3.The United States is not usually thought of as a nation of parakeet lovers. Yet in a census of parakeet owners in selected comparable countries, the United States ranked second, with eleven parakeet owners per hundred people. The conclusion can be drawn from this that people in the United States are more likely to own parakeets than are people in most other countries.

Knowledge of which of the following would be most useful in judging the accuracy of the conclusion? (A) The number of parakeets in the United States. (B) The number of parakeet owners in the United States. (C) The number of parakeet owners per hundred people in the country that ranked first in the census. (D) The number of parakeet owners in the United States compared to the numbers of owners of other pet birds in the United States. (E) The numbers of parakeet owners per hundred people in the countries not included in the census.

5.Stem borers are insect pests that often ruin North American corn crops. On some other continents, crop damage by stem borers is controlled by a certain species of wasp. Since these wasps cat nothing but stem borers, importing them into North America will keep crop damage from stem borers under control without endangering other North American insect species.

Which of the following is an assumption on which the argument depends? (A) Corn is the principal food of stem borers that live on continents other than North America. (B) The wasps are capable of surviving in North America long enough to eat significant numbers of stem borers. (C) No wasp in North America is closely related to the species of wasp that eats stem borers. (D) On continents other than North America, the wasps control stem borers more effectively than does any other pest control measure. (E) Corn crops on continents other than North America are not damaged by any insect pests other than stem borers.

7.Advertisement:

Of the many over-the-counter medications marketed for the relief of sinus headache, SineEase costs the least per dose. And SineEase is as effective per dose as the most effective of those other medications. So for relief from sinus headaches, SineEase is the best buy. Which of the following, if true, most seriously weakens the argument above? (A) Most of the over-the-counter medications marketed for the relief of sinus headache are equally effective per dose in providing such relief. (B) Many of the over-the-counter medications marketed for the relief of sinus headache contain the same active ingredient as SineEase. (C) People who suffer from frequent sinus headaches are strongly advised to consult a doctor before taking any over-the-counter medication. (D) An over-the-counter medication that is marketed for the relief of symptoms of head cold is identical in composition to SineEase but costs less per dose.

8.Crimes are mainly committed by the young, and for this reason merely increasing the number of police officers or expenditures on police services has little effect on reducing the crime rate. In fact, the only factor associated with a crimerate drop is a decrease in the number of People in the community aged fourteen to thirty.

(B) increasing prison terms for young people found guilty of crimes. (C) introducing compulsory military conscription for people aged seventeen to nineteen. (D) raising the age at which students are permitted to leave school. (E) a community's plan to increase the number of recreational and educational activities in which young adults can participate.

9.A member of the British Parliament is reputed to have said, "The First purpose of good social reform is to increase the sum total of human happiness.

10.The cost of the average computer logic device is falling at the rate of 25 percent per year, and the cost of the average computer memory device at the rate of 40 percent per year. It can be concluded that if these rates of cost decline remain constant for a period of three years, at the end of that time the cost of the average computer memory device will have declined by a greater amount than the Cost of the average computer logic device.

Accurate information about which of the following would be most useful in evaluating the correctness of the conclusion above? (A) The number of logic devices and memory devices projected to be purchased during the next three years. (B) The actual prices charged for the average computer logic device and the average computer memory device. (C) The compatibility of different manufacturers' logic devices and memory devices.

A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient. B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient. C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient. D. EACH statement ALONE is sufficient. E. Statements (1) and (2) TOGETHER are NOT sufficient.

14.Consumers in California seeking personal loans have fewer banks to turn to than do consumers elsewhere in the United States. This shortage of competition among banks explains why interest rates on personal loans in California are higher than in any other region of the United States.

Which of the following, if true, most substantially weakens the conclusion above? (A) Because of the comparatively high wages they must pay to attract qualified workers, California banks charge depositors more than banks elsewhere do for many of the services they offer. (B) Personal loans are riskier than other types of loans, such as home mortgage loans, that banks make.

(E) Interest rates paid by California banks to depositors are lower than those paid by banks in other parts of the United States because in California there is less competition to attract depositors.

16.Many geologists theorize that the trail of volcanic craters and cinder cones along the Snake River plain of southern Idaho was produced as the North American continent slid westward over a stationary "plume," a vertical channel through which molten rock rose intermittently from the Earth's core to burst through its crust.

Which of the following, if true, tends to support the geologists' theory of how the trail was produced? (A) The largest craters and cinder cones are on the eastern margin of the trail. (B) The most violent volcanic activity apparently occurred at the western margin of the trail. (C) The craters and cinder cones are evenly spaced throughout the extent of the trail.

(1)x+y=2x (2)x+y=0 (A) 条件(1)充分,但条件(2)不充分. (B) 条件(2)充分,但条件(1)不充分. (C) 条件(1)和(2)单独都不充分,但条件(1)和条件(2)联合起来充分. (D) 条件(1)充分,条件(2)也充分. (E) 条件(1)和条件(2)单独都不充分,条件(1)和条件(2)联合起来也不充分.

18.The senator has long held to the general printable that no true work of art is obscene and thus that there is no conflict between the need to encourage free artistic expression and the need to protect the sensibilities of the public from obscenity. When well-known works generally viewed as obscene are cited as possible counterexamples, the senator justifies accepting the principle by saying that if these works really are obscene then they cannot be works of art.

(C) It relies on an assertion of the senator authority. (D) It assumes what it seeks to establish. (E) It attempts to justify a position by appeal to an irrelevant consideration.

19.At the company picnic, all of the employees who participated in more than four of the scheduled events, and only those employees, were eligible for the raffle held at the end of the day. Since only a small proportion of the employees were eligibly for the raffle, most of the employees must have participated in fewer than four of the scheduled events.

Which one of the following arguments exhibits a flawed pattern of reasoning most like that exhibited by the argument above? (A) Only third-and fourth-year students are allowed to keep cars on campus. Since one quarter of the third-year students keep cars on campus and one half of the fourth-year students keep cars on campus, it must be that fewer third-year students than fourth-year students keep cars on campus. (B) Only those violin students who attended extra rehearsal sessions were eligible for selection as soloists. Since two of the violin students were selected as soloists, those two must have been the only violin students who attended the extra sessions.

Since ten of the club members are biology majors, those ten members must have volunteered at the hospital last summer. (E) All of the swim team members who had decreased their racing times during the season were given awards that no other members were given. Since fewer than half the team members were given such awards, the racing times of more than half the team members must have increased during the season.

20.Questions 10—11 are based on the following:

Antinuclear activist: The closing of the nuclear power plant is a victory for the antinuclear cause. It also represents a belated acknowledgment by the power industry that they cannot operate such plants safely. Nuclear power plant manager: It represents no such thing. The availability of cheap power from nonnuclear sources, together with the cost of mandated safety inspections and safety repairs, made continued operation uneconomic. Thus it was not safety considerations but economic considerations that dictated the plant's closing.

(D) Stress of many kinds has been shown to affect health adversely. (E) Adults who have never married have shorter life expectancies than do married people of the same age.

25.Many pregnant women suffer from vitamin deficiency, but this is frequently not due to vitamin deficiency in their diets; most often it is because they have higher requirements for vitamins than do the rest of the population.

The best criticism of the reasoning in the statement above is that it (A) fails to specify the percentage of pregnant women who suffer from vitamin deficiency. (B) gives insufficient information about why pregnant women have higher vitamin requirements than do other groups. (C) fails to employ the same reference group for both uses of the term "vitamin deficiency. " (D) provides insufficient information about the incidence of vitamin deficiency in other groups with high vitamin requirements. (E) uses "higher requirements" in an ambiguous manner.

26.A recent survey showed that 50 percent of people polled believe that elected officials should resign if indicted for a crime, whereas 35 percent believe that elected officials should resign only if they are convicted of a crime. Therefore, more people believe that elected officials should resign if indicted than believe that they should resign if convicted.

The reasoning above is flawed because it (A) draws a conclusion about the population in general based only on a sample of that population. (B) confuses a sufficient condition with a required condition. (C) is based on an ambiguity of one of its terms.

In response, the Sami delegation officially announced that it would definitely attend if both the Daquan and Kephrian delegations stayed away.

If the statements given are all true and all the delegations adhered to their official announcements, it must also be true that the (A) Daquan delegation attended the conference. (B) Daquan delegation did not attend the conference. (C) Sami government had no grievance against Tessia. (D) Tessian delegation did not attend the conference. (E) Tessian delegation made no official announcement regarding its attendance at the conference.

(A) Mr. Young is assigned the majority of the most difficult cases at the agency. (B) The other four bill collectors at the agency all consider Mr. Young to be a very capable bill collector. (C) Mr. Young's rate of collections per year has remained fairly steady in the last few years. (D) Before joining the agency, Mr. Young was affiliated with the credit department of a large department store.

33.If a mechanical aerator is installed in a fish pool, the water in the pool can be properly aerated. So, since John's fish pool does not have a mechanical aerator, it must be that his pool is not properly aerated. Without properly aerated water, fish cannot thrive. Therefore, any fish in John's pool will not thrive.

Which one of the following arguments contains an error of reasoning that is also contained in the argument above? (A) If alum is added to pickle brine, brine can replace the water in the pickles. Therefore, since Pauls does not add alum to her pickle brine, the water in the pickles cannot be replaced by brine. Unless their water is replaced with brine, pickles will not stay crisp. Thus, Paula's pickles will not stay crisp. (B) If pectin is added to jam, the jam will gel. Without a setting agent such as pectin, jam will not gel. So in order to make his jam gel, Harry should add a setting agent such as pectin to the jam. (C) If stored potatoes are not exposed to ethylene, the potatoes will not sprout. Beets do not release ethylene. Therefore, if Sara stores her potatoes together with beets, the potatoes will not sprout. (D) If a carrot patch is covered with mulch in the fall, the carrots can be left in the ground until spring. Without a mulch cover, carrots stored in the ground can suffer frost damage. Thus, since Kevin covers his carrot patch with mulch in the fall, the carrots can safely be left in the ground. (E) If tomatoes are not stored in a dark place, their seeds sometimes sprout. Sprouted seeds can make tomatoes inedible. Therefore, since Maria does not store her tomatoes in a dark place, some of Maria's tomatoes could be inedible.

35.Scientists have rediscovered certain food crops, once commonly cultivated in the New World, which contain more protein per pound than do current staple food crops such as rice and wheat. Scientists claim that cultivation of these crops could greatly benefit densely populated countries that have low per-person calorie intake and inadequate source of protein.

Which of the following, if true, casts the most serious doubt on the claim made above? (A) The average yield per acre of the rediscovered crops is substantially less than that of the current staple food crops. (B) Many important food crops, such as tomato, originated in the New World. (C) Wheat yields more protein per pound than does rice. (D) The rediscovered crops have more caloric per pound than do current, staple food crops. (E) As few as 20 different food crops provide the bulk of the planet's food supply.

36.False rumors of fiscal improprieties damage the reputation of a bank. If management does not attempt to refute these rumors, they will circulate and eventually destroy customer confidence.

(B) True rumors of fiscal improprieties do not do as much damage to customer confidence in a bank as false rumors do. (C) The best strategy for bank managers to adopt in the face of false rumors of fiscal improprieties is to address them directly. (D) Management cannot prevent already existing false rumors of fiscal improprieties from threatening a bank's reputation. (E) A bank's reputation for fiscal responsibility can be enhanced by favorable word of mouth.

37.Tom: Employers complain that people graduating from high school too often lack the vocational skills required for full-time employment. Therefore, since these skills are best acquired on the job, we should require high school students to work at part-time jobs so that they acquire the skills needed for today's job market.

Mary: There are already too few part-time jobs for students who want to work, and simply requiring students to work will not create jobs for them.

(B) It argues that Tom has mistaken an unavoidable trend for an avoidable one. (C) It provides information that is inconsistent with an explicitly stated premise in Tom's argument. (D) It presents a consideration that undercuts an assumption on which Tom's argument depends. (E) It defends an alternative solution to the problem that Tom describes.

40.Over the last century, paleontologists have used small differences between fossil specimens to classify Triceratops into sixteen species. This classification is unjustified, however, since the specimens used to distinguish eleven of the species come from animals that lived in the same area at the same time.

Which of the following, if true, would enable the conclusion of the argument to be properly drawn? (A) Not every species that lived in a given area is preserved as a fossil. (B) At least one individual of every true species of Triceratops has been discovered as a fossil specimen. (C) No geographical area ever supports more than three similar species at the same time. (D) In many species, individuals display quite marked variation. (E) Differences between fossil specimens of Triceratops that came from the same area are no less distinctive than differences between specimens that came from different areas.

(A) even only when n is even (B) even only when n is odd (C) odd whenever n is odd (D) divisible by 3 only when n is odd (E) divisible by 4 whenever n is even

42.John: I have tried several different types of psychotherapy at various times in my life: three kinds of "talk" therapy (Freudian, Rogerian, and cognitive) and also behavior therapy. Since the periods when I was in therapy were the least happy times of my life, I have concluded that psychotherapy cannot work for me.

Which of the following statements, if true, would most weaken John's conclusion? (A) Behavior therapy is designed to address different problems from those addressed by "talk" therapies. (B) The techniques used in behavior therapy are quite different from those used in "talk" therapies. (C) People who try several different types of psychotherapy tend to be happier than people who try only one type of psychotherapy.

(E) People undergoing psychotherapy that ultimately works are often unhappy while they are in therapy.

44.Politician: Pundits claim that by voting for candidates who promise to cut taxes, people show that they want the government to provide fewer services than it has been providing. By that reasoning, however, people who drink too much alcohol at a party in the evening want a headache the next morning.

Which of the following could replace the statement about people who drink too much without undermining the force of the politician's argument? (A) People who spend more money than they can afford want the things they spend that money on. (B) People who seek different jobs than they currently have do not want to work at all.

45.Why should the government, rather than industry or universities, provide the money to put a network of supercomputers in place? Because there is a range of problems that can be attacked only with the massive data-managing capacity of a supercomputer network. No business or university has the resources to purchase by itself enough machines for a whole network, and no business or university wants to invest in a part of a network if no mechanism exists for coordinating establishment of the network as a whole.

Which one of the following indicates a weakness in the argument? (A) It does not furnish a way in which the dilemma concerning the establishment of the network can be resolved. (B) It does not establish the impossibility of creating a supercomputer network as an international network. (C) It fails to address the question of who would maintain the network if the governments, rather than industry or universities provides the money for establishing it. (D) It takes for granted and without justification that it would enhance national preeminence in science for the government to provide the network. (E) It overlooks the possibility that businesses or universities, or both, could cooperate to build the network.

(E) The governor appointed two Black Americans, two Hispanic Americans, and one Asian American to high-level positions in his administration.

50.Since 1975 there has been in the United States a dramatic decline in the incidence of traditional childhood diseases such as measles. This decline has been accompanied by an increased incidence of Peterson's disease, a hitherto rare viral infection, among children. Few adults, however, have been affected by the disease.

Which of the following, if true, would best help to explain the increased incidence of Peterson's disease among children? (A) Hereditary factors determine in part the degree to which a person is susceptible to the virus that causes Peterson's disease. (B) The decrease in traditional childhood diseases and the accompanying increase in Peterson's disease have not been found in any other country. (C) Children who contract measles develop an immunity to the virus that causes Peterson's disease. (D) Persons who did not contract measles in childhood might contract measles in adulthood, in which case the consequences of the disease would generally be more severe. (E) Those who have contracted Peterson's disease are at increased risk of contracting chicken pox.
