Start-up companies financed by venture capitalists have a much lower failure rate than companies financed by other means. Source of financing, therefore, must be a more important causative factor in the success of a start-up company than are such factors as the personal characteristics of the entrepreneur, the quality of strategic planning, or the management structure of the company.
Which of the following, if true, most seriously weakens the argument above?
(A) Venture capitalists tend to be more responsive than other sources of financing to changes in a start-up company's financial needs.
(B) The strategic planning of a start-up company is a less important factor in the long-term success of the company than are the personal characteristics of the entrepreneur.
(C) More than half of all new companies fail within five years.
(D) The management structures of start-up companies are generally less formal than the management structures of ongoing businesses.
(E) Venture capitalists base their decisions to fund start-up companies on such factors as the characteristics of the entrepreneur and quality of strategic planning of the company.

When people evade income taxes by not declaring taxable income, a vicious cycle results. Tax evasion forces lawmakers to raise income tax rates, which causes the tax burden on nonevading taxpayers to become heavier. This, in turn, encourages even more taxpayers to evade income taxes by hiding taxable income.
The vicious cycle described above could not result unless which of the following were true?
(A) An increase in tax rates tends to function as an incentive for taxpayers to try to increase their pretax incomes.
(B) Some methods for detecting tax evaders, and thus recovering some tax revenue lost through evasion, bring in more than they cost, but their success rate varies from year to year.
(C) When lawmakers establish income tax rates in order to generate a certain level of revenue, they do not allow adequately for revenue that will be lost through evasion.
(D) No one who routinely hides some taxable income can be induced by a lowering of tax rates to stop hiding such income unless fines for evaders are raised at the same time.
(E) Taxpayers do not differ from each other with respect to the rate of taxation that will cause them to evade taxes.

Because postage rates are rising, Home Decorator magazine plans to maximize its profits by reducing by one half the number of issues it publishes each year. The quality of articles, the number of articles published per year, and the subscription price will not change. Market research shows that neither subscribers nor advertisers will be lost if the magazine's plan is instituted.
Which of the following, if true, provides the strongest evidence that the magazine's profits are likely to decline if the plan is instituted?
(A) With the new postage rates, a typical issue under the proposed plan would cost about one-third more to mail than a typical current issue would.
(B) The majority of the magazine's subscribers are less concerned about a possible reduction in the quantity of the magazine's articles than about a possible loss of the current high quality of its articles.
(C) Many of the magazine's long-time subscribers would continue their subscriptions even if the subscription price were increased.
(D) Most of the advertisers that purchase advertising space in the magazine will continue to spend the same amount on advertising per issue as they have in the past.
(E) Production costs for the magazine are expected to remain stable.

When three Everett-owned Lightning-built airplanes crashed in the same month, the Everett company ordered three new Lightning-built airplanes as replacements. This decision surprised many in the airline industry because, ordinarily when a product is involved in accidents, users become reluctant to buy that product.
Which of the following, if true, provides the best indication that the Everett company's decision was logically well supported?
(A) Although during the previous year only one Lightning-built airplane crashed, competing manufacturers had a perfect safety record.
(B) The Lightning-built airplanes crashed due to pilot error, but because of the excellent quality of the planes there were many survivors.
(C) The Federal Aviation Association issued new guidelines for airlines in order to standardize safety requirements governing preflight inspections.
(D) Consumer advocates pressured two major airlines into purchasing safer airplanes so that the public would be safer while flying.
(E) Many Lightning Airplane Company employees had to be replaced because they found jobs with the competition.
