A newmachine for harvesting corn will allow rows to be planted only fifteen inchesapart, instead of the usual thirty inches. Corn planted this closely will produce lower yields per plant. Nevertheless, the new machine will allow corngrowers to double their profits per acre because __________.
(A)with the closer spacing of the rows, the growing corn plants will quickly forma dense canopy of leaves, which will, by shading the ground, minimize the needfor costly weed control and irrigation
(E)with the closer spacing of the rows, the acreage on which corn is planted willbe utilized much more intensively than it was before, requiring more frequentfallow years in which corn fields are left unplanted
请教各位牛牛 prep的CR部分 有的答案是否有争议？ 谢谢
比如此题
Which of the following most logically completes theargument?
A newmachine for harvesting corn will allow rows to be planted only fifteen inchesapart, instead of the usual thirty inches. Corn planted this closely will produce lower yields per plant. Nevertheless, the new machine will allow corngrowers to double their profits per acre because __________.
(A)with the closer spacing of the rows, the growing corn plants will quickly forma dense canopy of leaves, which will, by shading the ground, minimize the needfor costly weed control and irrigation
(B)with the closer spacing of the rows, corn plants will be forced to grow tallerbecause of increased competition for sunlight from neighboring corn plants
(C)with the larger number of plants growing per acre, more fertilizer will berequired
(D)with the spacing between rows cut by half, the number of plants grown per acrewill almost double
(E)with the closer spacing of the rows, the acreage on which corn is planted willbe utilized much more intensively than it was before, requiring more frequentfallow years in which corn fields are left unplanted
