问题 What is the cause of the problem that people living on parts of the south coast of England face?
It is not feasible to build sea defenses to protect against erosion because______.
选项 A、house agents along the coast do not support the idea
B、it is too costly and will endanger neighboring areas
C、the government is too slow in taking action
D、they will be easily knocked down by waves and currents
答案B
解析 根据文章第二段的"New sea walls cost hundreds of millions of pounds and would merely make the waves and currents go further along the coast，shifting the problem from one area to another"可知，修建新的海上防御墙不仅耗资巨大，而且会使海浪沿海岸线移动，将问题从一个区域转移到另一个区域，由此可见，修建防御墙的建议并不可行，因此只有B符合题意。另外，从文章中无法推出"house agents along the coast"的态度，因此A不符合题意。从文章中我们可以看出政府也采取了行动，派出了"surveyors"进行考察，因此说政府"too slow in action"证据不足。文章说修建防御墙的计划不可行不是因为它容易被"break down"，而是因为它会"make the waves and currents go further along the coast，shifting the problem from one area to another"，所以D也不符合题意。
