. Modern navigation systems, which are found in most of today's commercial aircraft, are made with low-power circuitry, which is more susceptible to interference than the vacuum-tube circuitry found in older planes. During landing, navigation systems receive radio signals from the airport to guide the plane to the runway.
Recently, one plane with low-power circuitry veered off course during landing, its dials dimming, when a passenger turned on a laptop computer. Clearly, modern aircraft navigation systems are being put at risk by the electronic devices that passengers carry on board, such as cassette players and laptop computers.

The two portions in boldface play which of the following roles?

(A) The first is a principle that the argument relies on and the second is a conclusion that can be drawn from the first.
(B) The first is a fact that argument relies on and the second is a conclusion that must be drawn from this argument.
(C) The first acknowledges a consideration that supports that main position; the second is that conclusion.
(D) The first is an evidence that supports the conclusion, the second is that conclusion.
(E) The first is a principle that is necessary for this argument, the second is a conclusion that could be drawn from this argument.
求教b和e选项的前半部分是不是都对？以及b的后半部分的must是不是不对？是不是这种题一看是must就可以直接排除呢？

8) Psychology professor: The percentage of children having psychological problems is higher among children of Sea Turtle parents than among other children in China. However, it would be wrong to conclude that these psychological problems are caused by the difficulty these expatriates’ children have adjusting to a new environment in China. It is just as rational to infer that certain behaviors which accompany the Sea Turtle families before the move —anxiety for and uncertainties of their future—are learned by children from their Sea Turtle parents, and that it is these learned behaviors, rather than the difficulty of adjusting to lives in China, that cause the children’s psychological problems.

What role does the assertion that children of Sea Turtle parents have a higher rate of psychological problems than other children in China play in the argument above?

(A) It is the final conclusion of the argument.
(B) It is an established claim that the argument tries to refute.
(C) It is offered as evidence for the claim that going back to China is harmful to the children of the Sea Turtle parents.
(D) It is offered as evidence for the claim that certain behaviors are often responsible for expatriates and their children.
(E) It is cited as an established finding for which the argument proposes a reasonable explanation.
for this question, why B is not right?

role
1)main conclusion
2)premise/opposing opinion/concession
3)structure

the answer
1)focus on the effective phrases
2)make the abstract answer into concrete meaning
  eg.the answer:the only conclusion
     the passage has both the main conclusion and the intermediate conclusion
conclusion and  inference
conclusion is the statement reached by the facts and statistics
whilst the inference is the possible consequence of the conclusion,which is the objective opinion
based on the objective conclusions

5) Aroca City currently funds its public schools through taxes on property. In place of this system, the city plans to introduce a sales tax of three percent on all retail sales in the city. Critics protest that three percent of current retail sales falls short of the amount raised for schools by property taxes. The critics are correct on this point. Nevertheless, implementing the plan will probably not reduce the money going to Aroca's schools. Several large retailers have selected Aroca City as the site for huge new stores, and these are certain to draw large numbers of shoppers from neighboring municipalities, where sales are taxed at rates of six percent and more. In consequence, retail sales in Aroca City are bound to increase substantially.

In the argument given, the two potions in boldface play which of the following roles?

A. The first is an objection that has been raised against a certain plan; the second is a prediction that, if accurate, undermines the force of that objection.
B. The first is a criticism, endorsed by the argument, of a funding plan; the second is a point the argument makes in favor of adopting an alternative plan.
C. The first is a criticism, endorsed by the argument, of a funding plan; the second is the main reason cited by the argument for its endorsement of the criticism.
D. The first is a claim that the argument seeks to refute; the second is the main point used by the argument to show that the claim is false.
E. The first is a claim that the argument accepts with certain reservations; the second presents that claim in a rewarding that is not subject to those reservations.
