关于抽象名词大于分词动名词

ＧＷＤ里的一道ＳＣ题

In 1713, Alexander Pope began his translation of the Iliad, a work that, taking him seven years until completion, and that literary critic Samuel Johnson, Pope’s contemporary, pronounced the greatest translation in any language.

1. his translation of the Iliad, a work that, taking him seven years until completion, and that literary critic Samuel Johnson, Pope’s contemporary, pronounced
2. his translation of the Iliad, a work that took him seven years to complete and that literary critic Samuel Johnson, Pope’s contemporary, pronounced
3. his translation of the Iliad, a work that had taken seven years to complete and that literary critic Samuel Johnson, Pope’s contemporary, pronounced it as
4. translating the Iliad, a work that took seven years until completion and that literary critic Samuel Johnson, Pope’s contemporary, pronounced it as
5. translating the Iliad, a work that had taken seven years to complete and literary critic Samuel Johnson, Pope’s contemporary, pronounced it

自己是按照to complete, 时态来做这到道题的，

but have no idea that whether translating the A or his tranlation of the A is better

According to XDF, seems that his translation is better,

哪位朋友来帮忙解释一下啊，

我觉得这道题pronunced的后面如果没有as那就一定错，而to complete一定比until completion对。所以就选c了。所谓绝对错误大于相对错误嘛，你说的那个名词优于动名词在这里只是一个相对错误吧。对吗？愿意听听大家的意见

答案是B的...

我觉得as　不能加哦，　多余的．．

翻译起来感觉是　'被认为是相当于'　的意思

昨天朋友做了这题，一看就排除了D, E觉得很诧异的
