参考解答
正确答案:C
事实细节题。A选项中提到北极熊因为饥饿而闯入村庄——colllingintovillage,这个在原文中没有信息提到,所以排除。B选项中的spendtheirlivesonland帮助我们定位到原文的第三段开头——polarbearsCan’tsurviveforlongonland.与选项意思正好相反,所以排除。原文第二段最后一句Thatmaycausetwo-thirdsoftheword’s20,000polarbearstobegonebythentoo.及前一句…theArcticcouldbefreeofsummerseaiceby2050与C选项信息一致。原文第四段第三句话Thebearsmustswimlongerdistancesbetweenicepacks(大片浮冰),andtheycan’talwaysmakeit.与D选项中notaproblem意思相左,因此排除。故选C。
