GWD5-28 (CD3-28)

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?

1. County
                       X and County
                           Y are adjacent to each other, and both are located in the windiest area of the state.

2. The total population of County
                           Y is substantially greater than that of County
                               X.

3. Some of the electricity generated by wind farms in County
                           Y would be purchased by users outside the county.

4. Wind farms require more land per unit of electricity generated than does any other type of electrical-generation facility.

5. 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B，但我在B/E之间犹豫不决 --- 更倾向于E --- E是说Country Y人口分布平均，那么征地和施工难度更大，对居民影响更大才对呀？而B只不过是Y的人多，并不能说明X人少就更好施工啊？
