PREP1的逻辑问题~

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.

答案是E。
文章：南非缺乏VA。某地，农学家希望通过鼓励农民种植SPK004甜土豆（有很多beta，可以在人体内转换成VA）来改善营养情况。这个计划很可能成功，因为甜土豆是当地的主要食物，并且挡墙有的这些种类中很少有beta。
下面哪一个可以说明这个计划会成功？
E．现在种植的甜土豆 包含 没有 重要营养，SPK004缺乏的。（没有包含重要的营养，这些营养是SPK004也缺乏的。）

呃- -？为什么是这个答案。。- -~p.s.我觉得没有一个答案是对的。。。

108.      (GWD 7-Q41)

Magazine Publisher:  Our magazine does not have a liberal bias.  It is true that when a book review we had commissioned last year turned out to express distinctly conservative views, we did not publish it until we had also obtained a second review that took a strongly liberal position.  Clearly, however, our actions demonstrate not a bias in favor of liberal views but rather a commitment to a balanced presentation of diverse opinions.
Determining which of the following would be most useful in evaluating the cogency of the magazine publisher's response?
A. Whether any other magazines in which the book was reviewed carried more than one review of the book
B. Whether the magazine publishes unsolicited book reviews as well as those that it has commissioned
C. Whether in the event that a first review commissioned by the magazine takes a clearly liberal position the magazine would make any efforts to obtain further reviews
D. Whether the book that was the subject of the two reviews was itself written from a clearly conservative or a clearly liberal point of view
E. Whether most of the readers of the magazine regularly read the book reviews that the magazine publishes

答案是C。
文章：出版社：我们的杂志并没有自由偏见。我们去年委托的一本书的review表达了明显的保守观念，我们没有出版它，直到我们又得到了这本书的第二个支持自由立场的review。很明显，我们的行为证明了我们并没有特别喜欢自由观点反而是一种不同观点的平衡。
C．是否，在这次事件中，第一个review有很明显的自由立场，--？？不会翻译。。看不懂这个选项。。position是做obtain的宾语么？那further reviews又是谁的宾语呢。。这句话啥意思。

C应该按一下方法解读：

注意“Whether in the event
           that a first review commissioned by the magazine takes a clearly liberal position
           the magazine would make any efforts to obtain further reviews” that... 是做event的同位语。

原文：缺乏VA，现在要增加营养，计划种SPK004，这东西能增加VA
求support
E---SPK004不会缺乏别的营养---也就是说，不会存在VA是增加了，结果其他

营养物质不够了的情况

= =能不能。。再详细地分析一下句子。。

E的意思难道不是
目前已培育出的各式甜土豆中没有一种含有SPK004缺少的重要营养…？

Quadrifolia

对阿，所以说白了就是现在用的土豆中有的营养，新品种也都有了，所以就不用担心使用新品种会有别的种类的营养缺失了

108的意思我百度了下~解释的很好~
杂志出版社的意思是，他们没有自由主义的偏向。这是核心意思。

下面是解释，如果书评属于保守主义了，那么他们就不出版，直到得到了自由主义式的书评。
但这并不代表杂志就偏向自由主义。
杂志追求的是一种平衡。
（这就暗示---，如果杂志得到的是自由主义书评，那也会找到保守主义书评后，再出版。）


答案C的意思，就是 如果最终杂志得到的是自由主义书评，那他们会不遗余力地继续找（保守主义）书评。
