1) Professor Chan: The literature department’s undergraduate courses should cover only true literary works, and not such frivolous material as advertisements.
Professor Wigmore: Advertisements might or might not be true literary works but they do have a powerfully detrimental effect on society—largely because people cannot discern their real messages. The literature department’s courses give students the critical skills to analyze and understand texts. Therefore, it is the literature department’s responsibility to include the study of advertisements in its undergraduate courses.

Which one of the following principles most strongly supports Professor Wigmore’s argument?
(A) Advertisements ought to be framed in such a way that their real messages are immediately clear.
(B) Any text that is subtly constructed and capable of affecting people’s thought and action ought to be considered a form of literature.
(C) All undergraduate students ought to take at least one course that focuses on the development of critical skills.
(D) The literature department’s courses ought to enable students to analyze and understand any text that could have a harmful effect on society.
(E) Any professor teaching an undergraduate course in the literature department ought to be free to choose the material to be covered in that course.

D) says whatever text which could have a detrimental effect on society should be part of the literature department's course. This principle supports the conclusion of Prof. W., who maintains that it is the literature department’s responsibility to include the study of advertisements, which is not a true form of literature.

2) Ethicist: In a recent judicial decision, a contractor was ordered to make restitution to a company because of a bungled construction job, even though the company had signed a written agreement prior to entering into the contract that the contractor would not be financially liable should the task not be adequately performed. Thus, it was morally wrong for the company to change its mind and seek restitution.

Which one of the following principles, if valid, most helps to justify the ethicist’s reasoning?
(A) It is morally wrong for one party not to abide by its part of an agreement only if the other party abides by its part of the agreement.
(B) It is morally wrong to seek a penalty for an action for which the agent is unable to make restitution.
(C) It is morally wrong for one person to seek to penalize another person for an action that the first person induced the other person to perform.
(D) It is morally wrong to ignore the terms of an agreement that was freely undertaken only if there is clear evidence that the agreement was legally permissible.
(E) It is morally wrong to seek compensation for an action performed in the context of a promise to forgo such compensation.

E) says it is wrong to charge a fee which is originial said not to be charged in a promise or agreement. This is in line with the point of view of the auther, who maintains that  it was morally wrong for the company to change its mind and seek restitution.


3) The government-owned gas company has begun selling stoves and other gas appliances to create a larger market for its gas. Merchants who sell such products complain that the competition will hurt their businesses. That may well be; however, the government-owned gas company is within its rights. After all, the owner of a private gas company might will decide to sell such appliances and surely there would be nothing wrong with that.

Which one of the following principles, if valid, most helps justify the reasoning above?
(A) Government-owned companies have the right to do whatever private businesses have the right to do.
(B) A government should always take seriously the complaints of merchants.
(C) Private businesses have not right to compete with government monopolies.
(D) There is nothing wrong with a government-owned company selling products so long as owners of private companies do not complain.
(E) There is nothing wrong with private companies competing against each other.

Here we have the standard structure: "however, main conclusion." So the conclusion is that the government-owned gas company is within its rights to sell stoves and other gas appliances. If choice A) is true, then the conclusion of the passage is true as well.


4) Walter: Although cigarette smoking is legal, it should be banned on all airline flights. Cigarette smoking in the confines of an aircraft exposes nonsmokers to harmful secondhand smoke that they cannot avoid.

Which one the following principles, if established, would justify the proposal put forth by Walter?
(A) People should be prohibited from engaging in an otherwise legal activity would unavoidable expose others to harm.
(B) An activity should be banned only if most situations in which a person engaged in that activity would inevitably expose others to harm.
(C) A legal activity that has the potential for causing harm to others in certain situations should be modified in those situations to render it harmless.
(D) People who regularly engage in an activity that has the potential for harming others when that activity takes place in certain situations should be excluded from those situations.
(E) If an activity is legal in some situations in which a person’s engaging in that activity could harm others, then that activity should be legal in all situations.

Here again, we the standard structure of "Although, main conclusion." So the main conclusion is: Smoking should be banned on all airline flights. The reason for that is that smoking within an airplane cabin would hurt passengers who do not want to smoke. A) provides a foundation to support the author's opinion.


5) New legislation would require a seven-day waiting period in the sale of handguns to private individuals, in order that records of prisons could be checked and the sale of handguns to people likely to hurt other people thereby prevented. People opposed to this legislation claim that prison records are so full of errors that the proposed law would prevent as many law-abiding citizens as criminals from having access to handguns.

If the claim made by people opposed to the new legislation is true, which one of the following is a principle that, if established, would do the most to justify opposition to the new legislation on the basis of that claim?
(A) The rights of law-abiding citizens are more worthy of protection than are the rights of criminals.
(B) Nothing should be done to restrict potential criminals at the cost of placing restrictions on law-abiding citizens.
(C) Legislation should not be enacted if no benefit could accrue to society as a
(D) No restrictions should be placed on the sale of merchandise unless sale of that merchandise could endanger innocent people.
(E) Even citizens who are neither fugitives nor felons should not be permitted to own a handgun unless they have received adequate training.

B), obviously would help those who oppose the 7-day waiting period regulation to reach their conclusion. So B) is the answer.

第4题 why not C?

Reading comprehension.

The conclusion of the passage is to BAN an otherwise legal activity, not to MODIFY the same activity and MAKE it harmless. Asking people to smoke "healthy and harmless" cigarettes would be what answer choice C) asks for.

第4题 why not C?

Yes. Some principle questions are like strengthen questions.

can you elaborate on Q1 please?

Why B is incorrect?
Also, I eliminated D because of " a harmful effect" which I think comes out of nowhere...
Thanks!
