You guys are right. C is correct.

Thanks! D is correct answer

Letter to the editor: After Baerton's factory closed, there was a sharp increase in the number of claims filed for job-related injury compensation by the factory's former employees. Hence there is reason to believe that most of those who filed for compensation after the factory closed were just out to gain benefits they did not deserve, and filed only to help them weather their job loss. Each of the following, if true, weakens the argument above EXCEPT: A. Workers cannot file for compensation for compensation for many job-related injuries, such as hearing loss from factory noise, until they have left the job. B. In the years before the factory closed, the factory's managers dismissed several employees who had filed injury claims. C. Most workers who receive an injury on the job file for compempensatoin on the day they suffer the injury. D. Workers who incur partial disabilities due to injuries on the job often do not file for compensatoin because they would have to stop working to receive compensatoin but cannot afford to live on that compensation alone. E. Workers who are aware that they will soon be laid off from a job often become depressed, making them more prone to job-related injuries.

Thanks, but A is not a answer

Ethicist: A society is just when, and only when, first, each person has an equal right to basic liberties, and second, inequalities in the distribution of income and wealth are not tolerated unless these inequalities are to everyone's advantage and are attached to jobs open to everyone. Which one of the following judgments most closely conforms to the principle described above? A. Society S guarrantees everyone an equal right to basic liberties, while allowing inequalities in the distribution of income and wealth that are to the advantage of everyone. Further, the jobs to which these inequalities are attached are open to most people. Thus, society S is just. B. Society S gives everyone an equal right to basic liberties, but at the expense of creating inequalities in the disstributioin of income and wealth. Thus, society S is not just. C. Society S allows inequalities in the distribution of income and wealth, although everyone benefits, and these inequalities are attached to jobs that are open to everyone. Thus, society S is just. D. Society S distributes income and wealth to everyone equally, but at the expense of creating inequalities in the right to basic liberties. Thus, society S is not just. E. Society S gives everyone an equal right to basic liberties, and although there is an inequality inthe distributoni of income and wealth, the jobs to which these inequalities are attached are open to all. Thus, society S is just.

Thanks a lot!!! GMAT-HELP

Yes, the correct answer is B. Can you explain this a little more? Thanks!

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. D. draws a conclusion about a specific belief based on responses to queries about two different specific beliefs E. contains premises that cannot all be true

ursula, thank you for your explanation. The correct answer is C.

In rescent years the climate has been gererally cool in northern Asia. But during periods when the average daily temperature and humidity in northern Asia were slightly higher than their normal levels the yields of most crops grown there increased significantly. In the next century, the increased average daily temperature and humidity attained during those periods are expected to become the norm. Yet scientists predict that the yearly yields of most of the region's crops will decrease during the next centruy. Which one of the following, if true, most helps to resolve the apparent paradox in the information above? A. Crop yields in southern Asia are expected to remain constant even after the average daily temperature and humidity there increase from recent levels. B. Any increases in temperature and humidity would be accompanied by higher levels of atmospheric carbon dioxide, which is vital to plant respiration. C. The climate in northern Asia has generally been too cool and dry in recent years for populations of many crop insect pests to become established. D. In many parts of Asia, the increased annual preciptation that would result form warmer and wetter climates would cause most edible plant species to flourish. E. The recent climate of northern Asia prevents many crops from being farmed there during the winter.

You are right! the correct answer is D

Biologist: Some speculate that the unusually high frequency of small goats found in island populations is a response to evolutionary pressure to increase the number of goats so as to ensure a diverse gene pool. However, only the reproductive success of a trait influences its frequency in a population. So, the only kind of evolutionary pressure that can reduce the average size of the members of a goat population is that resulting from small goats achieving greater reproductive success than their larger cousins. The biologist's view, if true, provides the most support for which one of the following? A. The evolutionary pressure to ensure a diverse gene pool could have the effect of increasing the frequency of a gene for small size. B. The unusual frequency of small goats in island populations is not a result of the greater reproductive success small goats possess when space is limited. C. Contrary to what some believe, large goats achieve greater reproductive success than small goates even when space is limited. D. The evolutionary pressure to ensure a diverse gene pool does not have the effect of increasing the frequency of a gene for small size. E. A diverse gene pool cnanot be achieved in a goat ppulation unless the average size of its members is reduced.

You are right! Thanks!

Smoking in bed has long been the main cause of home fires. Despite a significant decline in cigarette smoking in the last two decades, however, there has been no comparable decline in the number of people killed in home fires. Each one of the following statements, if true over the last trwo decades, helps to resolve the apparent discrepancy above EXCEPT: a. Compared to other types of home fires, home fires caused by somking in bed usually cause relatively little damage before they are extinguished. b. Home fires caused by smoking in bed often break out after the home's occupants have fallen asleep. c. Smokers who smoke in bed tend to be heavy smokers who are less likely to quit smoking than are smokers who do not smoke in bed. d. An increasing number of people have been killed in home fires that started in the kitchen. e. Population densities have increased, with the result that one home fire can cause more deaths than in previous decades.

Hi Ursula, You are so right! the correct answer is also 'A'. Thanks for your great explanation! Rob

Ursula, please help me, thanks! By contrast, other claim that technology subverts the artistic enterprise: that artistic efforts achieved with machines preempt human creativity, rather than being inspired by it. The originality of musical performance, for example, might suffer, as musicians would be deprived of the opportunity to spontaneously change pieces of music before live audiences. Some even worry that technology will eliminate live performance altogether; performances will e recorded for home viewing, abolishing the relationship between performer and audience. But these negative views assume both that technology poses an unprecedented challenge to the arts and that we are not committed enough to the artistic enterprise to preserve that live performance, assumptions that seem unnecessarily cynical. In fact, technology has traditionally assisted our capacity for creative expression and can refine our notions of any given art form. 1. it can be inferred from the passage that the author shared which one of the following opinions with the opponents of the use of new technology in art? a. the live performance is an important aspect of the artistic enterprise. b. the public's commitment to the artistic enterprise is questionable. c. recent technological innovations present as entirely new sort of challenge to art. d. technological innovations of the past have been very useful to artists. e. the performing arts are especially vulnerable to technological innovation.

ursula, you're right![clap]

A university should not be entitled to patent the inventions of its faculty members. Universities, as guarantors of intellectual freedom, should encourage the free flow of ideas and the general dissemination of knowledge. Yet a university that retains the right to patent the inventions of its faculty members has a motive to suppress information about a potentially valuable discouvery until the patent for it has been secured. Clearly, suppressing information concerning such discoveries is invompatible with the university's obligation to promote the free flow of ideas. Which one of the following is an assumption that the argument make? A. Universityies are the only institutions that have an obligation to guarantee intellectual freedom. B. Most inventions by university faculty members would be profitable if patented. C. Publication of reports on reseearch is the only practical way to disseminate information concerning new discoveries. D. Universities that have a motive to suppress information concerning discoveries by their faculty members will occasionally act on that motive. E. If the inventions of a university faculty member are not patented by that university, then they will be patented by the faculty member instead.

ursula, You are right, I'll change the topic next time. Thanks!

Hi ursula! I see. Thanks!!:)

Hi ursula! how about the following sentence? One would have to be blind to the reality of moral obligation to deny that people who believe a course of action to be morally obligatory for them have both the right and the duty to pursue that action, and that no one else has any right to stop them form doing so. Thanks! Rob

A lucid explanation! ursula, Thank you!

ursula, so 'and with it the magnetic field' is simply 'and with the pattern the magnetic field'. What does this sentence mean? does it mean 'with the pattern the magnetic field (is produced)'? or something else is missing in this sentence? Thanks!

ursula, How about the following sentence: "The reversal phenomenon may be triggered when something disturbs the heat circulation pattern of the outer core fluid, and with it the magnetic field." What's the referent of it here? Thanks!
