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
(B) earlier, but they were not showing no signs of the disease then
(C) earlier, no outward signs of the disease had been shown in them, however
(D) earlier without any signs of the disease shown then
(E) earlier, even though no signs of it were seen in them at that time

(E) earlier, even though no signs of it were seen in them at that time

IMO A.
B changes the meaning "not showing no signs"=> there were signs. "however"is misplaced in C.
In D "had begun to die without" is not clear, without modifies die. I would avoid passive in E.

I will go with E, as we already have a HAD in non underlined portion to reflect 2 time periods.

I would chose E.
Basic Question: Why few options has then at the end of A, B and D? Does is holds any meaning or rule in grammar?

my dear "it" is singular pronoun ."rats" is plural so "it" is referring to degenerative disease

make sense ?

isn't 'they' ambiguous? can't it refer to rats or scientists?

Expert's post
I wouldn’t entertain any doubts about the pronoun in the close - running choices A and E. After all, the disease is all about the rats and not about the scientists. In E also, there is no doubt about ‘it and them ‘(not they as somebody has pointed out; there is no ‘they’ in that choice at all) And such touch and go reference is the basis of the modern day pronoun - based questions. If one cannot logically see through the reference, it is going to be difficult
But the only difference I see between A and E is that both arms of the sentences are in active voice in A, while they are in active- passive mode in E. But I wouldn’t know whether GMAT will test a question on such trivial grounds alone
