Hi,

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

Can someone please check. Thanks.

I Agree! 'A' should be the answer.

(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 - awkward
(C) earlier, no outward signs of the disease had been shown in them, however - awkward
(D) earlier without any signs of the disease shown then - RUN ON
(E) earlier, even though no signs of it were seen in them at that time - seems passive

Ok, In Answer choice A, both the independent clauses using 'had'. (past perfect tense) ? Is this correct?

it should be A
@ anubhavgulati
ya, this is correct.. according to the sentence, first the symptoms of disease need to show up ( past perfect) then the rats begin to die (simple past).. but in the correct portion of sentence we can see that :had begun to die" has been used, then the second verb also need to follow the pattern without any bad effect on the intent of the sentence.
