GWD-2-11请大家指点迷津

in no other historical sighting did halley's comet such a worldwide sensation as did its return in 1910-1911.

a.

b.had its 1910-1911 return

c.in its return of 1910-1911

d.its return of 1910-1911 did

e.its return in 1910-1911

正确选项：a

不明白的地方有：

1.这个句子的句子结构，开头是一个介宾短语，之后一个did，构成倒装，对吗？如果对，这个句子怎么还原成正常语序？

2.a项中的did是什么状况，能理解句子意思，但是分析不清楚其语法构成，能否讲解一下这里的语法现象？跟前面的such n as..结构有关系吗？

拜谢！

我嘗試的還原句：

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

強調in no other historical sighting（否定語氣), 於是倒裝

In no other historical sighting did Halley's comet cause a worldwide sensation as....

as的後面基於parallelism, 也要倒裝 did its return......

有錯請指正！
