OG12--31 OG的解释没看明白~~

烟囱XXQ

Unlike the conviction held by many of her colleagues that genes were relatively simple and static, Barbara McClintock adhered to her own more complicated ideas about how genes might operate, and in 1983, at the age of 81, was awarded a Nobel Prize for her discovery that the genes in corn are capable of moving from one chromosomal site to another.

(A) Unlike the conviction held by many of her colleagues that genes were
(B) Although many of her colleagues were of the conviction of genes being
(C) Contrary to many of her colleagues being convinced that genes were
(D) Even though many of her colleagues were convinced that genes were
(E) Even with many of her colleagues convinced of genes being

答案是D,其他的都明白，就是OG给出的解释这句有点没看懂，求详细解析！！！

The clearest and most efficient way to make the
comparison is to introduce McClintock’s
colleagues’ convictions in a dependent clause,
followed by a main clause that introduces
McClintock’s diff erent way of doing things and
goes on to explain how successful she was.

为什么非得是dependent clause，...by a main clause才clearest and most efficient way呢？

这不是一种语法问题，是一种写作的手法，写作技巧。告诉这样写最好。这有什么问的

所以你就知道GMAT喜欢什么样的表达方式啊，它就是不喜欢题干里 介词+名词+分词短语修饰+隔开几个词指代的宾语从句 的复杂模糊的书写方法。

我觉得是这样的，因为比较的是一个观点和MC坚持的观点，而未画线部分的句子是以MC这个人开头的，所以用短语就没办法直接与观点比较，只能直接与MC这个人比较。
因此要用从句~~
