Housing construction materials give off distinctive sounds when exposed to high temperatures. Acoustic sensors accurately detect such sounds and fire alarms incorporating acoustic sensors can provide an early warning of house fires, allowing inhabitants to escape before being overcome by smoke. Since smoke inhalation is the most common cause of fatalities in house fires, mandating acoustic-sensor-based alarms instead of smoke detectors will eliminate house fire as a major cause of death. Which of the following, if true, most weakens the argument given?
选项
A、The present high cost of acoustic-sensor-based alarm systems will decline if their use becomes widespread.
B、When fully ignited, many materials used in housing construction give off sounds that are audible even from several hundred yards away.
C、Many fires begin in cushions or in mattresses, producing large amounts of smoke without giving off any sounds.
D、Two or more acoustic-sensor-based alarms would be needed to provide adequate protection in some larger houses.
E、Smoke detectors have been responsible for saving many lives since their use became widespread.
答案
C
解析
本题为Weaken题型,抓住原因中的关键词“sound”来定位,发现(B)、(C)中有关键词“sound”。而(C)指出有些火灾发作但却无声音,断开了两者联接,做出最好的反对,所以(C)正确。
