试题详情

题目:

Which of the following most logically completes the argument?
 
A new machine for harvesting corn will allow rows to be planted only fifteen inches apart, instead of the usual thirty inches.  Corn planted this closely will produce lower yields per plant.  Nevertheless, the new machine will allow corn growers to double their profits per acre because __________.

选项:

A、with the closer spacing of the rows, the growing corn plants will quickly form a dense canopy of leaves, which will, by shading the ground, minimize the need for costly weed control and irrigation
B、with the closer spacing of the rows, corn plants will be forced to grow taller because of increased competition for sunlight from neighboring corn plants
C、with the larger number of plants growing per acre, more fertilizer will be required
D、with the spacing between rows cut by half, the number of plants grown per acre will almost double
E、with the closer spacing of the rows, the acreage on which corn is planted will be utilized much more intensively than it was before, requiring more frequent fallow years in which corn fields are left unplanted

答案:

A

提问:

原文说的是产量减少了但是利润能增加。A说的是成本,很多题目里面说要提高利润,如果选项中只提到了成本基本都不对。所以选了D,种的更多了可以卖的更多。

提问:

请教Tina老师,这道题我比较困惑于B和D。B我可以姑且认为玉米变高和利润没关系(有的人可能还认为高玉米不好呢),但D选项真的不是太理解,我觉得D选项更能很好地契合double,产量增加了一番,profits也增加了一番,很有道理啊。。请老师解答,谢谢!

提问:

我拿到题目,理解了题意,看到题干说了closely会yield lower,我做题第一反应就是必须证明是否已经达到了这个界定范围-100 inches apart和99 inches apart并不会影响产量,所以题干中没有给出一个界定范围,也许选项中会给出也说不定-预判(!!老师说逻辑题尽量不要自我预判方法-危险,至少assumption唯一方法取非驳斥,其他方法都不可以);D我脑补了1)没有说达到某个界定范围,Plants增多并没有Lower yield per plant-可能收入会接近俩倍, 2)脑补了类似fixed cost概念,至少每亩土地的成本是不会变的,就是有些成本不管产量多少都固定不变,则俩个因素同时作用Profits达到俩倍也是可能的;A粗糙的看就是对的;老师说了因为成本大量下降,则利润双倍,但是rev没有说,其实逻辑也没有那么严密;如果A的逻辑不严密可以选,D也差不多;排除D的原因,老师说这个观点是almost,就是没有达到俩倍。(我没有想抬杠,但是我当时做题的时候感觉AD俩个我纠结了,我自己错题整理时候也说了A没有不对,但是,AD比较,D的选项信息和原文题干相似度更高,且信息量更少;A中给出新的信息比较多,可能风险比较大…我就选了D;D说了plants就almost double,但仍然不讨论是否yield per plant是否会变化,这也是合理的;
