Logical Reasoning MCQ Set 14

Question : A conservation group in the United States is trying to change the long-standing image of bats as frightening creatures. The group contends that bats are feared and persecuted solely because they are shy animals that are active only at night.
Which of the following, if true, would cast the most serious doubt on the accuracy of the group's contention?

1. Bats are steadily losing natural roosting places such as caves and hollow trees and are thus turning to more developed areas for roosting.
2. Bats are the chief consumers of nocturnal insects and thus can help make their hunting territory more pleasant for humans.
3. Bats are regarded as frightening creatures not only in the United States but also in Europe, Africa, and South America.
4. Raccoons and owls are shy and active only at night; yet they are not generally feared and persecuted.
5. People know more about the behavior of other greatly feared animal species, such as lions, alligators, and snakes, than they do about the behavior of bats.

Question : Meteorite explosions in the Earth's atmosphere as large as the one that destroyed forests in Siberia, with approximately the force of a twelve-megaton nuclear blast, occur about once a century. The response of highly automated systems controlled by complex computer programs to unexpected circumstances is unpredictable.
Which of the following conclusions can most properly be drawn, if the statements above are true, about a highly automated nuclear-missile defense system controlled by a complex computer program?

1. Within a century after its construction, the system would react inappropriately and might accidentally start a nuclear war.
2. The system would be destroyed if an explosion of a large meteorite occurred in the Earth's atmosphere.
3. It would be impossible for the system to distinguish the explosion of a large meteorite from the explosion of a nuclear weapon.
4. Whether the system would respond inappropriately to the explosion of a large meteorite would depend on the location of the blast.
5. It is not certain what the system's response to the explosion of a large meteorite would be, if its designers did not plan for such a contingency.

Question : Defense Department analysts worry that the ability of the United States to wage a prolonged war would be seriously endangered if the machine-tool manufacturing base shrinks further. Before the Defense Department publicly connected this security issue with the import quota issue, however, the machine-tool industry raised the national security issue in its petition for import quotas.
Which of the following, if true, contributes most to an explanation of the machine-tool industry's raising the issue above regarding national security?

1. When the aircraft industries retooled, they provided a large amount of work for tool builders.
2. The Defense Department is only marginally concerned with the effects of foreign competition on the machine-tool industry.
3. The machine-tool industry encountered difficulty in obtaining governmental protection against imports on grounds other than defense.
4. A few weapons important for defense consist of parts that do not require extensive machining.
5. Several federal government programs have been designed which will enable domestic machine-tool manufacturing firms to compete successfully with foreign toolmakers.

he fewer restrictions there are on the advertising of legal services, the more lawyers there are who advertise their services, and the lawyers who advertise a specific service usually charge less for that service than lawyers who do not advertise. Therefore, if the state removes any of its current restrictions, such as the one against advertisements that do not specify fee arrangements, overall consumer legal costs will be lower than if the state retains its current restrictions.

Question1 : If the statements above are true, which of the following must be true?

1. Some lawyers who now advertise will charge more for specific services if they do not have to specify fee arrangements in the advertisements.
2. More consumers will use legal services if there are fewer restrictions on the advertising of legal services.
3. If the restriction against advertisements that do not specify fee arrangements is removed, more lawyers will advertise their services.
4. If more lawyers advertise lower prices for specific services, some lawyers who do not advertise will also charge less than they currently charge for those services.
5. If the only restrictions on the advertising of legal services were those that apply to every type of advertising, most lawyers would advertise their services

Question2 : Which of the following, if true, would most seriously weaken the argument concerning overall consumer legal costs?

1. The state has recently removed some other restrictions that had limited the advertising of legal services.
2. The state is unlikely to remove all of the restrictions that apply solely to the advertising of legal services.
3. Lawyers who do not advertise generally provide legal services of the same quality as those provided by lawyers who do advertise.
4. Most lawyers who now specify fee arrangements in their advertisements would continue to do so even if the specification were not required.
5. Most lawyers who advertise specific services do not lower their fees for those services when they begin to advertise.

Question : Opponents of laws that require automobile drivers and passengers to wear seat belts argue that in a free society people have the right to take risks as long as the people do not harm others as a result of taking the risks. As a result, they conclude that it should be each person's decision whether or not to wear a seat belt.
Which of the following, if true, most seriously weakens the conclusion drawn above?

1. Many new cars are built with seat belts that automatically fasten when someone sits in the front seat.
2. Automobile insurance rates for all automobile owners are higher because of the need to pay for the increased injuries or deaths of people not wearing seat belts.
3. Passengers in airplanes are required to wear seat belts during takeoffs and landings.
4. The rate of automobile fatalities in states that do not have mandatory seat-belt laws is greater than the rate of fatalities in states that do have such laws.
5. In automobile accidents, a greater number of passengers who do not wear seat belts are injured than are passengers who do wear seat belts.

Question : The cost of producing radios in Country Q is ten percent less than the cost of producing radios in Country Y. Even after transportation fees and tariff charges are added, it is still cheaper for a company to import radios from Country Q to Country Y than to produce radios in Country Y.

1. Labor costs in Country Q are ten percent below those in Country Y.
2. Importing radios from Country Q to Country Y will eliminate ten percent of the manufacturing jobs in Country Y.
3. The tariff on a radio imported from Country Q to Country Y is less than ten percent of the cost of manufacturing the radio in Country Y.
4. The fee for transporting a radio from Country Q to Country Y is more than ten percent of the cost of manufacturing the radio in Country Q.
5. It takes ten percent less time to manufacture a radio in Country Q than it does in Country Y.
