原文表示可能性的词可以改变吗?

none123

新东方的丽丽老师说代表着文章预期的确定程度的词不可以随意改变，但是就真的不可以改变吗？比如og12 的第五题
       Of all the vast tides of migration that have swept through history,maybe none is more concentrated asthe wave that brought 12 million immigrants onto American shores in little more than three decades.e

(A) maybe none is more concentrated as

(B) it may be that none is more concentrated as

(C) perhaps it is none that is more concentrated than

(D) maybe it is none that was more concentrated than

(E) perhaps none was more concentrated than
最后答案是e，没有问题。但最后还是把原文中的maybe改成了perhaps。是不是代表情态动词不可以作为评价一个选项正确与否的标准，还是说意思相近的，可能性程度差不多的是可以互相替换的？求大牛解释。

语法笔记里写过,perhaps 比maybe更加formal
而且这算三类错误我觉得
先把八大类错误揪出来再考虑这种小细节

弱弱的问一句。。八大错误是哪八大错误啊？在哪本书可以看到？

去看曼哈顿语法，论坛里有电子版的。八大类刚刚也有人发帖啦
