关于大全303的另一个问题(已解决)

For almost a hundred years after having its beginning in 1788, England exiled some 160,000 criminals to Australia.

(A) For almost a hundred years after having its beginning in 1788

(B) Beginning in 1788 for a period of a hundred years

(C) Beginning a period of almost a hundred years, in 1788

(D) During a hundred years, a period beginning in 1788

(E) Over a period of a hundred years beginning in 1788

正确答案是E

前人都讨论过这个问题，但是大都关于限制和非限制性定语从句的讨论。

我的问题是:

1.原文说的是almost a hundred years, 而E的意思确是确定的a hundred years,是不是对题目原意有修改？

毕竟almost不确实是正好100 years.

2. B错在哪里？

请帮忙解惑！

2，逻辑主语不对，不是England begin，是a period begin

1，可能需要体会over的意思。
