【正文】 ekers are able to fill the sorts of new jobs that have been created since 1992, and that these new positions are suitable for those jobseekers given their work experience, areas of interest, and former salaries. 144 ? as it stands the argument leaves open the possibility that the total number of donors decreased last year while the average amount given by each donor increased ? squander or misuse donated money 145 ? are statistically reliable ? Perhaps the study39。s subjects were unrepresentative of the overall population in terms of other traits and habits that might affect body weight. ? It is entirely possible that some other medical condition, or some other trait or habit, that causes snoring also causes weight gain. ? tend to gain weight as a result ? Thus the speaker should determine the cause of sleep apnea and modify the advice so that it targets that cause. ? would have considerable merit 146 ? would visit their school library more frequently and, in turn, would read more ? irst, the author unfairly assumes that since the number of library visits per student is declining the amount 9 of reading on the part of students must also be declining. ? It also ignores the possibility that more and more students are obtaining reading material elsewhere for example, from public libraries or from the Inter. ? a variety of other factors might account for the decline. As noted above, perhaps students are being less dependent on the school library for obtaining reading material and information. ? Perhaps increasing the number of puter terminals or the number of staff members would reverse the current trend. Or perhaps increasing the number of books and periodicals, or enhancing their variety, would be effective. ? these improvements alone would suffice. ? In fact, a more fortable library might actually discourage students from reading by creating a social rather than work atmosphere. 147 ? the author cannot rely on it to predict the success of Whirlwind39。s new games ? they are typical of videogame enthusiasts in that age group ? Yet it is entirely possible that the decline was due to factors such as imprudent pricing and distribution strategies or poor management, and that these problems have not been remedied. ? it was the agency39。s inability to attract interest among the key demographic group that caused the decline. Since the author has not dearly identified the cause of the decline ? Or perhaps Whirlwind39。s petitors are now introducing similar games at lower prices or with additional features that render them more attractive to videogame enthusiasts than Whirlwind39。s new games. Unless the author can rule out such possibilities, I simply cannot be swayed by the prediction that Whirlwind is about to experience a dramatic increase in sales. ? Perhaps videogame sales are highly seasonal and Whirlwind will need to wait longer than two months to see the dramatic increase it expects. If so, the author must modify the prediction accordingly. ? I would need to know (1) what caused the twoyear sales decline to begin with, and whether Whirlwind39。s new strategy eliminates that cause 148 ? The longer the time period between the collection of these statistics and the election, the greater the possibility that the tendency has changed over this time span, and the less justifiable the author39。s reliance on these statistics to support the claim that Monroetown residents oppose Brown39。s proposal. ? However, if the survey occurred long after the election, then the conflict can readily be explained by changing opinions and demographics over time. ? The national tendency 149 ? even though aircraft and auto mechanics serve similar functions, aircraft repair and maintenance is far more involved than car repair and maintenance ? However, it is entirely possible that their performance level is already very high and that the seminar will afford little or no improvement. Perhaps GetAway39。s mechanics have already attended a similar seminar, or perhaps they meet higher standards than the ones imposed on autoracing mechanics. ? However, it is possible that some other factor, such as improved diagnostic technology or more stringent inspection requirements, was the reason for the improved performance. ? Admittedly, if a low performance level results in accidents, customer satisfaction and profits will in all probability decrease. Otherwise, however, improved mechanic performance will in all likelihood have no bearing on customer satisfaction 10 ? show a strong causal nexus between improved mechanic performance and profit ? the cost of the seminar pared to its expected benefits 150 ? are not typical of the world in general ? provide data about amphibian population changes and pollution at diverse geographical locations 151 ? since the bridge is 20 years old it is unfair to assign blame for recent traffic problems and deterioration to Durant or to anyone else involved in the initial bridge building project. Given this time span it seems reasonable that these problems are due to ordinary wear and tear rather than to a design defect. ? For example, perhaps growth in the area39。s population, and therefore increased bridge traffic, has been greater than could have been anticipated 20 years ago. ? yet provides no evidence that the two bridges are similar in ways that are relevant to the argument. Even assuming weather conditions are generally the same at both locations, a variety of other factors might explain why the River Bridge problems have not occurred at the Derby Bridge. ? or perhaps the paratively long span of the Derby Bridge places less structural stress on any given point. ? It is quite possible, for example, that it was the only feasible plan, and that Durant had no choice. Moreover, mon sense tells me that deterioration and traffic problems are consequences of poo
