考虑我之前的两个问题：

方格用于选择答案，与数学答案完美对齐

首先@egreg 的代码

\documentclass{article}

\newcommand{\squarecap}[1]{\fbox{\makebox[\height]{#1}}}

\begin{document}

\squarecap{A}\par
\squarecap{B}\par
\squarecap{C}\par
\squarecap{D}\par

我怎样才能将代码组合起来以获得完全平方数（不使用siunitx包）并得到我需要的标记十字作为校正器，我可以在我给学生的测试打印件中将其消除？

答案1

我相信下面的代码应该或多或少能满足您的要求。我假设每个问题始终只有一个正确答案（否则，我们可能不得不更改输入语法，因为自由格式的答案目前不是输入的一部分）。正确答案必须用前面的[x]或表示，[X]如下所示：

\question{La velocità di \SI{1,00e2}{m/s} espressa in \si{km/h} è:}{
     {\SI{36}{km/h}.}
  [X]{\SI{360}{km/h}.}
     {\SI{27,8}{km/h}.}
     {\SI{3,60e8}{km/h}.}
}

[x]或之前和之后的空格会被忽略[X]，因此这种输入也是合法的：

\question{La velocità di \SI{1,00e2}{m/s} espressa in \si{km/h} è:}{
      {\SI{36}{km/h}.}
  [X] {\SI{360}{km/h}.}
      {\SI{27,8}{km/h}.}
      {\SI{3,60e8}{km/h}.}
}

如果对于给定的问题，所有建议的答案都没有这样的标记，则自由形式的答案（在上面的输入中没有相应的行）被认为是正确的。

\ShowCorrectAnswers是否打印每个问题的正确答案旁边的复选标记取决于和的使用\HideCorrectAnswers（见下面的屏幕截图）。这些命令遵守 TeX 分组规则（即它们在本地起作用）。或者，您可以：

  • sebmcq使用show-correct-answers=true或show-correct-answers=false或加载包

  • 使用\sebmcqSetup{show-correct-answers=true}或\sebmcqSetup{show-correct-answers=false}。

该\sebmcqSetup命令尊重分组并接受以下选项。它们也可以在调用中\usepackage{sebmcq}以及在环境的可选参数中传递questionnaire。

  • questionnaire-env（最初：）enumerate。这是 用来打印所有问题的环境questionnaire。它必须接受\item与 中工作方式相同的命令enumerate。

  • shuffle-questions（初始值为false）；值可以是true或false。如果使用不带值的选项，则表示true。

  • shuffle-answers（最初：false）。该值的解释方式与 相同shuffle-questions。

  • show-correct-answers（最初：）false。价值也是如此。

  • after-answer-num-skip=〈skip〉确定每个答案数字/字母与相应答案之间的水平间距。

  • answer-number-format=〈code〉允许完全改变答案数字的格式（字母、Alph、罗马、罗马、阿拉伯；自定义 Ti钾Z 代码在其周围绘制一个圆形或矩形等）。#1〈code〉 参数中出现的任何 都将被建议的答案数字（一个整数）替换。

下面的示例展示了如何使用这些选项。
