OG verbal分册逻辑第九题
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 newvariety of sweet potato called SPK004 that is rich in betacarotene, which thebody converts into vitamin A. The planhas good chances of success, since sweet potato is a staple of the region’sdiet and agriculture, 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 growing conditions required by the varieties of sweet potato currently cultivated in the region are conditions in which SPK004 can flourish.
B. The flesh of SPK004 differs from that of the currently cultivated sweet potatoes incolor and texture, so traditional foods would look somewhat different when prepared from SPK004.
C. There are no other varieties of sweet potato that are significantly richer inbeta-carotene than SPK004 is.
D.The varieties of sweet potato currently cultivated in the region contain some important nutrients that are lacking in SPK004.
E. There are other vegetables currently grown in the region that contain more beta-carotene than the currently cultivated varieties of sweet potato do.
我选的是C,正确答案是A,看过后面的解释后,我大致明白A了,不过我对于C的解释有点没看懂,望高手解释一下!
解释是这样的“It is SPK004's beta-carotene content relative to the beta-carotene of the sweet potatoes currently grown in the region that is relevant here, so it does not matter if there are other varieties of sweet potato that are richer in beta-carotene than SPK004 is. ”
E. none of the people who conducted the research were employees of the FoodBasket supermarket
答案是A,但是我没读懂。是说顾客会固定买他们喜欢的东西,所以去低价超市也不会花更少钱。是这样吗? |
