in job safety training to lead to safer work environments.
Fact: A recent survey indicated, however, that for

manufacturers who improved job safety training during the

1980s, the number of on-the-job accidents tended to

Background Information: Hunters alone are blamed for the decline in Greenrock National Forest's deer population over the past ten years.  Yet clearly, black bears have also played an important role in this decline.
Fact:  In the past ten years, the forest's protected black bear population has risen sharply, and examination of black bears found dead in the forest during the deer hunting season showed that a number of them had recently fed on deer.

精简版：
Hunters thought that the rise of bear population also leads to the decline of deer population.

Background Information: Early in the twentieth century, Lake Konfa became very polluted.
Background Information:Recently fish populations have recovered as release of industrial pollutants has declined and the lake’s waters have become cleaner.
Premise:  Fears are now being voiced that the planned construction of an oil pipeline across the lake’s bottom might revive pollution and cause the fish population to decline again.  
Premise: However, a technology for preventing leaks is being installed.  
Conclusion: Therefore, provided this technology is effective, those fears are groundless.

Technology for preventing leaks can avoid the pollution thus the fears are groundless.

Industry experts expect improvements in job safety
training to lead to safer work environments. A recent
survey indicated, however, that for manufacturers
who improved job safety training during the 1980s,
the number of on-the-job accidents tended to
increase in the months immediately following the
changes in the training programs.

Safety training could improve the safety of the work environment (as measured by average number of accidents per worker, for example) while at the same time the number of total accidents could increase.
Which one of the following, if true, most helps to
resolve the apparent discrepancy in the passage
above?

A) A similar survey found that the number of on the-
job accidents remained constant after job
safety training in the transportation sector
was improved. 我没有意识到这是两个不同的部门

This answer choice will cast doubt on the survey in the argument, rather than reconcile the discrepancy.
(B) Manufacturers tend to improve their job safety
training only when they are increasing the
size of their workforce.

Yes, in this case, it points out the reason why on-the-job accidents tended to increase in the months immediately following the changes in the training programs. BA
(C) Manufacturers tend to improve job safety
training only after they have noticed that the
number of on-the-job accidents has
increased.

Actually, this answer choice reverses the sequence between these two.
(D) It is likely that the increase in the number of
on-the-job accidents experienced by many
companies was not merely a random
fluctuation.

This answer choice cannot resolve the contradiction.

This answer further confuses the issue. If the fluctuation was random, that could explain how an increase in accidents could follow safety training.
(E) Significant safety measures, such as protective
equipment and government safety
inspections, were in place well before the
improvements in job safety training.

It still cannot solve the discrepancy in the argument.

Fears are now being voiced that the planned construction of an oil pipeline across the lake’s bottom might revive pollution and cause the fish population to decline again. However, a technology for preventing leaks is being installed. Therefore, provided this technology is effective, those fears are groundless.
The argument depends on assuming which of the following?

A. Apart from development related to the pipeline, there will be no new industrial development around the lake that will create renewed pollution in its waters.

新的工业发展所带来的污染不属于这题讨论的范围，此题探讨的是石油管道的建设对于湖畔的影响！

New industrial development around the lake is outside the scope of the argument.
B. There is no reason to believe that the leak-preventing technology would be ineffective when installed in the pipeline in Lake Konfa.

Since the conclusion has revealed that “provided this technology is effective”, there is no need to assume that the technology would be ineffective.
C. The bottom of the lake does not contain toxic remnants of earlier pollution that will be stirred into the water by pipeline construction.

Yes, in this case, it refers to a question about the oil pipeline. BA
D. Damage to the lake’s fish populations would be the only harm that a leak of oil from the pipeline would cause.

Whether it is the only harm is irrelevant.
E. The species of fish that are present in Lake Konfa now are the same as those that were in the lake before it was affected by pollution.

The comparison is outside the scope of the argument.

Denoma, a major consumer-electronics maker, had a sizable decline in sales revenue for its most recent fiscal year. This result appears surprising, because electronics retailers report that although their overall sales were considerably lower than in the previous year, their sales revenue from Denoma models actually grew, largely thanks to some innovative and popular models that Denoma introduced.
Which of the following, if true, does most to explain the apparently surprising result?

A. Because of the need to educate the public about its new models’ capabilities, Denoma’s advertising spending was higher than normal over the period.

Its sales revenue should increase, rather decrease.
B. For the period at issue, Denoma’s major competitors reported declines in revenue that were, in percentage terms, greater than Denoma’s.

Denoma’s major competitors cannot tell the reason why Denoma’s sales revenue decreased.
C. A significant proportion of Denoma’s revenue comes from making components for other consumer-electronics manufacturers.

But how about the revenue, increase or decrease? We do not know.

虽然零售商那部分的销售收入增加了，但是如果这部分的收入减少，就能解释上面的矛盾了
D. Unlike some of its major competitors, Denoma has no lines of business outside consumer electronics to provide revenue when retail sales of consumer electronics are weak.

But retailers told that their sales revenue from Denoma models actually grew.
E. During the period, consumer-electronics retailers sold remaining units of Denoma’s superseded models at prices that were deeply discounted from those models’ original prices.

In this case, the discounted price reduced Denoma’s sales revenue. BA

虽然这一部分折扣产品的销售价格是下降的，但是零售商说他们来自于Denoma的总的收入上升了，所以不能很好解释问题里的矛盾！

Which of the following, if true, provides the best basis for a rebuttal of the criticism?

A. Even homeowners whose yards do not have water-conserving landscapes can conserve water by installing water-saving devices in their homes.

This answer choice cannot weaken the reason of the criticism, since it does not talk about the economic benefit.
B. A conventional landscape generally requires a much greater expenditure on fertilizer and herbicide than does a water-conserving landscape.

Yes, it weakens criticism’s reasoning. BA
C. A significant proportion of the residents of the city live in buildings that do not have yards.

Actually, this answer weakens the view of Brochure.
D. It costs no more to put in water-conserving landscaping than it does to put in conventional landscaping.

But it still cannot rebut the criticism. Which is more economic?
E. Some homeowners use more water to maintain their yards than they use for all other purposes combined.

Other purposes are outside the scope of the argument.
