    第一次发帖不知道这样对不对ORZ……

          Wind farms, which generate electricity using arrays of thousands ofwind-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 ofCounty Y.  Therefore, a wind farmproposed for one of the two counties should be built in County Y rather than inCounty 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 arelocated in the windiest area of the state.

(B)  The total population of County Y is substantially greater than thatof County X.

(C)  Some of the electricity generated by wind farms in County Y would bepurchased by users outside the county.

(D) Wind farms require more land per unit of electricity generated thandoes any other type of electrical-generation facility.

(E)  Nearly all of County X's population is concentrated in a small partof the county, while County Y's population is spread evenly throughout thecounty.

我的问题是B选项。Y总人口多，题干中又说了X人口密度大，那么人多密度小的Y不就只有一个解释就是很分散吗？我知道E为什么对，但B为什么错呢？

人口密度是单位面积土地上居住的人口数，即人口密度＝人口数/面积。X、Y面积相仿，X的人口密度大，也就是X的人口多，所以B直接就不对了
