OG verbal分册逻辑第九题

Summer婵

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. ”

plan的目的是要improve nutrition，A选项说growing condition能使SPK004好好长，如此plan才有可能成功

C的解释是说这里相关的是SPK004与目前种的那个甜土豆的betacarotene谁多谁少，跟有没有其他品种的甜土豆含有更多的betacarotene无关

个人理解哈……

OG的解释其实很精华这里，它的意思是只有现在在这个地区被培植的西红柿是有关的！所以其他种类的存在是无关的（因为文章和选项都没说这个其他种类是在讨论的这个范围生长的）
PS：延伸一下，这里OG说的比较模糊，其他的种类存在是无关的...退一步说，如果往前推一步说其他种类就是在这个地区长的，也是无关的，因为你不知道这些种类适不适应这里的土壤等等的因素！题目给的条件不够，而且，在推出结论的逻辑链里面，文章已经写了这个地区木有其他的种类含有这个可以转换维他命A的东东，所以这个没有其他种类这个东西是已经被文章assumed了的

逻辑链是: sweet potato是主食而且现有的potato缺乏 beta-carotene  → plan 成功率高（ 改种SPK004 可以提高营养）
答案A 是 说 growing conditions 适宜SPK  直接support 了结论
答案C ， 因为support 是针对结论的， 比较其他品种的 beta-carotene 含量并没有增强 结论说明种SPK可以提高nutrition。 是无关选项~~

我刚刚比较了一下五个选项，发现只有C选项是没有注明 in the region的，不知道这算不算一个很细微的区别？但是我又看了看全文，觉得即使没有标明in the region, 应该也是默认这些其他种类的sweet potatoes就是在这个地区，恩，这个选项应该是像你说的已经被文章assumed的了。
另：little的意思到底是没有，还是有一点（但很少）？？
还有。。。。。能给我翻译一下那个C选项的OG解释嘛。。。。我理解起来还是乖乖的。。。。

恩，我觉得说的很简单明了，有道理，但是是不是同时这个条件已经是原文存在的assume了，所以也不能选？
另外，我看OG 的解释，这里的结论说的success of plan是说通过鼓励农民种植，来达到提高营养的目的。农民愿不愿意种这个SPK很关键。

题目的premise  说“现在的varieties的beta-carotene 含量少”，所以捏比较含量有强调premise 之嫌木有加强结论，可以说是一种assumption吧。        
只要增强success of plan 可以算作是增强结论，所以我觉得农民愿意种 也口以加强的。

C 是无关选项。

这种题不能想太多，要把想象力限定在一个框架内。
