单项选择题
The underlined word "fragile" in the last paragraph is closest in meaning to ______.
A．inefficient
B．easily broken
C．poorly planned
D．involuntary
答案
参考答案：B
解析：[分析] 词义题型。 见最后一段第二句中的opportunistic(机会主义的)，第三句的后半句…“ breaks down when the common means cease to aid each party in reaching its goals．(由此可推断出：easily broken)；此外，此词应是loose的近义词；由此得出此词应有“脆弱，松散”之意，因此选项B是答案。
