IMO E.

a , b & c has "are contained". Information is singular.

D "50,000 to 100,000 of human cell’s different genes" is not structured properly. Numbers are pointing to genes.

Hence E.

Subject-Verb disagreement. Only D & E solve this problem. D changes the meaning & is awkwardly constructed. So, E is the winner.

Good question!

I got this wrong because of the article "the".

At first I thought (E) changed the meaning of the original sentence with the addition of "the" in the front, but since this question is specifying a range the original meaning remains intact.

If the sentence gave a quant value then E would've changed the meaning.

e.g.
(A) 50,000 of the different genes found in a human cell are contained in merely
Implies there may be more than 50,000 genes

(E) the 50,000 different genes found in a human cell is contained in a mere
Implies there are only 50,000 genes

This is what threw me off and caused me to eliminate C & E.

(A) 50,000 to 100,000 of the different genes found in a human cell are contained in merely-the information ………………………is contained merely……… OUT-
(B) 50,000 to 100,000 of the human cell’s different genes are contained in a mere -the information ………………………is contained merely……… OUT-
(C) the 50,000 to 100,000 different genes found in human cells are contained in merely -the information ………………………is contained merely……… OUT-
(D) 50,000 to 100,000 of human cell’s different genes is contained in merely- the information encoded in ……human cell’s different genes is , this sentence is ambigious looks like genes are contained but the passage says encoded information is contained OUT-
(E) the 50,000 to 100,000 different genes found in a human cell is contained in a mere


Please correct me if it is incorrect.
