涛涛2-Q17,Q18,Q19

涛涛2-Q17:

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?

Q18:

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

为什么选D?Y和Z的小时工资和人数都相等,总工资怎么回比Z高呢?

Q19:

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 rejects as ill-conceived; the second is evidence that is presented as grounds for that rejection.
  2. The first presents a goal that the argument concludes cannot be attained; the second is a reason offered in support of that conclusion.
  3. The first presents a goal that the argument concludes can be attained; the second is a judgment disputing that conclusion.
  4. 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.
  5. 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.

为什么选D不选A,B?
