问题 Why does America confront the mineral resources problems?

选项 A、There are few mineral resources in America.
B、Excessive explorations and large consumption have exhausted many resources that are not renew- able.
C、Geographic change and Climate effect.
D、Terrorist has burnt it over.

答案B

解析题目问的是美国何以会遭遇能源问题，这个问题要从根本上找原因，根本原因是过度开采和大量消耗造成的，并非美国的矿藏不丰富，也不是地理和气候的大变动造成的影响，更非恐怖分子焚烧的结果，所以答案为B。
