（1）     GWD-18-Q11

In no other historical sighting did Halley’s comet cause such a worldwide sensation as did its return in 1910-1911.

1. did its return in 1910-1911

2. had  its 1910-1911 return

3. in its return of 1910-1911
4. its return of 1910-1911 did

5. its return[ in 1910-1911

as前后要平行的部分是In historical sighting,所以选项必须有相同结构的.

只有C答案符合要求.

 我也是选的C呀。可是答案是A。 应该怎么解释呢？

1.GWD的答案错了.PREP的答案是C (请参照新PREP 1-245).

2.主语是哈雷彗星,不是哈雷彗星的回归,A答案不平行.

我試著還原句子，請各位看看有無錯誤

Halley’s comet in no other historical sighting cause such a worldwide sensation as in its return in 1910-1911.

這樣就比較容易看出比較的對象

In no other historical sighting did Halley’s comet cause such a worldwide sensation as did its return in 1910-1911.

 我也选Ｃ　　in its return of 1910-1911　与　In no other historical sighting　构成平等结构．选Ａ变成了ＣＯＭＥＴ　与　ＣＯＭＥＴ＇ＲＥＴＵＲＮ比较，逻辑意思不合理．
