求教 新prep rc1 102

102.   (GWD 1-Q15)

In parts of South America, vitamin-A deficiency is a serious health problem, especially among children.  In one region, agriculturists hope to improve nutrition by encouraging farmers to plant a new variety of sweet potato called SPK004 that is rich in betacarotene, which the body converts into vitamin A.  The plan has good chances of success, since sweet potato is a staple of the region’s diet and agriculture, and the varieties currently grown contain little beta-carotene.
Which of the following, if true, most strongly supports the prediction that the plan will succeed?
A. There are other vegetables currently grown in the region that contain more beta-carotene than the currently cultivated varieties of sweet potato do.
B. The flesh of SPK004 differs from that of the currently cultivated sweet potatoes in color and texture, so traditional foods would look somewhat different when prepared from SPK004.
C. For successful cultivation of SPK004, a soil significantly richer in nitrogen is needed than is needed for the varieties of sweet potato currently cultivated in the region.
D. There are no other varieties of sweet potato that are significantly richer in beta-carotene than SPK004 is.
E. The currently cultivated varieties of sweet potato contain no important nutrients that SPK004 lacks.

正确答案为E  可我选了D

请nn指教解题思路和DE选项的对应题目要求的区别~

contain no important nutrients that SPK004 lacks

太纠结了,就是说Sweet potato包含了SPK004缺失的不重要的营养.就是说重要的营养都在吧?

E说的是还有其他植物比当前种的sweet potato含的 beta-carotene多,这对该计划SPK004 的种植是否会去的成功没有影响,注意结论的特殊性和具体性

The growing conditions required by the varieties of sweet potato currently cultivated in the region are conditions in which SPK004 can flourish.

There are no other varieties of sweet potato that are significantly richer in beta-carotene than SPK004 is.其他西红柿含不含那种物质对该计划的成功不产生影响
