Q28(D)
Wind farms, which generate electricity using arrays of thousands of wind-powered turbines, require vast expenses 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?
County X and County Y are adjacent to each other, and both are located in the windiest area of the state.
The total population of County Y is substantially greater than that of County X. Some of the electricity generated by wind farms in County Y would be purchased by users outside the county. Wind farms require more land per unit of electricity generated than does any other type of electrical-generation facility. 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.为什么选D
I choose E instead. If E, "Nearly all of County X’s population is concentrated in a small part of the county", is true, then X has more open land than Y, and it will make more sense to build the wind farms in X rather than Y -- the planner's argument is weakened. Therefore, E is the best answer.
Open to discussions.
