GMAT CRITICAL REASONING REVIEW
1.Consumer Advocate: It is generally true, at least in this state, that lawyers who advertise a specific service charge less for that service lawyers who do not advertise. It is also true that {each time restrictions on the advertising of legal services have been eliminated, the number of lawyers advertising their services has increased and legal costs to consumers have declined in consequence.} However, eliminating the state requirement that legal advertisements must specify fees for specific services would almost certainly increase rather than further reduce consumers' legal costs. Lawyers would no longer have an incentive to lower their fees when they begin advertising and {if no longer required to specify fee arrangements, many lawyers who now advertise would increase their fees.}
In the consumer advocate's argument, the two portions in boldface{} play which of the following roles?

(A)The first is a generalization that the consumer advocate accepts as true; the secound is presented as a consequence that follows from the truth of that generalization.
(B)The first is a pattern of cause and effect that the consumoer advocate argues will be repeated in the case at issue; the second acknowledges a circumstance in which that pattern would not hold.
(C)The first is a pattern of cause and effect that the consumer advocate predicts will no hold in the case at issue; the second offers a consideration in support of that prediction.
(D)The first is evidence that the consumer advocate offers in support of a certain prediction; the second is that prediction.
(E)The first acknowledges a consideration that weighs against that main position that the consumer advocate defends; the second is that position.

2.Outsourcing is the practice of obtaining from an independent supplier a product of sercvice that a company has previously provided for itself. Since a company's chief objective is to realize the highest possilbe year-end profits, any product or service that can be obtained from an independent supplier for less than it would cost the company to provide the product or service on its own should be outsourced.

Which of the following, if ture, most seriously weakens the arguement?

(A)If a company decides to use independent suppliers for a product, it can generally exploit the vigorous competition arising among several firms that are interested in supplying that product.
(B)Successful outsourcing requires a company to provide its suppliers with information about its products and plans that can fall into the hands of its competitors and give them a business advantange,
(C)Certain tasks, such as processing a company's payroll, are commonly outsourced, whereas others, such as handling the company's core business, are not.
(D)For a company to provide a product or service for itself as efficiently as an independent supplier can provide it, the managers involved need to be as expert in the area of that product or service as the people in charge of that product or service at an independent supplier are.
(E)When a company decides to use an independent supplier for a product of service, the independent supplier sometimes hires members of the company's staff who formerly made the product or provided the service that the independent supplier now supplies.

3.A proposed change to ferderal income tax laws would eliminate deductions form taxable income for donations a taxpayer has made to charitable and educational institutions, If this change were adopted, wealthy individuals would no longer be permitted such deductions. Therefore, many charitable and educational institutions would have to reduce services, and some would have to close their doors.

The argument above assumes which of the following?

(A)Without the incentives offered by federal income tax laws, at least some wealthy individuals would not donate as much as money to charitable and educational institutions as they otherwise would have.
(B)Money contributed by individuals who make their donations because of provisions in the federal tax laws provides the only source of funding for many charitable and educational institutions.
(C)The primary reason for not adopting the proposed change in the federal income tax laws cited above is to protect wealthy individuals from having to pay higher taxes.
(D)Wealthy individuals who donate money to charitable and educational institutions are the only individuals who donate money to such institutions.
(E)Income tax laws should be changed to make donations to charitable and educational institutions the only permissable from taxable income.
