She conducted an experiment in which people were filmed by thermal-imaging cameras tryingto find their way out of a large【C8】______ room. It【C9】______them nearly four minutesto find the door【C10】______a sound alarm, but only 15 seconds with one.
Withington studies how the brain【C11】______ sounds at the university. She says that the【C12】______ of a wide band of frequencies can be pinpointed more easily than the source of anarrow band. Alarms【C13】______the same concept have already been installed on emergency vehicles.
The alarms will also include rising or falling frequencies to indicate whether people should goup【C14】______ down stairs. They were【C15】______ with the aid of a large grant from BritishNuclear Fuels.
【C5】
选项
A、noise
B、sound
C、music
D、bell
答案
B
解析
句子的前半句有a wide range of frequencies,发出来的应该是sound,而不是令人烦躁的noise。用music或bell都有些突然,与上下文的意思不连贯。
