exam-minipage：在标题内使用 minipage

Question

跟进我之前的问题[1，2]相反，我尝试使用minipage环境，以便能够自由地断线并使用exam宏（例如\numquestions），而使用盒子时则无法做到这一点。

但是，还有一些问题需要解决：

1-对于第一行，我如何分别控制所有三个规则之间的顶部和底部间隔minipages以及顶部和底部规则？此外，为什么顶部间隔比底部间隔小得多？

2-在第二行，如何使 mdframed-box 紧密地放置在水平规则之间，而没有顶部和底部的空白？

3- 在第三行中，为什么小页面倾斜且放置不正确，尽管它们的总宽度加起来为\textwidth，并且位置选项设置为吨是吗？虽然当我稍微减小这两个小页面的宽度并尝试其他小页面时，它们又会垂直对齐，这对我来说没有意义。同样，我需要一种方法来控制相邻水平规则的顶部和底部分离。

Answer 1

我修改了代码，将 mdframed 框替换为 tcolorbox 框，最终使其可以工作。
