Which one of the following is the main point of the passage as a whole?

(A) Because bald eagles symbolize freedom, conservation efforts should be concentrated on them rather than on other, more obscure species.

(B) The conservation of bald eagles is the first necessary step in conserving other endangered species.

(C) Without increased public sympathy for conservation, the needs of many symbolic species will go unmet.

(D) People’s love of the wilderness can be used to engender political support for conservation efforts.

(E) Other threatened species do not inspire people or foster sympathy as much as do bald eagles.

7. There is no reason why the work of scientists has to be officially confirmed before being published. There is a system in place for the confirmation or disconfirmation of scientific finding, namely, the replication of results by other scientists. Poor scientific work on the part of any one scientist, which can include anything from careless reporting practices to fraud, is not harmful. It will be exposed and rendered harmless when other scientists conduct the experiments and obtain disconfirmatory results.

Which one of the following, if true, would weaken the argument?

(A) Scientific experiments can go unchallenged for many years before they are replicated.

(B) Most scientists work in universities, where their work is submitted to peer review before publication.

(C) Most scientists are under pressure to make their work accessible to the scrutiny of replication.

(D) In scientific experiments, careless reporting is more common than fraud.

(E) Most scientists work as part of a team rather than alone.

8. Alice: Quotas on automobile imports to the United States should be eliminated. Then domestic producers would have to compete directly with Japanese manufacturers and would be forced to produce higher-quality cars. Such competition would be good for consumers.
