1)At present the Hollywood Restaurant has only standard-height tables. However, many customers come to watch the celebrities who frequent the Hollywood, and they would prefer tall tables with stools because such seating would afford a better view of the celebrities. Moreover, diners seated on stools typically do not stay as long as diners seated at standard-height tables. Therefore, if the Hollywood replaced some of its seating with high tables and stools, its profits would increase.
The argument is vulnerable to criticism on the grounds that it gives reason to believe that it is likely that
Ａ.some celebrities come to the Hollywood to be seen, and so might choose to sit at the tall tables if they were available
B. the price of meals ordered by celebrities dining at the Hollywood compensates for the longer time, if any, they spend lingering over their meals
C.a customer of the Hollywood who would choose to sit at a tall table would be an exception to the generalization about lingering
D.a restaurant's customers who spend less time at their meals typically order less expensive meals than those who remain at their meals longer
E.with enough tall tables to accommodate all the Hollywood's customers interested in such seating, there would be no view except of other tall tables
2) A year ago, Dietz Foods launched a yearlong advertising campaign for its canned tuna. Last year Dietz sold 12 million cans of tuna compared to the 10 million sold during the previous year, an increase directly attributable to new customers brought in by the campaign. Profits from the additional sales, however, were substantially less than the cost of the advertising campaign. Clearly, therefore, the campaign did nothing to further Dietz's economic interests.
Which of the following, if true, most seriously weakens the argument?
A . Sales of canned tuna account for a relatively small percentage of Dietz Foods' profits. .
B .Most of the people who bought Dietz's canned tuna for the first time as a result of the campaign were already loyal customers of other Dietz products. .
C .A less expensive advertising campaign would have brought in significantly fewer new customers for Dietz's canned tuna than did the campaign Dietz Foods launched last year. .
D .Dietz made money on sales of canned tuna last year. .
E .In each of the past five years, there was a steep, industry-wide decline in sales of canned tuna.
3) Bank depositors in the United States are all financially protected against bank failure because the government insures all individuals' bank deposits. An economist argues that this insurance is partly responsible for the high rate of bank failures, since it removes from depositors any financial incentive to find out whether the bank that holds their money is secure against failure. If depositors were more selective then banks would need to be secure in order to compete for depositors' money.
Which of the following, if true, most seriously weakens the economist s argument?
A. Before the government started to insure depositors against bank failure, there was a lower rate of bank failure than there is now.
B. When the government did not insure deposits frequent bank failures occurred as a result of depositors' fears of losing money in bank failures.
C. Surveys show that a significant proportion of depositors are aware that their deposits are insured by the government.
D. There is an upper limit on the amount of an individual's deposit that the government will insure. But very few individuals' deposits exceed this limit.
E. The security of a bank against failure depends on the percentage of its assets that are loaned out and also on how much risk its loans involve.
4) Guillemots are birds of Arctic regions. They feed on fish that gather beneath thin sheets of floating ice, and they nest on nearby land. Guillemots need 80 consecutive snow-free days in a year to raise their chicks, so until average temperatures in the Arctic began to rise recently, the guillemots' range was limited to the southernmost Arctic coast. Therefore, if the warming continues, the guillemots' range will probably be enlarged by being extended northward along the coast.
Which of the following, if true, most seriously weakens the argument?
A. Even if the warming trend continues, there will still be years in which guillemot chicks are killed by an unusually early snow.
B. If the Arctic warming continues, guillemots' current predators are likely to succeed in extending their own range farther north.
C. Guillemots nest in coastal areas, where temperatures are generally higher than in inland areas.
D. If the Arctic warming continues, much of the thin ice in the southern Arctic will disappear.
E. The fish that guillemots eat are currently preyed on by a wider variety of predators in the southernmost Arctic regions than they are farther north.
5)Travel agents are market intermediaries who make their living by gathering, organizing, and dispensing information about travel-related services that is not readily available to most consumers through new information technologies, such as the internet much of this information can now be made directly available to consumers demand for the services of travel agents will be drastically reduced.
Which of the following, if true, most seriously weakens the argument?
A. Travel agents routinely use the internet and other new information technologies as sources for the information they obtain for their customers.
B. The amount of information available through the internet and other new information technologies is increasing faster than the capabilities of most consumers to process it
C. Many people use travel-related services, such as airlines and hotels without consulting a travel agent .
D. The people who currently use the services of travel agents are also those most likely to gain access to new information technologies
E. The internet and other new information technologies are currently used by a relatively small proportion of the population
