[单选题]Skeptics of higher education often complain that universities offer too many boring degrees with little value in the workplace. 1______elite universities tend to produce higher-earning graduates than less selective institutions do, you might 2______them to teach more practical courses. 3______data from Britain’s Department for Education show the opposite. Undergraduate students at 4______universities are more likely to study purely academic 5______such as philosophy and classics, whereas those at less choosy ones tend to 6______vocational topics such as business or nursing. What could 7______this seeming contradiction? One reason is that employers treat a 8______from a top university as an indicator for intelligence. This means that students at elite institutions can study bookish subjects and still succeed 9______. The median Cambridge graduate in a creative-arts subject—the university’s least profitable group of courses, including fields such as music—earns around ?25,000 ($32,400) at age 26. Economics students from less elite universities, such as Hull, make a similar 10______. Yet even though Oxbridge students can pretend to read "Ulysses" for years and still expect a 11______salary, they end 12______paying a large opportunity cost by pursuing the arts. That is because employers reserve the highest starting wages for students who both attended a leading university and also 13______a marketable subject. Many gifted arts students would struggle to deal with numbers. But for those who can excel at both, the cost of sticking with the arts is 14______. Cambridge creative-arts students have A-level scores close to those of economics students at Warwick, but 15______about half as much. Who can 16______such indulgence? The answer is Oxbridge students, who often have rich parents. At most universities, students in courses that 17______high-paying jobs, such as economics and medicine, tend to come from wealthier families, partly because such 18______are more likely to have the examination scores necessary to be accepted. At Oxbridge, 19______, no such association exists. History and philosophy students there come from richer parts of Britain, on average, than their 20______studying medicine do. 第1题答案是______。
