标题: 求解GWD1-Q15

In parts of South America, vitamin-A deficiency is a serious health problem, especially among children. In one region, agriculturists are attempting to improve nutrition by encouraging farmers to plant a new variety of sweet potato called SPK004 that is rich in beta-carotene, 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?

The growing conditions required by the varieties of sweet potato currently cultivated in the region are conditions in which SPK004 can flourish.
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.
There are no other varieties of sweet potato that are significantly richer in beta-carotene than SPK004 is.
The varieties of sweet potato currently cultivated in the region contain some important nutrients that are lacking in SPK004.
There are other vegetables currently grown in the region that contain more beta-carotene than the currently cultivated varieties of sweet potato do.

A:现在种植的sweet potato和 SPK0004 的生长条件相同. CORRECT
B:WEAKEN
C:IR
D:WEAKEN
E:IR

选A. 生产环境不会影响计划。支持。

D 感觉没有A 直接。

D:The varieties of sweet potato currently cultivated in the region contain some important nutrients that are lacking in SPK004.

现在种植的甜土豆含有SPK004所缺乏的一些重要营养.

那么种植SPK004后会造成:该地区的居民会缺乏那些重要营养.会影响计划成功.

所以D有WEAKEN意味.绝对不能考虑.

恩，支持楼上，D 看串了。以为新品种营养丰富呢。

橘生淮南则为橘,生于淮北则为枳：做CR的时候多联系一下实际生活吧，毕竟逻辑在考场上和生活中都是一样的！

C为啥不对啊

作者: guanxi99 时间: 2008-12-29 00:29
对阿.谁解释一下c?如果没有比sk更好的,计划不一定会成功吗.

作者: AlienX 时间: 2008-12-29 13:02
C是無關
小心問題的主幹 ;-)

我也想知道C为什么不可以？为什么无关？

以下是引用guanxi99在2008/12/29 0:29:00的发言：

没有其他更好的选择并不表示SPK400一定会成功哇。

我觉得哦

讨论中的pridiction指的是新品种的种植可以改善当地居民的营养，C说再也没有比新品种含量更丰富的了，新品种含量丰富是改善居民营养的必要条件而不是充分条件，就是说含量丰富不能必然导致改善居民营养的结果。虽然没有Weaken但也没有Support的作用。

不知道有没有说清楚。。。。嘿嘿

我认为D是无关

我觉得C更相关啊 C. There are no other varieties of sweetpotato that are significantly richer in beta-carotene than SPK004 is. 因为目的就是补充VA 也就是BETA啊

最后一句话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.
中 the plan has good chances of success.是结论。答题点是找其他原因，也能表达对结论支持的观点。A the condition can flourish the growing of the S，thus support the conclusion.
C有表达出对结论的任何作用吗？再回读一下肯定没有啊不要被误导啊
