The passage mostly agree that Heney’s findings about temperature in the San Andreas Fault made the greatest contribution in that they      

1. revealed an error in previous measurements of temperature in the San Andreas Fault zone
2. indicated the types of clay present in the rocks that form the San Andreas Fault
3. established the superiority of a particular technique for evaluating data concerning friction in the San Andreas Fault
4. suggested that geologists had inaccurately assumed that giant rock plates that meet at the San Andreas Fault generate heat through friction
5. confirmed geologists’ assumptions about the amount of friction generated by common varieties of rocks, such as limestone and granite

细节题

本题分析：

本题是问文章中指出H的发现有什么重大作用？

选项A中的measurements是复数形式，但文中并未提到H发现前的多次测量，因此错误。 选项B错，作者并未表明其所属内容。

选项C错误，作者近罗列了一些对这一发现的解释，最后并未对某种解释做出定论。 选项E的错误同选项C的一样。

文章第一段说明H的发现与之前科学家估计的不同，说明其之前的科学家估计的是错误的。因此答案是D.

The average hourly wage of television assemblers in Vernland has long been significantly lower than that in neighboring Borodia.  Since Borodia dropped all tariffs on Vernlandian televisions three years ago, the number of televisions sold annually in Borodia has not changed.  However, recent statistics show a droip in the number of television assemblers in Borodia.  Therefore, updated trade statistics will probably indicate that the number of televisions Borodia imports annually from Vernland has increased.

Which of the following is an assumption on which the argument depends?

1. The number of television assemblers in Vernland has increased by at least as much as the number of television assemblers in Borodia has decreased.
2. Televisions assembled in Vernland have features that televisions assembled in Borodia do not have.
3. The average number of hours it takes a Borodian television assembler to assemble a television has not decreased significantly during the past three years.
4. The number of televisions assembled annually in Vernland has increased significantly during the past three years.
5. The difference between the hourly wage of television assemblers in Vernland and the hourly wage of television assemblers in Borodia is likely to decrease in the next few years.

前提是：V的电视装配工人的工资比B的低，B3年前解除了与V的贸易禁令，且B本国的电视机销售产量不变。然而近期数据表明B国的电视装配员工数有下降。

结论：B从V进口的电视及数量增加

选项A中装配工人人数题目中未提过，无关词；B超出题目范围；D虽然说明V电视装配量增加，但未指出其增加的量都销往V，所以不对；E超出题目范围

正确的为C:装配数量=装配工人数*每人的装配效率(即每人每小时装配数量)-->装配小时率未变化，而装配员工数减少，则说明B的电视组装总数减少，因此有力证明其不变的电视销量中有从V进口的

The city of Workney, in raising bus fares from $1.00 to $1.25, proposed that 18 fare tokens be sold for $20.00 to alleviate the extra burden of the fare increase on the city’s low-income residents.  Critics suggested alternatively that 9 fare tokens be sold for $10.00, because a $20.00 outlay would be prohibitive for low-income riders.

The alternative proposal depends on which of the following assumptions?

1. Low-income residents of Workney will continue to ride the buses in the same numbers despite the fare increase.
2. Low-income riders would be more likely to take advantage of the savings afforded by the 9-token offer than would other riders.
3. The outlay of $10.00 for the purchase of 9 fare tokens would not be prohibitive for low-income bus riders.
4. The proposed fare increase is needed for the purchase of new buses for the city’s bus system.
5. Buses provide the only means of public transportation in the city of Workney.

前提：为了将公交车费由1元提高到1.25元，城市W提议将18块钱的代价券卖20元以减少低收入家庭乘车难的问题。
结论建议：批评家指出应将9元钱的代价券卖10元，因为低收入家庭支付不起20元的费用。
正确的假设是支持批评家的建议，那么可推出9元的代价券是在低收入家庭可支付的范围内的，因此选C

Tanco, a leather manufacturer, uses large quantities of common salt to preserve animal hides.  New environmental regulations have significantly increased the cost of disposing of salt water that results from this use, and, in consequence, Tanco is considering a plan to use potassium chloride in place of common salt.  Research has shown that Tanco could reprocess the by-product of potassium chloride use to yield a crop fertilizer, leaving a relatively small volume of waste for disposal.

In determining the impact on company profits of using potassium chloride in place of common salt, it would be important for Tanco to research all of the following EXCEPT:

1. What difference, if any, is there between the cost of the common salt needed to preserve a given quantity of animal hides and the cost of the potassium chloride needed to preserve the same quantity of hides?
2. To what extent is the equipment involved in preserving animal hides using common salt suitable for preserving animal hides using potassium chloride?
3. What environmental regulations, if any, constrain the disposal of the waste generated in reprocessing the by-product of potassium chloride?
4. How closely does leather that results when common salt is used to preserve hides resemble that which results when potassium chloride is used?
5. Are the chemical properties that make potassium chloride an effective means for preserving animal hides the same as those that make common salt an effective means for doing so?

Which of the following most logically completes the argument?

Yorco and Zortech are two corporations that employ large numbers of full-time workers who are paid by the hour.  Publicly available records indicate that Yorco employs roughly the same number of such hourly wage workers as Zortech does but spends a far higher total sum per year on wages for such workers.  Therefore, hourly wages must be higher, on average, at Yorco than at Zortech, since _____.

1. Zortech spends a higher total sum per year than Yorco does to provide its hourly wage workers with benefits other than wages
2. the work performed by hourly wage workers at Zortech does not require a significantly higher level of skill than the work performed by hourly wage workers at Yorco does
3. the proportion of all company employees who are hourly wage workers is significantly greater at Yorco than it is at Zortech
4. overtime work, which is paid at a substantially higher rate than work done during the regular work week, is rare at both Yorco and Zortech
5. the highest hourly wages paid at Yorco are higher than the highest hourly wages paid at Zortech

Environmental organizations want to preserve the land surrounding the Wilgrinn Wilderness Area from residential development.  They plan to do this by purchasing that land from the farmers who own it.  That plan is ill-conceived:  if the farmers did sell their land, they would sell it to the highest bidder, and developers would outbid any other bidders.  On the other hand, these farmers will never actually sell any of the land, provided that farming it remains viable.  But farming will not remain viable if the farms are left unmodernized, and most of the farmers lack the financial resources modernization requires.  And that is exactly why a more sensible preservation strategy would be to assist the farmers to modernize their farms to the extent needed to maintain viability.

In the argument as a whole, the two boldface proportions play which of the following roles?

1. The first presents a goal that the argument concludes cannot be attained; the second is a reason offered in support of that conclusion.
2. The first presents a goal that the argument concludes can be attained; the second is a judgment disputing that conclusion.
3. The first presents a goal, strategies for achieving which are being evaluated in the argument; the second is a judgment providing a basis for the argument’s advocacy of a particular strategy.
4. The first presents a goal that the argument endorses; the second presents a situation that the argument contends must be changed if that goal is to be met in the foreseeable future.
