begin{document}

\begin{exercise}
  Which if the following is a secondary memory Devices?
  \begin{tasks}(4)
     \task keyboard \task Monitor \task \correct{Hard Disk} \task SMPS
  \end{tasks}
\end{exercise}
\begin{solution}
  \mcanswer.
\end{solution}

\begin{exercise}
  Recently deleted files are stored in
  \begin{tasks}(4)
    \task \correct{Recycle bin} \task Taskbar \task My computer \task desktop
  \end{tasks}
\end{exercise}
\begin{solution}
  \mcanswer.
\end{solution}

\begin{exercise}
  What is RAM?
\end{exercise}
\begin{solution}
  RAM is Random Acess Memory.
\end{solution}

\begin{exercise}
  What is ROM?
\end{exercise}
\begin{solution}
  ROM is Read Only Memory.
\end{solution}

% uncomment if you want to print a list of all solutions:
% \printsolutions

\end{document}
