Even more worthwhile than this, however, is its role in expanding our knowledge and providing new, unexplored ideas. Kim: Your priorities are mistaken. Saving lives is what counts most of all. Without pure research, medicine would not be as advanced as it is. Laird and Kim disagree on whether pure researchDeselect Answer derives its significance in part from its providing new technologies expands the boundaries of our knowledge of medicine should have the saving of human lives as an important goal has its most valuable achievements in medical applications has any value apart from its role in providing new technologies to save lives None Q. 2 Executive: We recently ran a set of advertisements in the print version of a travel magazine and on that magazine’s website. We were unable to get any direct information about consumer response to the print ads. However, we found that consumer response to the ads on the website was much more limited than is typical for website ads. We concluded that consumer response to the print ads was probably below par as well. The executive’s reasoning does which one of the following?Deselect Answer bases a prediction of the intensity of a phenomenon on information about the intensity of that phenomenon’s cause uses information about the typical frequency of events of a general kind to draw a conclusion about the probability of a particular event of that kind infers a statistical generalization from claims about a large number of specific instances uses a case in which direct evidence is available to draw a conclusion about an analogous case in which direct evidence is unavailable bases a prediction about future events on facts about recent comparable events None Q. 3 During the construction of the Quebec Bridge in 1907, the bridge’s designer, Theodore Cooper, received word that the suspended span being built out from the bridge’s cantilever was deflecting downward by a fraction of an inch (2.54 centimeters). Before he could telegraph to freeze the project, the whole cantilever arm broke off and plunged, along with seven dozen workers, into the St. Lawrence River. It was the worst bridge construction disaster in history. As a direct result of the inquiry that followed, the engineering “rules of thumb” by which thousands of bridges had been built around the world went down with the Quebec Bridge. Twentieth-century bridge engineers would thereafter depend on far more rigorous applications of mathematical analysis. Which one of the following statements can be properly inferred from the passage?Deselect Answer Bridges built before about 1907 were built without thorough mathematical analysis and, therefore, were unsafe for the public to use. Cooper’s absence from the Quebec Bridge construction site resulted in the breaking off of the cantilever. Nineteenth-century bridge engineers relied on their rules of thumb because analytical methods were inadequate to solve their design problems Only a more rigorous application of mathematical analysis to the design of the Quebec Bridge could have prevented its collapse. Prior to 1907 the mathematical analysis incorporated in engineering rules of thumb was insufficient to completely assure the safety of bridges under construction None Q. 4 The supernova event of 1987 is interesting in that there is still no evidence of the neutron star that current theory says should have remained after a supernova of that size. This is in spite of the fact that many of the most sensitive instruments ever developed have searched for the tell-tale pulse of radiation that neutron stars emit. Thus, current theory is wrong in claiming that supernovas of a certain size always produce neutron stars. Which one of the following, if true, most strengthens the argument?Deselect Answer Most supernova remnants that astronomers have detected have a neutron star nearby. Sensitive astronomical instruments have detected neutron stars much farther away than the location of the 1987 supernova. The supernova of 1987 was the first that scientists were able to observe in progress. Several important features of the 1987 supernova are correctly predicted by the current theory. Some neutron stars are known to have come into existence by a cause other than a supernova explosion. None Q. 5 Political scientist: As a political system, democracy does not promote political freedom. There are historical examples of democracies that ultimately resulted in some of the most oppressive societies. Likewise, there have been enlightened despotisms and oligarchies that have provided a remarkable level of political freedom to their subjects. The reasoning in the political scientist’s argument is flawed because itDeselect Answer confuses the conditions necessary for political freedom with the conditions sufficient to bring it about fails to consider that a substantial increase in the level of political freedom might cause a society to become more democratic appeals to historical examples that are irrelevant to the causal claim being made overlooks the possibility that democracy promotes political freedom without being necessary or sufficient by itself to produce it bases its historical case on a personal point of view None Q. 6 Seven piano students—T, U, V, W, X, Y, and Z—are to give a recital, and their instructor is deciding the order in which they will perform. Each student will play exactly one piece, a piano solo. In deciding the order of performance, the instructor must observe the following restrictions: X cannot play first or second. W cannot play until X has played. Neither T nor Y can play seventh. Either Y or Z must play immediately after W plays. V must play either immediately after or immediately before U plays. If V plays first, which one of the following must be true? Deselect Answer T plays sixth. X plays third. Z plays seventh. T plays immediately after Y. W plays immediately after X.
