Concepts Tested – Verb Tense, Run-on, Pronoun Reference

The sentence is correct the way it is written.

B - The use of the past continuous tense (were not showing) is incorrect. We
actually need to use the past perfect tense to match ‘had begun’ in the non-
underlined part

C - This is a run-on sentence because a comma is used to connect two
independent clauses

D - By omitting the pronoun ‘they’ or ‘them’, this sentence fails to clarify who
should have shown the signs of the disease

E - The usage of the pronouns ‘it’ and ‘they’ introduces ambiguity in the sentence

Hi carcass,

could you please explain why in 3d question in answer choice A "they" is not ambiguous? Can't "they" refer to both rats and scientists?
Why in answer choice D by omitting "they" the sentence becomes unclear? Isn't it clear that "signs of disease shown" refers to rats? Here is the sentence without some fluff: The scientists noted that rats had begun to die even without signs of disease shown. Shown modifies signs. "Even without signs" is a phrase I guess that modifies die.

3) The scientists noted that rats suffering from the rare degenerative disease had
begun to die six months earlier, even though they had shown no signs of the
disease then.
(A) earlier, even though they had shown no signs of the disease then
(D) earlier without any signs of the disease shown then

This is a very good question as it is written. However, in my personal opinion, the sentence is missing important commas (in red) and an article (in red), just whether we want to be pedantic.

The scientists noted that the rats, suffering from the rare degenerative disease, had begun to die six months earlier, even though they had shown no signs of the disease then.

Back to your question: D is a run-on sentence and they are pretty nasty in terms of grammar, style, usage and meaning on top of that.

This type of sentences go on and on and you do not know the real essence of the sentence itself.

The scientists noted that rats suffering from the rare degenerative disease had begun to die six months earlier without any signs of the disease shown then

The scientists noted that rats suffering from the rare degenerative disease had begun to die six months earlier, even though they had shown no signs of the disease then.

Now, read the first one in a single breath and stop for a second (it does not matter grammar rules, style, which is which): the sentence what is really telling to you ?? what is the real essence of the phrase ?? the answer is : nothing. Aside grammar rules and whatever they are: the language as a whole should say to you what your interlocutor really wants to communicate to you.

It is also true that the GMAT tests you on these aspects of standard English, but is also true that tests you on logic, on the meaning, on what a sentence is trying to convey, the economy of the sentence as a whole.

Now, read in one breath the second one: even though it is not perfect in my opinion (see above what I pointed out), it still communicates in a very efficient way the meaning itself. Notice the comma and the contrast just after it: it works and I would say rather well.

Every student who is studying for this test should keep in mind a broad vision, a context. It is better a sentence with a grammar error but a tomahawk-meaning message to your brain rather a perfect sentence but so convoluted though coherent, without a soul.

Hope this helps.
