19.With a record number of new companies starting up in Derderia and with previously established companies adding many 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) Each year, new companies starting up create more new jobs overall than do previously established companies.

(B) Companies established last year will not add a greater number of jobs overall this year than they did 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) This year, the overall number of jobs created by previously established companies will be less than the overall number of jobs lost at those companies.

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

我选的A,答案是C，完全不明白。。

39.The imposition of quotas limiting imported steel will not help the big American steel mills.In fact, the quotas will help "mini-mills" flourish in the United States.Those small domestic mills will take more business from the big American steel mills than would have been taken by the foreign steel mills in the absence of quotas.

Which of the following, if true, would cast the most serious doubt on the claim made in the last sentence above?

(A) Quality rather than price is a major factor in determining the type of steel to be used for a particular application.

(B) Foreign steel mills have long produced grades of steel comparable in quality to the steel produced by the big American mills.

(C) American quotas on imported goods have often induced other countries to impose similar quotas on American goods.

(D) Domestic "mini-mills" consistently produce better grades of steel than do the big American mills.

(E) Domestic "mini-mills" produce low-volume, specialized types of steel that are not produced by the big American steel mills.

我选的B,答案是E,是说mini-mills和big mills的产品不同，所以不会take more business from的意思么？

我帮你解答19题，嘿嘿
题目最后是一句说今年，由于先前已经建立的公司不会像往常一样创造那么多岗位，所以除非今年有很多的新公司成立，他的新岗位的数量才有可能突破往年的数量。然后就问你这样的结论是依据怎样的假设而得出的。
C选项：今年，平均每个新公司创造的岗位不会比以前年度的多
你看，如果这个假设是成立的，那么如果今年要在总体岗位数量上超过去年，而旧公司创造的岗位数量又在减少，那今年就必须要有很多的新公司成立才行，这样，新公司创造的总体岗位数量才可能超过去年的

楼上说的还不是非常的到位，意思当然已经差不多了，这道题，如果提到了旧公司，那么就完全失去了意义了，所以，只能说是新公司，但是题目说，新公司一定要比去年开的多，那么好，他就已经暗示（以这个作为假设）每家新公司不会比去年开的新公司人招的多。给个范例，今年只开了1家新公司，但是去年开了50家，按照作者的理论，那么肯定是要失败了，但是今年万一开的公司招人50000个，去年每家招人只招2个呢？

下面是39题，take more business from的意思是与某样东西有生意的往来，你看E,mini经营的东西，都和big American steel mills不对口，你叫他怎么做生意啊！C个人感觉没有削弱，有点无关！
