12. Purebred dogs are prone to genetically determined abnormalities. Although such abnormalities often can be corrected by surgery, the cost can reach several thousand dollars. Since nonpurebred dogs rarely suffer from genetically determined abnormalities, potential dog owners who want to reduce the risk of incurring costly medical bills for their pets would be well advised to choose nonpurebred dogs.

Which one of the following, if true, most seriously weakens the argument?

(A) Most genetically determined abnormalities in dogs do not seriously affect a dog’s general well-being.

(B) All dogs, whether purebred or nonpurebred, are subject to the same common nongenetically determined diseases.

(C) Purebred dogs tend to have shorter natural life spans than do nonpurebred dogs.

(D) The purchase price of nonpurebred dogs tends to be lower than the purchase price of purebred dogs.

(E) A dog that does not have genetically determined abnormalities may nevertheless have offspring with such abnormalities.

我选的是e,答案是d,我认为d是无关的。

13. Criticism that the press panders to public sentiment neglects to consider that the press is a profit-making institution. Like other private enterprises, it has to make money to survive. If press were not profit-making, who would support it? The only alternative is subsidy and, with it, outside control. It is easy to get subsidies for propaganda, but no one will subsidize honest journalism.

It can be properly inferred from the passage that if the pres is

(A) not subsidize, it is in no danger of outside control

(B) not subsidized, it will not produce propaganda

(C) not to be subsidized, it cannot be a profit-making institution

(D) to produce honest journalism, it must be profit-making institution

(E) to make a profit, it must produce honest journalism

这个题目我选d,答案是b

Lucien: Public-housing advocates claim that the many homeless people in this city are proof that there is insufficient housing available to them and therefore that more low-income apartment are needed. But that conclusion is absurd. Many apartments in my own building remain unrented and my professional colleagues report similar vacancies where they live. Since apartments clearly are available, homelessness is not a housing problem. Homelessness can, therefore, only be caused by people’s inability or unwillingness to work to pay the rent.

Maria: On the contrary, all recent studies show that a significant percentage of this city’s homeless people hold regular jobs. These are people who lack neither will nor ability.

14. Lucien’s argument against the public-housing advocates’ position is most vulnerable to which one of the following criticisms?

(A) It offers no justification for dismissing as absurd the housing advocates’ claim that there are many homeless people in the city

(B) It treats information acquired through informal conversations as though it provided evidence as strong as in information acquired on the basis of controlled scientific studies.

(C) It responds to a claim in which “available” is used in the sense of “affordable” by using “available” in the sense of “not occupied.”

(D) It overlooks the possibility that not all apartment buildings have vacant apartments for rent.

(E) It fails to address the issue, raised by the public-housing advocates’ argent, of who would pay for the construction of more low-income housing
当时这个题目我在c/e之间区分，后来觉得e说的更好，结果答案是c,e错在那里？？

17. Certain instruments used in veterinary surgery can be made either of stainless steel of nylon. In a study of such instruments, 10 complete sterilizations of a set of nylon instruments required 3.4 times the amount of energy used to manufacture that set of instruments, whereas 50 complete sterilizations of a set of stainless steel instruments required 2.1 time the amount of energy required to manufacture that set of instruments.

If the statements above are true, each of the following could be true EXCEPT:

(A) The 50 complete sterilizations of nylon instruments used more energy than did the 50 complete sterilizations of the stainless steel instruments.

(B) More energy was required for each complete sterilization of the nylon instruments than was required to manufacture the nylon instruments.

(C) More nylon instruments than stainless steel instruments were sterilized in the study.

(D) More energy was used to produce the stainless steel instruments than was used to produce the nylon instruments.

(E) The total cost of 50 complete sterilizations of the stainless steel instruments was greater than the cost of manufacturing the stainless steel instruments.
