A new study suggests that the conversational pace of everyday life may be so brisk it hampers the ability of some children for distinguishing discrete sounds and words and, the result is, to make sense of speech.
(A)it hampers the ability of some children for distinguishing discrete sounds and words and, the result is, to make
(B)that it hampers the ability of some children to distinguish discrete sounds and words and, as a result, to make
(C)that it hampers the ability of some children to distinguish discrete sounds and words and, the result of this, they are unable to make
(D)that it hampers the ability of some children to distinguish discrete sounds and words, and results in not making
(E)as to hamper the ability of some children for distinguishing discrete sounds and words, resulting in being unable to make
题目分析：Aso birsk后面没有that，有的选项加了that，前面说so brisk，后面加that是的前后意思分隔的更清晰，A干掉。B读起来还比较通顺，C后面result of this，这个this是什么，后面又加了they，太复杂了，干掉。D后面加not可是前面已经有hamper（hamper了能力，能力用and连接了两个具体的能力），E being unable实在恶心，干掉。
