Until Berta and Ernst Scharrer established the concept of neurosecretion in 1928, scientists believed that either cells secreted hormones, which made them endocrine cells and thus part of the endocrine system, or conducted electrical impulses, in which case they were nerve cells and thus part of the nervous system.

a) either cells secreted hormones, which made them

b) either cells secreted hormones, making them

c) either cells secreted hormones and were

d) cells either secreted hormones, in which case they were

e) cells either secreted hormones, which made them


Although I know when to use the construction of "either...or", however, this particular sentence confused me. Can anybody show me how to tackle this? thanks

A B C are wrong clearly for breaking || ism either and or should follow same noun/verb . In A B C either is followed by noun "cell" and or is followed by verb "conducted"

Between D and E , both are good in || ism as either is followed by secreted and or is followed by conducted.
E is correct here . D is unnecessarily wordy.

the OA is D. Here is why, take a look at option D:

d) cells either secreted hormones, in which case they were

the part that i've highlighted in bold is also parallel with the second part of the original sentence. i know, you missed that ;) that is why it is important to completely read the whole sentence of the original text in order to be more accurate with your selection. something that i constantly mess up with as well, but i'm learning.

what this question tries to do is testing whether you've read the whole sentence. if you haven't read the whole sentence, then you're likely to choose option e because it seems more concise. however, the original sentence indicates that it's important to choose option d to keep the whole structure parallel, even though it may sound more wordy than option e. so guys, read the whole sentence COMPLETELY, a big lesson that should be learnt from this question.

cells either secreted hormones... or conducted electical impulses
It should be between D and E

in which case they were endocrine cells ... || in which case they were nerve cells
D is correct.

E .. not parallel.

In E, the connector "which" refers to hormones and not the whole clause preceding it.

D for me.

E is not parallel and also "which" incorrectly refers to "secreted hormones"

Until Berta and Emst Scharrer ........, scientists believed that cells either secreted hormones, in which case they were endocrine cells and thus part of the endocrine system, or conducted electrical impulses, in which case they were nerve cells and thus part of the nervous system - parallel. Hence D

i agree with D as well,

but everyone is saying that "in which" modifies the clause the precedes it... I'm not so sure about that.

"in which" (just like "which") is a relative pronoun that modifies the noun that precedes it. or should i think of "in which case" a prepositional phrase?

Before I read the answer I had figured out that D was the correct one due to the required parallel. Nice example of the necessity to read the whole sentence, and thanks to Financier for moving the thread back up.

Clearly D,

A, B, C are not parallel so they out.

btw D and E, I was confused what to select, decided to read the sentence till the end, after this I chose D.

IMO D
cells must come before either...or and E is eliminated because which is placed next to hormones incorrectly

D for parallelism.

The un-underlined part gives the clues for D vs E.
