1.       As a result of theground-breaking work of Barbara McClintock, many scientists now believe thatall of the information encoded in 50,000 to 100,000 of the different genesfound in a human cell are contained in merely three percent of the cell’sDNA.
(A) 50,000 to 100,000of the different genes found in a human cell are contained in merely
(B) 50,000 to 100,000of the human cell’s different genes are contained in a mere
(C) the 50,000 to 100,000different genes found in human cells are contained in merely
(D) 50,000 to 100,000of human cell’s different genes is contained in merely（E）
(E) the 50,000 to 100,000different genes found in a human cell is contained in a mere


答案E。哪位能详细解释下这题吗？

A,B, and D前面都没有the，所以不知道这5-10万个dd是不是特指cell中的全部or只是其中的一部分。
剩下E和C，感觉mere是adj，修饰percent n比merely adv要好
而且E表示的是一个cell中的5－10万个genes而C表示的是所有cell中的5－10万个genes。根据常识来讲，貌似前者更符合些吧

我是先排除了A， B， C，因为谓语应该是is， 对应all the information.

然后就纠结了，觉得D/E都不好，E有点罗嗦，D “human cell's" 很奇怪。

谢谢，去复习下定冠词
