Wind farms, which generate electricity using arrays of thousands of wind-powered turbines, require vast expanses of open land. County X and County Y have similar terrain, but the population density of County X is significantly higher than that of County Y. Therefore, a wind farm proposed for one of the two counties should be built in County Y rather than in County X.
Which of the following, if true, most seriously weakens the planner’s argument?
A.County X and County Y are adjacent to each other, and both are located in the windiest area of the state.
B.The total population of County Y is substantially greater than that of County X.
C.Some of the electricity generated by wind farms in County Y would be purchased by users outside the county.
D.Wind farms require more land per unit of electricity generated than does any other type of electrical-generation facility.
E.Nearly all of County X’s population is concentrated in a small part of the county, while County Y’s population is spread evenly throughout the country.
题目分析：A说这两个国家挨得比较近，说的是两个国家的地理位置问题，没说过，杀。B说Y的总人口多于X，两个国家人口谁多谁少原文没有涉及，杀。C说Y产的电力外人能购买，扯得远了，杀。D围绕其他产电设备谈的，范围不对，E说的就是人口密度问题，原文谈的就是人口密度和建工厂需要的土地之间的关系，留着。
