更改考试类别中多列选项的“topsep”

Question

我试图让我的问题选择如下：

1. Question ....
   (A) choice ....                                 (B) choice ....
   (C) choice ....                                 (D) choice ....
   (E) choice ....

但是，如果我使用这个答案，问题和选项（A）之间的空间与环境中的默认值\question和默认值不同。\choicequestions类似问题，但 documentclass 不同。另外，我希望按 (A)(B)(C)(D)(E) 顺序排列选项（如上所示），而不是 (A)(D)(B)(E)(C)（下面的示例问题 1）。

这是我的 MWE

Answer 1

这显示了一个\makebox版本。它使用小页面而不是列表。因此，它不会分页。它也不会处理正确的选择或打印答案选项（工作量太大）。
