Neurosecretion

by HarvardDreamin » Wed Sep 10, 2008 1:22 pm
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

What is your answer and why?

Many thanks in advance

IMHO d) cells either secreted hormones, in which case they were is the correct answer.

starting with "either cells" is incorrect because it is not the number of cells we are comparing. Cells should be the subject here: Cells either did X in which case they were A or did Y in which case they were B.

Please post the OA.

Thanks.

it is D because "cells" has to come before "either"

Question to Ron

Can you please elaborate on the usage of "in which case" .

As per my knowledge, "in which" is used as a noun modifier . What do you make of "in which case" ? It is certainly not a noun modifier .

Your comments please

This question tests the idiom either X or Y where X and Y must be parallel.Hence A,B,C can be eliminated easily.In E, which refers to the closest noun hormones, but the logic of the sentence is such that the word following hormones should express the secretion of hormones.Hence E is incorrect.Correct answer is D.

what's the source of this problem? is it official?

i'm going to withhold judgment on this construction until i know the source of the question. (original source, please - other forums don't count as sources. thanks)

in this case, then, the correct answer explains itself: "in which case" is apparently allowed to refer to the whole idea of the preceding clause, rather than just the preceding noun.

note that THIS particular problem is easily resolved using elementary parallelism.
the second (non-underlined) portion says "...or Y, in which case"
so you should pick "either X, in which case". perfect parallelism.

on the other hand, it's good to get this takeaway about "in which case", so that you'll be able to solve problems that DON'T feature such perfect parallelism (or don't feature parallelism at all).

Ron,

Does E have the problem of double object? "cells either secreted hormones, which made them "

that's problematic, yes. because "hormones" and "them" are both direct objects, "them" seems to point (mistakenly) to "hormones".
