单选题 The area is ______ with trails, some as wide as boulevards, that have been cut and maintained by elephants.
A. blackmailed B. latticed C. isolated D. galloped

【正确答案】 C

【答案解析】[解析] C项“isolated隔离的”符合题意，如：Several villages have been isolated by the heavy snowfall．(好几个村庄因大雪与外界隔绝。)其他三项“A项blackmailed勒索；B项latticed装有格子的；D项galloped飞奔”都不正确。本题空格处是说这片区域被一些小路隔开。因此C项为正确答案。
