此题如果将B选项改一下,变成The total population of laceType w:st="on">CountylaceType> X is substantially greater than that of laceType w:st="on">CountylaceType> Y对不对呢?

简单哦
X 的人都在一个旮旯里, 所以留下大片土地,正好符合require vast expanses of open land
Y 分布的均匀的,
Terrain大意表示2国有相同的地形\势…勿以中文来理解英文…………
density=population/terrain
County X and County Y have similar terrain, but the population density of County X is significantly higher than that of County Y.
The total population of County Y is substantially greater than that of County X????
算错了.D=P/T. T是定数.-->D与P正函数关系.题中告诉我们Dx>Dy,所以是Px>y.而非Y的人口多
