As it is with traditional pharmacies, on-line drugstores rely on prescriptions to be successful, since it is primarily prescriptions that attract the customers, who then also buy other health-related items.

A.As it is with traditional pharmacies, on-line drugstores rely on prescriptions to be successful
C. As is the case with traditional pharmacies, prescriptions are the cornerstone of a successful on-line drugstore
答案是C
我想问下C的as+从句是不是个全倒装？如果是的话，as引导方式状从不是不可以倒装吗?

另外关于as的句子：She is tall, as is her mother. 这里的as 是充当什么？后半句是从句吗？对这个有点模糊，望指教。。。

还有道OG题：
In no other historical sighting did Halley's Comet cause such a worldwide sensation as did its return in 1910-1911.
A did its return in 1910-1911
C in its return of 1910-1911
D its return of 1910-1911 did
E its return in 1910-1911 key：C
不太明白这题as 后面是和谁进行比较。。。

第一道题，我可能解释不清楚。在练习过程中，我们会经常遇到这样的问题，似乎GMAT很偏爱这个结构as be the case with，它大多数情况下是正确答案。至于为什么，期待NN解答。
第二道题，语序变化了，改成正常语序，你就能看明白了 Halley's Comet caused such a worldwide sensation in no other historical sighting as in its return in 1910-1911。是in no other historical sighting和in its return in 1910-1911比较。
