編譯後自動搖晃使用 LaTeX 建立的測試的問題和答案

我們假設我們有 30 個問題來為學生解決課文，而不是像 MWE 那樣的 2 個問題：

\documentclass[leqno,11pt,landscape,a3paper]{extarticle}
\usepackage{multicol,mathtools}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\begin{document}

\begin{multicols}{1}
\begin{enumerate}
\item La velocità di 1,00$\cdot 10^2$ m/s espressa in km/h è:

$\fbox{A}$  36 km/h.\\
$\fbox{B}$    360 km/h.\\
$\fbox{C}$  27,8 km/h.\\
$\fbox{D}$    $3,\!60\cdot 10^{8}$ km/h.\\
$\fbox{E}$ \begin{tabular}{lllllllllllll}
\multicolumn{1}{c}{} & \multicolumn{1}{c}{} & \multicolumn{1}{c}{} & \multicolumn{1}{c}{} & \multicolumn{1}{c}{} & \multicolumn{1}{c}{} & \multicolumn{1}{c}{} & \multicolumn{6}{c}{} \\
\hline
\end{tabular}

\item In fisica nucleare si usa l'angstrom (simbolo: 1\AA=$10^{-10}$ m) e il fermi o femtometro (1 fm= $10^{-15}$ m). Qual è la relazione tra queste due unità di misura?

$\fbox{A}$  1 \AA = $10^5$ fm.\\
$\fbox{B}$    1 \AA = $10^{-5}$ fm.\\
$\fbox{C}$    1 \AA = $10^{-15}$ fm.\\
$\fbox{D}$    1 \AA = $10^{3}$ fm.\\
$\fbox{E}$ \begin{tabular}{lllllllllllll}
\multicolumn{1}{c}{} & \multicolumn{1}{c}{} & \multicolumn{1}{c}{} & \multicolumn{1}{c}{} & \multicolumn{1}{c}{} & \multicolumn{1}{c}{} & \multicolumn{1}{c}{} & \multicolumn{6}{c}{} \\
\hline
\end{tabular}
\end{enumerate}
\end{multicols}
\end{document}

在編譯之後，是否有可能透過一些技術手段自動交換問題和答案的順序？

答案1

我在這裡提出一個可能的方法：

  • 首先，我定義一個帶有 6 個參數的巨集\definequestion：第一個是一些用來識別問題的「標籤」；第二個是問題正文；第三到第六個是可能的答案。問題以固定寬度t對齊，可以根據頁面和字體大小進行調整。\parbox\questionwidth
  • 巨集\usequestion{label}列印對應的問題。
  • 該巨集\printrandomquestions使用randomlist包以偽隨機順序列印問題。可選參數是種子，強制參數必須是逗號分隔的問題標籤清單。

重新整理答案的版本，請參閱下文。
