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 _____.

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

GWD-03 Q2

Q2:

Kernland imposes a high tariff on the export of unprocessed cashew nuts in order to ensure that the nuts are sold to domestic processing plants.  If the tariff were lifted and unprocessed cashews were sold at world market prices, more farmers could profit by growing cashews.  However, since all the processing plants are in urban areas, removing the tariff would seriously hamper the government's effort to reduce urban unemployment over the next five years.

Which of the following, if true, most seriously weakens the argument?

1. Some of the by-products of processing cashews are used for manufacturing paints and plastics.
           
2. Other countries in which cashews are processed subsidize their processing plants.
           
3. More people in Kernland are engaged in farming cashews than in processing them.
           
4. Buying unprocessed cashews at lower than world market prices enables cashew processors in Kernland to sell processed nuts at competitive prices.
                   
5. A lack of profitable crops is driving an increasing number of small farmers in Kernland off their land and into the cities.
           

   Answer: E

答案为E, 但是increasing farmers moving into city 应该会加剧unemployment in urban areas才对呀？
