问题 This system has monitor capability covering the entire property, inside and out. Additionally, teachers and parents are vigilant to report persons on the property without a security badge.
选项 A、resourceful
B、committed
C、observant
D、conscientious
答案 C
解析 词义辨析。本题的关键在理解“monitor capability”，显然“Additionally”提供的暗示是老师和家长所做的事(动宾)具有的特质(形容词，副词)和监控系统有类似的功能，因此替换词此处意为“观察机敏的”。
