清月依云

1. In Kravonia, the average salary for jobs requiring a college degree has always been
higher than the average salary for jobs that do not require a degree. Current enrollments
in Kravonia’s colleges indicate that over the next four years the percentage of the
Kravonian workforce with college degrees will increase dramatically. Therefore, the
average salary for all workers in Kravonia is likely to increase over the next four years.

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

A. Kravonians with more than one college degree earn more, on average, than do Kravonians with only one college degree.
B. The percentage of Kravonians who attend college in order to earn higher salaries is higher now than it was several years ago.
C. The higher average salary for jobs requiring a college degree is not due largely to a scarcity among the Kravonian workforce of people with a college degree.
D. The average salary in Kravonia for jobs that do not require a college degree will not increase over the next four years.
E. Few members of the Kravonian workforce earned their degrees in other countries.
选C
我选了D
求解释啊~多谢！

c 的意思是因为scare, 导致 increased salary，题目说却说over the next four years the percentage of the Kravonian workforce with college degrees will increase dramatically，也就是说人多,不scare了,则salary不会increase.

去年北京的大蒜很贵，今年菜农都去种大蒜并且大丰收，所以今年菜农的收入会增加。
DA：去年大蒜贵不是因为资源稀缺。

题目说到“the average salary for all workers in Kravonia is likely to increase over the next four years”，c否定了由于稀缺性导致的工资上涨，从而与题目含义一致，即由学历拥有者人数多而导致，d提到无需学历的工作不会增长，没有明确提及其与工资上涨的关系
