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?

D for parallelism.

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

Until Berta and Emst 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

The SC has been discussed several times. But the pronoun references in each answer choice are not clear and never been discussed. Can we have some expert comments on the pronoun reference, please.

This has been discussed in another forum post, but before I address the pronoun issue, let me give a quick explanation.

Following rules of parallelism, cells either A or B, hence (D) or (E).

Next case of parallelism is 'in which case' - notice that the non-underlined part contains this phrase and to maintain parallelism the answer has to as well.

Now for the pronoun issue. 'They' is only ambiguous if it could reasonably refer to more than one plural subject. To say that scientists were nerve cells or endocrine cells is clearly absurd and thus not reasonable. Therefore, there is no ambiguity in the use of 'they.'

Hope that helps

I was confused between B and D.
B] ", making them..." could be verb+ing modifier, in which case later phrase has to modify the entire previous clause. Here is modifying only "cells". This makes is a bad choice
D] is good from point of view of parallelism
A and E have wrong use of "which"
C is changing the meaning of sentence.
Thus D prevails.

D is correct. Parallel. E is not parallel.
