GWD5-Q28:

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.

答案是E ,但是对这道题目我有疑问，这道题说了X , Y国家有similar terrain, 且 X人口密度大于Y,
similar terrain 指的是什么一样，是地形条件一样，还是国土面积一样呢？所以这里面感觉很不清楚，觉得答案B 也对啊，
说明Y人口总数更大，按照国土面积一样，Y 的人口密度更大，和原文的X人口密度更大就背离了？？？不也weaken了吗？

similar terrain 是指土地面积。B选项与原文中的信息明显相背离，是错误选项。文中规划师的观点是：因为Y县人口密度小，而建风电站需要地方，所以电站应放在Y县。从逻辑上看，weaken对方的观点，是找出对方在前提、假定和推理方面的瑕疵，从而达到削弱对方的目的。但是，基本原则不能把原文中的条件信息给直接否定掉，除非题目暗示这样也可以。B选项是直接否定原文，不可选。要是这样，建风站不需要地方也可以成为选项。

E选项抓住了推理中的漏洞：人口密度小不等于空地多，所以起到了削弱的作用。

similar terrain 指的是相似的地形吧？
