【正确答案】 C

【答案解析】根据原文最后两句，Already they have succeeded where statesmanship has failed．Although unable to speak the some language，the inhabitants of this embattled planet have at least agree to wear the same pants(它们已获得了政治家们不能达到的成功。虽然不能说同一种语言，但至少这个处于防御状态的星球上的居民已同意穿同一类型的裤子了。)这儿暗示政治家们就许多全球问题未能达成一致。因此C为正确选项。
