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?

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.
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, 但是题是不是印错了? 应该是.

Therefor, a wind farm proposed for one of the two counties should

be built in County X rather than in County Y.

nope, since "but the population density of County X is significantly higher than that of County Y", this usually implies that more people are in County X, thus implies that Country Y has more open land since it has less people(at least this is what they are trying to make you think), so it should be bulit in Country Y;

think about this: if I tell you but the population density of China is signifcantly higher than that of America, the first thing pops in ur head is probably "'cause China has more ppl" => "therefore China has less open land" => "therefore China shouldn't bulid wind farm since it doen't have open land"...

usually never question the question itself, for those guys in ETS are getting paid to make up these quesitons...
