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 __________.


(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. Thus lower the cost and increase the profit.
(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. Irrelevant
(C) with the larger number of plants growing per acre, more fertilizer will be required. Irrelevant
(D) with the spacing between rows cut by half, the number of plants grown per acre will almost double.
This is the most attractive wrong answer. The passage already indicates that corns planted this closely will product lower yields per plant. So even if the number of plants per acre will almost double, there is no guarantee that the profits will 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. Irrelevant

C项还是在说in the neighborhood，还是outside the house，错误理解成了in the house
A项意思表明report more≠actually more murders or assaults.过分执著与doubt the conclusion,其实这里A项明显 doubt the premise,从而自然就doubt the conclusion. means people is safe now, do not need to stay in house

错两道题....

1.23‘  54‘  错了。开始没有理解对comprehensive coverage的意思。
A突出了 more comprehensive ,解释了是newspaper加大了范围而不是社会out of control——即使同样的犯罪率，也可能因为跟全面的报道而增多数量。而E中关注的是角色更重要，跑偏。

2.  1’33 题目的最后一句话没看懂。后来反复看了好几遍才理顺...
“The house gecko does not attack the mourning gecko, but in areas where insects congregate it prevents the mourning gecko from feeding on them.”这句话的作用在于解释前一句两地数量差异大。是说HG不攻击MG（这不是数量相差的原因），但MG会因为insects密集，无法捕食而数量减少。所以在城市和郊区的G数量相差很大。D选项解释了为什么城市里insects密集。

3.45' 1.28'
