问题 According to the passage, electric response audiometry can be used ______.
According to the passage, testing team at the University of Iowa is the first to ______.

选项 A、develop a method to test hearing by way of the brain
B、determine the extent of brain damage in hearing-impaired persons
C、observe the reaction of the brain to a laboratory-controlled noise
D、study all the parts of brain-wave responses at the same time

答案D

解析 此题为特定信息查寻题。本题所问是关于文章细节的问题,虽然文中没有直接回答,但是通过"...the University of Iowa specialists are the only scientists to date who analyze simultaneously three components of hearing..."(衣阿华大学的专家们是绝无仅有的同时分析听力三个部分的科学家)中的“only”(仅仅,唯一),“analyze”(分析),“simultaneously”(同时地)和"three components of hearing"(听力三个部分)可以判断出D为正确答案。A项、B项和C项均与原文不相符。
