我需要四份不同的试卷，其中上述问题的顺序只是发生了变化，我需要在单独的纸张上给出相应试卷的答案。所以请帮我准备这些试卷。我需要通过打乱问题顺序来准备另一份试卷，我需要分别给出答案。我该怎么做？

还有一个问题 ＃＃
如果我想打乱问题顺序来准备四份不同的试卷，这些试卷有相同的问题，但问题编号不同，我该怎么做……？？
也就是说，我需要将上面给出的试卷标记为代码 A。并且我需要打印另一份标记为代码 B 的试卷，并且在此试卷中，第一个问题代码 A 应该在问题编号 5 中，同样其他问题也应该有不同的位置...
提前谢谢你的帮助...

我合并了这个答案解决你的问题。写完四个选项后，将正确的选项（a、b、c 等）放在括号中作为第五个选项。
