并输出

如果答案选项很长，则上面有空格。如果答案选项很短，则上面没有空格。长答案选项的开头是短答案的开头。如何解决这个问题？

Answer 1

只需在命令的tcolorbox中添加选项键即可\kutu：

• oversize：防止 tcb 的大小与文本长度成比例，
• halign=center：使 tcb 的文本水平居中。

\newcommand{\kutu}[2]{%
    \begin{tcolorbox}[%
        oversize,
        halign=center,
        enhanced jigsaw,
        breakable, left=0mm,
        right=0mm,bottom=0mm,top=0mm,
        colback=red!5!white,
        colframe=red!75!black,
        pad at break=1mm]
        #1%
        \begin{flushright}
            \textit{#2}
        \end{flushright}
    \end{tcolorbox}
}

更新

如果希望文本和 tcolorbox 顶部边框之间留出尽可能小的空白，可以在环境\abovedisplayskip=0pt开始后立即添加声明\kutu。文本和边框之间的空格也已更改为：left = -1mm, right = -1mm。

\soru{%
    \item Question one?
    \dort{ITU}{ECC}{HAM}{ARRL}
}

\kutu{%
\abovedisplayskip=0pt
\denk{International Telecommunication Union}}{\A}
\kutu{%
\abovedisplayskip=0pt
\denk{International Union}}{\A}
