B．A hurricane watch is more serious than a hurricane warning.
C．Falling air pressure is an indicator that the storm is increasing in intensity.

网考网参考答案：C
网考网解析：
根据最后一段倒数第三句话“People living in low-lying areas are wise to evacuate their houses because of the storm surge，which is a large rush of water that may come ashore with the storm．”可知storm surge是指水而不是风，所以A不正确。根据最后一段开头的描述，飓风可能登陆时先在一个较大的可能范围内进行hurricane watch，然后在可能着陆点hurricane warning，可以看出 hurricane warning 比 hurricane watch更严重，B不正确。根据第三段最后一句“People often lose their lives by leaving shelter when the eye has arrived，only to be caught in tremendous winds again when the eye has passed．”，当风眼来临时人们如果走出房间会被风眼过去后的大风吹死，所以说在风眼来临时走出房间是不安全的，D也不正确。虽然文章中没有直接说，但通过排除法可以知道只有C是正确的。 查看试题解析出处>>
