补充250题第99题，请指教

99.    
The use of chemical pesticides in this country is equally extensive or more so than ten years ago.
(A) equally extensive or more so than ten years ago
(B) equal to or more extensive than ten years ago
(C) as extensive as ten years ago or more
(D) equal to, if not more, than ten years ago
(E) as extensive as it was ten years ago, if not more so

答案E，我错选B
请帮我分析一下E的语法点和B的错误原因，谢谢：）

祈晴坊主

B罗嗦结构，而且并列表达错
因为要语法上对，只要要用 equal extensive to or more extensive than ~~~

记得OG中有解释，当表示至少怎么样时，不用在重复表示比什么多了

谢谢小晴MM，不过B项从语法上有没有缺少equal extensive to or more extensive than （it was） ten years ago

it was 是不是不能够省略：）

祝小晴MM越来越PP，赚好多好多的money，可以请我吃饭：）哈哈！

我觉得是这样的，如果是比较的状语ten years ago就不用补足it was了。

huangpen

equal 这个词表示两者是完全相同的，在比较适应慎用。

这里的意思明显是强调程度上的extensive, 而不是说各方面, B D 明显有歧义。

我觉得it was不能省 因为 前面是一般现在时 如果比较的两个部分的时态不一样 那么it was不能省略

lexie

还要强调一下it was这里绝对不能省

为什么it was 不可以省略？

The gyrfalcon, an Arctic bird of prey, has survived a close brush with extinction; its numbers are now five times greater than when the use of DDT was sharply restricted in the early 1970’s.
(A) extinction; its numbers are now five times greater than
(B) extinction; its numbers are now five times more than
(C) extinction, their numbers now fivefold what they were
(D) extinction, now with fivefold the numbers they had
(E) extinction, now with numbers five times greater than
the key:A。
省略掉its numbers were, 但前后时态不同，为什么可以省略？
