6.     F: We ought not to test the safety of new drugs on sentient animals, such as dogs and rabbits. Our benefit means their pain, and they are equal to us in the capacity to feel pain.

G: We must carry out such tests; otherwise, we would irresponsibly sacrifice the human lives that could have been saved by the drugs.

Which of the following, if true, is the best objection that could be made from F’s point of view to counter G’s point?

(A) Even though it is not necessary for people to use cosmetics, cosmetics are also being tested on sentient animals.

(B) Medical science already has at its disposal a great number of drugs and other treatments for serious illnesses.

(C) It is not possible to obtain scientifically adequate results by testing drugs in the test tube, without making tests on living tissue.

(D) Some of the drugs to be tested would save human beings from great pain.（E）

(E) Many tests now performed on sentient animals can be performed equally well on fertilized chicken eggs that are at a very early stage of development.

答案E也没有反对G的意见阿？A为什么不对阿？因为

E还是要进行那种试验阿？

7.     Which of the following best completes the passage below?

The unemployment rate in the United States fell from 7.5 percent in 1981 to 6.9 percent in 1986. It cannot, however, be properly concluded from these statistics that the number of unemployed in 1986 was lower than it had been in 1981 because______

(A) help-wanted advertisements increased between 1981 and 1986

(B) many of the high-paying industrial jobs available in 1981 were replaced by low-wage service jobs in 1986, resulting in displacements of hundreds of thousands of workers

(C) in some midwestern industrial states, the unemployment rate was much higher in 1986 than it had been in 1981

(D) the total available work force, including those with and without employment, increased between 1981 and 1986（D）

(E) the average time that employees stay in any one job dropped during the period 1981 to 1986

问：the total available work force和题目中的unemployment有什么关系阿？

我觉得第6题的A没有提出对狗和兔子等动物进行试验的直接有力的反驳,它只在陈述用动物做试验的事实.所以不能作为F'对G'的反驳.而E中提出可以用鸡蛋做试验,反驳了G'所谓的如果不用狗或兔子做试验,人类就会牺牲的说法.

jaccicywoo

the total available work force 就是劳动力的数量. unemployment 和employment 加起来就是the total available work force,要算失业率当然要知道三者中的两者. 失业率=UNemployment/UNemployment+Emplpyment,如D所说,UNemployment 和EMployment 都增长的情况下,不能确定UNemployment是否比Employment 少.
