OG 12—138，谁和谁对比，应该怎么看？？

听sophie

138. 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
(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

A  Th is sentence implies a comparison between the comet and its return.
B  Th is sentence implies a comparison between the comet and its return; had is the wrong auxiliary verb form because it must be followed by caused instead of cause.
D  Th is sentence implies a comparison between the comet and its return.

上面是OG中给的解释，
不明白的是ABD中都说了句子比较的是comet和return，应该怎么去看比较的对象是谁，在解决这个对比的问题时应该如何来看一句话呢，怎么去拆分句子结构？？

听现在这里谢过各位啦！！

E有歧义
歧义1：没有任何一次HC的观测比其1910-1911的观测产生如此的轰动。（in other historical sighting vs. in its return of 1910-1911)
歧义2：历史上HC的观测从来没有像其1910-1911的观测产生如此轰动。(HC cause vs. its return cause)
若想消除歧义
若真正含义是1，则需要补出介词
若真正含义是2，则需要补出助动词
AD 补出did? caused 不符合逻辑，从语法和逻辑上看AD都是一样的，因为不能同对，所以AD同错。
B 补出had ? had cause 时态错且不符合逻

Rephrase with C -In no other historical sighting did Halley's comet cause such a worldwide sensation as (it did) in its return of 1910-1911 (We can omit 'he did' and still convey the same meaning)
as introduces a comparison "in no other sighting" can be logically compared to" in its return“
--->>
Halley’s Comet did  cause such a worldwide sensation in no other historical sighting as (it did )in its return of 1910–1911.
ABD拿A举例
A： In no other historical sighting did Halley’s Comet cause such a worldwide sensation as did its return in 1910–1911.
Halley’s Comet didddd cause such a worldwide sensation in no other historical sighting as didddd its return in 1910–1911.(前后的verb对应）
我觉得这里准确的说是："the sensation caused by the HComet”  VS “its return" 逻辑就很有问题了,一个是由HC引发的轰动，一个是sighting.
BD跟A原理是差不多的.
而OG上说comet跟its return比较，主要是根据结构上~ In no other historical sighting did (Halley’s Comet) cause such a worldwide sensation as did( its return) in 1910–1911
