求教GWD20-32
Q32:A surge in new home sales and a drop in weekly unemployment claims suggest that the economy might not be as weak as some analysts previously thought.

• claims suggest that the economy might not be as weak as some analysts previously thought
  
  
• claims suggests that the economy might not be so weak as some analysts have previously thought
• claims suggest that the economy might not be as weak as have been previously thought by some analysts
  
• claims, suggesting about the economy that it might not be so weak as previously thought by some analysts
• claims, suggesting the economy might not be as weak as previously thought to be by some analysts

作为答案的B选项中so...as的用法，这里不是否定句么？为什么A中用as...as(正确答案是A)

B的错误在suggest。。。had previouly estimated应该是可以的，见TN3-14
Even though more money was removed out of stock funds in July than in any other month since October 1987, sales of fund shares in July were not as low as what an industry trade group had previously estimated

查了下语法书。。as...as。。。可由于肯定或否定，但so....as，只用于否定，是我自己才疏学浅了。。。。希望不会误导大家

言之有理，两个名字并列，谓语动词是该用复数，have是作为从句谓语动词，可是还是不明白A，GMAC出题一向严谨，对于喜欢秒题的人确实是很大的挑战，还是希望能把as...as,和so...as的知识给弄懂，是不是否定不一定用so.....as，我就想明白这个，明白了，只要见到错误就可以直接排除 ，节约时间

B的主语也不是the economy而是some analysts,这里确实是so...as更好，但是我觉得应该不是correctness的错，所以不能优先考虑，而B中其他的错都是correctness的级别

B中have 是不该用，因为执行者是the economy,这个我懂，可是如果A对，我就有点不懂so ....as,与as..as ,的用法了，我正因为这个，一开始就排除了A。。。。。就是搞不懂什么时候as改为so，难道这里不应该？

我觉得lz的关注点错了，先看主要的错，B的主谓不一致A and B结构谓语用复数，另外previouly是过去式的标志，而B用了现在完成时
