(A) claims suggest that the economy might not be as weak as some analysts previously thought
(B) claims suggests that the economy might not be so weak as some analysts have previously thought
(C) claims suggest that the economy might not be as weak as have been previously thought by some analysts
(D) claims, suggesting about the economy that it might not be so weak as previously thought by some analysts
(E) claims, suggesting the economy might not be as weak as previously thought to be by some analysts
下面这句话是 第16题的正确句子，（）部分是省略的内容
A surge in new home sales and a drop in weekly unemployment claims suggest that the economy might not be as weak as (the economy that was) some analysts previously thought.
我的问题是：
OG对C选项的解释是The sentence offers no plural subject to fit the passive verbhave been thought.
但是 对于C选项，我改成这个样子（加了【】里的内容，把have变成了has），这句话对吗？没有与C选项的解释矛盾吗？
A surge in new home sales and a drop in weekly unemployment claims suggest that the economy might not be as weak as【the economy that】has been previously thought by some analysts.
