2(Z). With a record number of new companies starting up in Derderia, and with previously established companies adding many new jobs, a record number of new jobs were created last year in the Derderian economy. This year, previously established companies will not be adding as many new jobs overall as such companies added last year. Therefore, unless a record number of companies start up this year, Derderia will not break its record for new jobs created.



Which of the following is an assumption on which the argument relies?



A.In a given year, new companies starting up create more new jobs on average than do previously established companies.

B.The number of people seeking employment is no larger this year than it was last year.

C.This year, the new companies starting up will not provide substantially more jobs per company than did new companies last year.

D.Previously established companies in Derderia will be less profitable this year than such companies were last year.

E.The number of jobs created in the Derderian economy last year was substantially larger than the number of jobs lost.

6.(Z)Agricultural societies cannot exist without staple crops. Several food plants, such as kola and okra, are known to have been domesticated in western Africa, but they are all supplemental, not staple, foods. All the recorded staple crops grown in western Africa
were introduced from elsewhere, beginning, at some unknown date, with rice and yams. Therefore, discovering when rice and yams were introduced into western Africa would establish the earliest date at which agricultural societies could have arisen there.



Which of the following is an assumption on which the argument depends?



A.People in western Africa did not develop staple crops that they stopped cultivating once rice and yams were introduced.

B.There are no plants native to western Africa that, if domesticated, could serve as staple food crops.

C.Rice and yams were grown as staple crops by the earliest agricultural societies outside of western Africa.

D.Kola and okra are better suited to growing conditions in western Africa than domesticated rice and yams are.

E.Kola and okra were domesticated in western Africa before rice and yams were introduced there.

9．To protect certain fledgling industries, the government of Country Z banned imports of the types of products those industries were starting to make. As a direct result, the cost of those products to the buyers, several export-dependent industries in Z, went up, sharply limiting the ability of those industries to compete effectively in their export markets.



Which of the following can be most properly inferred from the passage about the products whose importation was banned?



(A)Those products had been cheaper to import than they were to make within Country Z's fledgling industries.

(B)Those products were ones that Country Z was hoping to export in its turn, once the fledgling industries matured.

(C)Those products used to be imported from just those countries to which Country Z's exports went.

(D)Those products had become more and more expensive to import, which resulted in a foreign trade deficit just before the ban.

(E)Those products used to be imported in very small quantities, but they were essential to Country Z's.

原文什么个意思 能不能帮忙梳理下   还有为什么选C

原文的大致意思是：去年D地新建了大量新公司，这些新公司新添了很多新工作，因此D地总共的新工作增加了。
                今年，D地于去年建成的公司添加的工作比去年少。
                除非D地今年新开的公司数很多，否则今年总计的新增工作数就不会超过去年。
选C的原因是：必须排除今年新开公司可能会creat很多new jobs，即招收人数比去年新开公司招人多。否则，这些new jobs的数量就会弥补由于旧公司找人少和新开公司少的不足。

这道题我也纠结了很久，选不出，但可以肯定B不对，因为文中已经明确指出"all the recordede staple crops grown in western Africa were introduced from elsewhere.",这已是既定的事实，即evidence，我们所要攻击或加强的是逻辑链，而非事实。
A的句子我也没看懂，通过答案倒推可能这么理解：西非的人并未开发这样一种staple crops, 这种crops是rice and yam一引进来人们就停止耕种的。也就是说排除这样一种staple crops的可能。（这样总结后，发觉自己以前的几个思路是错的~）

原文说：Z为了保护某新兴产业，采取限制进口同类产品的政策。然而这样会导致这类产品价格上升，从而需求者的制造成本上升，即本国一些出口企业需求该产品，成本上升导致这些出口企业的全球市场竞争力下降。
很明显选A，因为只有进口的产品价格低，限制进口后该产品的价格才会升高，即限制后市场上流通的有本国新型工厂生产出来的高价产品。
（为了更好理解，举个现实中的例子，我国生产的廉价商品进入美国市场后，使得它们某些新兴产业得不到发展，于是美国政府采取贸易保护政策，限制我国产品进入，也就是所谓的贸易壁垒。那么他们这样做的结果是，美国市场的该产品价格上升，导致其某些出口企业竞争力受影响。）

不知道解释的怎么样呢~希望逻辑能够更上一层楼~大家都加油努力吧！

自己顶一下啦

自己修正一下啦~对于Agricutural societies这道题至今已有很多种解释的版本，但究竟是哪种暂无定论。因为没有官方解答，大家都是基于对答案倒推后题目选项的理解，各有各的说法。

1.就是我上文中解释的，排除这样一种Staple crops的可能。

2.

choice A.
This is of the form, if not A then not B
A->staple crops
B->agricultural societies
In this argument, rice and yams are assumed as examples of the staple crops mentioned earlier. Using this, a conclusion is drawn that if it can be known when rice and yams were introduced, it could also be known when the agricultural societies in western Africa were established.

This is based on the assumption that rice and yams were the first staple crops in W.A. Choice A clearly states that


3.

IMO A.
It is said that along with rice and yams all staple crops got introduced there. But it may be the case that during same time when rice and yams got introduced, African ppl cud hav developed crop which they used to cultivate into staple crops.
A states that so A shd be answer.

有没有哪位高人能说明到底哪个说法是对的呀~！！

Let me try~lol~
A:
It is assumption question; therefore, if I eliminate the not, the sentence  will be a weaken form---People in western Africa did develop staple crops that they stopped cultivating once rice and yams were introduced.

The staple crops had already existed  in the western Africa, before the rice and yams were introduced. Thus, "establish the earliest date of the staple crop"  does not supported any more.

Is that right?
