如何在文件末尾顯示多選答案鍵？

Question

我想在（多項選擇）考試頁面的末尾顯示答案鍵。我有一堆問題和答案（總是認為銀行中的第一個答案是正確的選擇），以及一些用於打亂問題及其答案的宏。所有文件均已附上（這裡）。輸出也如下圖所示。問題是我無法在頁面末尾顯示正確答案。

有各種軟體包可以幫助您建立考試和測驗。我對它們不太熟悉，因為我已經建立了自己的。這是我使用的一個非常簡化的版本：

\documentclass{article}

\makeatletter

\newcounter{ae@prob@cnt}
\let\ae@answer@key\relax

\newcommand\problem[1][a]{%%
  \stepcounter{ae@prob@cnt}%%
  \edef\ae@tmp{\theae@prob@cnt/#1}%%
  \ifx\relax\ae@answer@key
    \edef\ae@answer@key{\ae@tmp}%%
  \else
    \edef\ae@answer@key{\ae@answer@key,\ae@tmp}%%
  \fi
  Problem \theae@prob@cnt\hspace{1em}%%%
  }

\newcommand\presentanswerkey{%%
  \expandafter\ae@present@answers\ae@answer@key,\relax\@nil}

\def\ae@present@answers#1,#2\@nil{%%
  \def\ae@continue{}%%
  \ae@parse@pair#1\@nil
  \ifx\relax#2
  \else
    \def\ae@continue{\ae@present@answers#2\@nil}%%
  \fi
  \ae@continue}

\def\ae@parse@pair#1/#2\@nil{%%
  #1\hspace{0.25cm}#2\par}

\makeatother

\begin{document}

\problem[a] This is a question

\problem[b] This is another question

\problem[d] This is the penultimate question

\problem[c] My favorite question.

\presentanswerkey

\end{document}

更新

這是上面的修改版本：

\makeatletter
\let\ae@answer@key\relax
\newcommand\buildanswerkey[2]{%%
  \typeout{===>#1:#2}%%
  \edef\ae@tmp{#1/#2}%%
  \ifx\relax\ae@answer@key
    \xdef\ae@answer@key{\ae@tmp}%%
  \else
    \xdef\ae@answer@key{\ae@answer@key,\ae@tmp}%%
  \fi}

\newcommand\presentanswerkey{%%
  \typeout{===>\detokenize\expandafter{\ae@answer@key}}%%
  \expandafter\ae@present@answers\ae@answer@key,\relax\@nil}

\def\ae@present@answers#1,#2\@nil{%%
  \def\ae@continue{}%%
  \ae@parse@pair#1\@nil
  \ifx\relax#2
  \else
    \def\ae@continue{\ae@present@answers#2\@nil}%%
  \fi
  \ae@continue}

\def\ae@parse@pair#1/#2\@nil{%%
  #1\hspace{0.25cm}#2\par}

\makeatother

將其儲存在名為 的檔案中buildanswerkey.tex並將其載入到您的commandsPerm.tex檔案中。

在 中commandsPerm.tex，我重寫了幾行如下：

%%-----------------------------------------
\pgfmathrandomitemwithoutreplacement\j{tmp}
\sbox\answera{\ifx\j\correctAnswer * \expandafter\buildanswerkey\expandafter{\thequestion}{a}\fi\ifcase\j\relax\or#1\or#2\or#3\or#4\fi}%
\ifx\j\javab \questionhaspoints{\thequestion = 1} \fi
%%-----------------------------------------
\pgfmathrandomitemwithoutreplacement\j{tmp}
\sbox\answerb{\ifx\j\correctAnswer * \expandafter\buildanswerkey\expandafter{\thequestion}{b}\fi\ifcase\j\relax\or#1\or#2\or#3\or#4\fi}%
\ifx\j\javab \questionhaspoints{\thequestion = 2} \fi
%%-----------------------------------------
\pgfmathrandomitemwithoutreplacement\j{tmp}
\sbox\answerc{\ifx\j\correctAnswer * \expandafter\buildanswerkey\expandafter{\thequestion}{c}\fi\ifcase\j\relax\or#1\or#2\or#3\or#4\fi}%
\ifx\j\javab \questionhaspoints{\thequestion = 3} \fi
%%-----------------------------------------
\pgfmathrandomitemwithoutreplacement\j{tmp}
\sbox\answerd{\ifx\j\correctAnswer * \expandafter\buildanswerkey\expandafter{\thequestion}{d}\fi\ifcase\j\relax\or#1\or#2\or#3\or#4\fi}%
\ifx\j\javab \questionhaspoints{\thequestion = 4} \fi

然後當你編譯文件時，你會得到一個答案。我沒有費心弄清楚您打算如何創建答案密鑰，但透過在\presentanswerkey退出mcquestions環境之前調用，您將獲得正確的密鑰：
