Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 28 to 34.

After  twenty  years  of  growing  student  enrollments  and  economic prosperity,  business  schools  in the United States have started to face harder times. Only Harvard’s MBA School has shown a substantial increase  in  enrollment  in  recent  years.  Both  Princeton  and  Stanford  have  seen  decreases  in  their enrollments.  Since  1990,  the  number  of  people  receiving  Masters  in  Business  Administration (MBA) degrees,  has  dropped  about  3  percent  to  75,000,  and  the  trend  of  lower  enrollment  rates  is  expected  to continue.
There are two factors causing this decrease in students seeking an MBA degree. The first one is that many graduates of four-year colleges are finding that an MBA degree does not guarantee a plush job on Wall Street, or in other financial districts of major American cities. Many of the entry- level management jobs are going to students graduating with Master of Arts degrees in English and the humanities as well as those holding MBA degrees. Students have asked the question, “Is an MBA degree really what I need to be  best  prepared  for  getting  a  good  job?”  The  second  major  factor  has  been  the  cutting  of  American payrolls and the lower number of entry-level jobs being offered. Business needs are changing, and MBA schools are struggling to meet the new demands.
