597. A company has developed a new sensing device that, according to the company’s claims, detects weak, ultralow-frequency electromagnetic signals associated with a beating heart. These signals, which pass through almost any physical obstruction, are purportedly detected by the device even at significant distances. Therefore, if the company’s claims are true, their device will radically improve emergency teams’ ability to locate quickly people who are trapped within the wreckage of collapsed buildings.
Which of the following, if true, most strengthens the argument?
A. People trapped within the wreckage of collapsed buildings usually have serious injuries that require prompt medical treatment.
B. The device gives a distinctive reading when the signals it detects come from human beings rather than from any other living beings.
C. Most people who have survived after being trapped in collapsed buildings were rescued within two hours of the building’s collapse.
D. Ultralow-frequency signals are not the only electromagnetic signals that can pass through almost any physical obstruction.
E. Extensive training is required in order to operate the device effectively.
题目大意
一家公司开发了新的传感装置，按照公司的说法，可以检测与心跳相关的微弱而且超低频的电磁信号。这些能穿过任何物理障碍的信号，据说会被装置检测到，即使有明显的距离。因此，如果这个公司的说法是真的，他们的装置会彻底的提升搜救队快速定位被困在倒塌建筑物废墟中的人的能力。
解题思路
问题问下面选项如果是真的，哪个最能加强原文，也就是选项要说这个装置确实很有效，要再找一些优点。
A：被困在废墟里的人经常会严重受伤，需要及时的治疗。错，原文主要说检查装置，和被困人员需要治疗没有关系。
B：这个装置会给出独特的标志，当它检测到信号来自人类而不是其他生物。正确，又找到了一个优点，能分辨人和其他生物就不会误判，不用浪费时间。
C：大多数从废墟中生还的人都是在建筑物倒塌后两小时内被营救的。错，只说人需要在2小时内被救出，没有说装置能否快速检测到人。
D：超低频信号不是唯一可以通过几乎任何物理障碍物的电磁信号。错，信号的种类与原文无关。
E：为了有效的操作这个设备，需要有广泛的训练。错，操作者的技能培训与原文无关。
答案：B
