Como criar um ambiente de lista multicolunas com o pacote ‘enumerate’?

Question

Vamos considerar o seguinte exemplo

\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}

Isto produz:

Mas eu gostaria de produzir o seguinte usando o mesmo pacote:

OU

Como eu posso fazer isso?

Answer 1

Você pode usar omulticolpacote:

\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}

Aqui está outra opção, usando desta vez oenumitempacote e sua inlineopção:

\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

Esta parece ser uma tarefa ideal paratasks(aqui em combinação comexsheetsque a partir de maio de 2017 foi substituído porxsim):

\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}
