14.   Some analysts maintain that an embargo by country Litora on the export of a strategic metal to country Zenda, if imposed, would drive up the price of the metal in Zenda at least tenfold. They note that few other countries export the metal and that, with an embargo, Zenda might have to depend on as-yet-unexploited domestic sources of the metal.

Which of the following, if true, constitutes the most serious objection to the analysis above?

(A) Litora’s economy depends heavily on foreign currency earned by the export of the strategic metal to other countries.

(B) There are foreign-policy steps that Zenda could take to appease Litora and avoid being subjected to an embargo on the metal.

(C) Geologists believe that additional deposits of the metal could possibly be found within the laceType>territorylaceType> of laceName>LitoralaceName>.

(D) Only a small proportion of Zenda’s import expenditures is devoted to the import of the metal from Litora.（E）

(E) In case of an embargo, Zenda could buy the metal indirectly from Litora on the world market at a less than one-third increase in cost.

What's difference between (B) and (E)?

Thanks for your reply!!!!

题干问的是OBJECTION THE ANALYSIS ABOVE.

原文分析的结果包括：1, Z国金属价钱至少上涨10%；2,Z国只能依靠自己国家资源；等。

B没有反对上文中任何一个。

E加强了1，反对了2，所以还是反对原文。

thanks for your reply!

I understand now

不太明白，选E难道不是因为原文analysis中说"with an embargo"吗？

文章这么推论的--> Some analysts maintain that an embargo by country Litora on the export of a strategic metal to country Zenda, if imposed, would drive up the price of the metal in Zenda at least tenfold.和EVIDENCE few other countries export the metal

---->推出Zenda might have to depend on as-yet-unexploited domestic sources of the metal.

E说封就封啊,我直接上市场去买，就是走零售不走批发了，价格不过贵了1/3, 怎么可能会有10倍之多，断桥削弱么，原文的条件不对，结论当然就推不出.

who can help me?

此类前提结论性削弱是应该建立在:承认前提,反对结论的基础上的.即:使前提条件为必要条件.否则,反对前提,那该种削弱就没有意义了.
