GWD1-Q15:
In partsof South America, vitamin-A deficiency is aserious health problem, especially among children. In one region, agriculturists are attemptingto improve nutrition by encouraging farmers to plant a new variety of sweetpotato called SPK004 that is rich in beta-carotene, which the body convertsinto vitamin A. The plan has goodchances of success, since sweet potato is a staple of the region’s diet andagriculture, and the varieties currently grown contain little beta-carotene.
Which ofthe following, if true, most strongly supports the prediction that the planwill succeed?
A. The growingconditions required by the varieties of sweet potato currently cultivated inthe region are conditions in which SPK004 can flourish.
B. The flesh of SPK004 differs from that of thecurrently cultivated sweet potatoes in color and texture, so traditional foodswould look somewhat different when prepared from SPK004.
C. There are no other varieties of sweet potato thatare significantly richer in beta-carotene than SPK004 is.
D. The varieties of sweet potato currentlycultivated in the region contain some important nutrients that are lacking inSPK004.
E. There are other vegetables currently grownin the region that contain more beta-carotene than the currently cultivatedvarieties of sweet potato do.

答案是A~为什么不选C呢~我觉得现在的growing condition 适合新品种不能加强，相比之下C中没有别的potato有更丰富的beta-carotene更能加强吧~大家讨论下吧~

C是gmat逻辑中的常见错项，你不觉着它和题干是无关的吗？本来说的是SPK004，再扯上别的东西干嘛？没有其它的东西富含β胡萝卜素无助于支持题干啊。
题目只是问你哪一条可以加强题干。你只需要找一个可以使上述计划获得成功的选项就好了。
