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?
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
上述两句我觉得B和E能推出同样的结论,请教。
谢谢cranberry
根据上面的那个简单公式,X、Y两地领土相同,Y的人口数量大于X的人口数量。正常情况下,Y的人口密度应该同样大于X。但是Y的人口密度反而小于X的人口密度,这说明X的人口分布存在异常,也可以推出类似E的内容。
当然,E是更完美的选项,我做的时候也选的是E,但是我现在的问题是拿不出足够的理由排除B,请指出我的逻辑错误,谢谢。
啊,明白了,刚才被绕住了,谢谢斑竹。
terrain,这里是什么意思,应该是指地形吧!有没有面积的意识?
from wb
1 a (1) : a geographic area (2) : a piece of land : GROUND b : the physical features of a tract of land
2 : TERRANE 1
3 a : a field of knowledge or interest : TERRITORY b : ENVIRONMENT, MILIEU
我看到b就选了,因为当时认为similar terrain就是面积什么都一样,
现在看来应该是指地形,否则b说Y人多,那么地形又一样不是density就高了吗?
现在看来e是对的,原文说要大片土地,x density大---〉在y建wind farms
e说x的人口density虽然大,但都集中small part of the country,这个weaken即是他因(concentration)削弱,又是断桥( density 于open land的多少无关)削弱。
首先,原文根本没有提及面积;有的仅仅是地形相似,X人口密度大于Y。
A:排出他因削弱,加强
B:Y人口巨大,人口密度又很小,说明大广人稀,正好风力发电,支持
C:would be purchased by users outside the county,无关,讨论的不是发电以后卖给谁
D:than does any other type of electrical-generation facility,错误比较
E:X人口集中,可以给发电提供空间,削弱
此题如果将B选项改一下,变成The total population of
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
