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

(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

Nevertheless, the new machine will allow corn growers to double their profits per acre because 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 .

Explanation:

Since the crops are planted closely to each other that the distance between them is too short and at the time of their growing they will quickly form a dense canopy of leaves. the roots will be held closely to each other due to which they will be more firm and the water used for irrigation is well used without any further wastage.

This will reduce the cost of water and of course the use of fertilizer would be limited. This provides more profit than the older techniques and hence increases the profit rate.

overview:

this is a technology-dependent lesson that students can guide at their own pace of exploration and learning. students share what they learn through the use of twitter (or alternative classroom sharing medium like todaysmeet). the use of a social sharing platform like twitter gives students a place for sharing with a wider audience, for more effective means of communication with each other, for incorporating viewpoints from all students in the classroom, and a means to reference thinking and learning by the use of a hashtag at a later time. students will understand the role the allied air forces played in the normandy invasion. teachers can use this as a stand-alone lesson or offer more structure by guiding students through each source, one by one. teachers may learn more about the eighth air force by accessing the abmc’s strategic bombing campaign interactive.
