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.

【选项】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.
