如何使用包“enumerate”创建多列列表环境？

Question

让我们考虑以下例子

\documentclass{article}
\usepackage{enumerate}
\begin{document}
\begin{enumerate}
 \item Which of the following numbers is the largest ?\\
$2^{3^4},2^{4^3},3^{2^4},3^{4^2},4^{2^3},4^{3^2}.$

\begin{enumerate}[(a)]
\item  $2^{3^4}$
\item  $3^{4^2}$
\item  $4^{3^2}$ 
\item $4^{2^3}$
\end{enumerate}

\end{enumerate}
\end{document}

得出的结果为：

但我想使用同一个包来生成以下内容：

或者

或者

我怎样才能做到这一点？

Answer 1

您可以使用multicol包裹：

\documentclass{article}
\usepackage{enumerate}
\usepackage{multicol}
\begin{document}
\begin{enumerate}
 \item Which of the following numbers is the largest?\\
$2^{3^4}$, $2^{4^3}$, $3^{2^4}$, $3^{4^2}$, $4^{2^3}$, $4^{3^2}$.

\begin{enumerate}[(a)]
\begin{multicols}{2}
\item  $2^{3^4}$
\item  $3^{4^2}$
\item  $4^{3^2}$ 
\item $4^{2^3}$
\end{multicols}
\end{enumerate}

\end{enumerate}
\end{document}

这是另一个选择，利用这次enumitem包及其inline选项：

\documentclass{article}
\usepackage[inline]{enumitem}
\begin{document}
\begin{enumerate}
\item Which of the following numbers is the largest?\\
$2^{3^4}$, $2^{4^3}$, $3^{2^4}$, $3^{4^2}$, $4^{2^3}$, $4^{3^2}$.

\begin{enumerate*}[label=(\alph*),itemjoin={\hspace{\fill}}]
\item  $2^{3^4}$
\item  $3^{4^2}$
\item  $4^{3^2}$
\item $4^{2^3}$
\end{enumerate*}

\end{enumerate}
\end{document}

Answer 2

这看起来是tasks（此处结合exsheets自 2017 年 5 月起，该标准已被xsim)：

\documentclass{article}
\usepackage{exsheets}
% this sets up the question headings to be a simple run-in number:
\SetupExSheets{
  headings = runin-nr ,
  headings-format = \normalfont
}

\usepackage{tasks}
% this creates a new environment `choices' where the single
% choices are indicated with \choice and are labelled (a), (b), ...:
\NewTasks[counter-format=(tsk[a]),label-width=2em]{choices}[\choice]

\begin{document}
\begin{question}
  Which of the following numbers is the largest?\\
  $2^{3^4}$, $2^{4^3}$, $3^{2^4}$, $3^{4^2}$, $4^{2^3}$, $4^{3^2}$.
  \begin{choices}
    \choice $2^{3^4}$
    \choice $3^{4^2}$
    \choice $4^{3^2}$ 
    \choice $4^{2^3}$
  \end{choices}
\end{question}

\begin{question}
  Which of the following numbers is the largest?\\
  $2^{3^4}$, $2^{4^3}$, $3^{2^4}$, $3^{4^2}$, $4^{2^3}$, $4^{3^2}$.
  % the optional argument in parentheses determines the number of columns:
  \begin{choices}(2)
    \choice $2^{3^4}$
    \choice $3^{4^2}$
    \choice $4^{3^2}$ 
    \choice $4^{2^3}$
  \end{choices}
\end{question}

\begin{question}
  Which of the following numbers is the largest?\\
  $2^{3^4}$, $2^{4^3}$, $3^{2^4}$, $3^{4^2}$, $4^{2^3}$, $4^{3^2}$.
  \begin{choices}(4)
    \choice $2^{3^4}$
    \choice $3^{4^2}$
    \choice $4^{3^2}$ 
    \choice $4^{2^3}$
  \end{choices}
\end{question}

\end{document}
