section 15-7

7. As a result of the ground-breaking work of Barbara McClintock, many scientists now believe
that all of the information encoded in 50,000 to 100,000 of the different genes found in a human
cell are contained in merely three percent of the cell's DNA.

(A) 50,000 to100,000 of the different genes found in a human cell are contained in
merely
(B) 50,000 to100,000 of the human cell's different genes are contained in a mere
(C) the 50,000 to100,000 different genes found ‍in human cells are contained in merely
(D) 50,000 to100,000 of human cell's different ‍genes is contained in merely
(E) the 50,000 to100,000 different genes found ‍in a human cell is contained in a mere

answer: E

我想问一下is contained 得主语是什么呀？information or genes？ 为什么要加the呢？还有in merely和in a mere的区别？

谢谢
