我的问题中需要这些命令并进行以下对齐..即输出应该是这样的。
1.Which subject you like very much?
(a) mathematics (b) physics
(c) chemistry (d) biology
我该怎么办呢？如果选择很长，它必须自动对齐...请帮帮我...
答案1
multicols包中的环境可能multicol适合您。您可以使用columnbreak在任意两个答案选项之间拆分列。如果答案的长度大致相同，则行可能会对齐，但如果答案的长度不同，则选项不会自动对齐。您可以使用选项\\[length]末尾的结构来增加空间，如第二个问题所示。但是，这不是自动的。

\choice Not if it is a hard subject that requires lots of concentration. Please do not make me have to read a very long answer.
\correctchoice Doesn't matter. I had the answers in advance. I don't have to read anything. So I do not really care how long the answer is.
