Questionsare based on the following passage.
As a society we might want to rethink the time and money spent on education, so that theseresources can benefit a greater percentage of the population．Ideally, both high schools and colleges canprepare individuals for the ever-changing roles that are likely to be expected of them.
High school degrees offer far less in the way of preparation for work than they might, or than manyother nations currently offer, creating a growing skills gap in our economy．We encourage students to goon to college whether they are prepared or not, or have a clear sense of purpose or interest, and nowhave the highest college dropout rate in the world.
We might look to other countries for models of how high schools can offer better training, as wellas the .development of a work ethic (勤奋工作的美德 ) and the intellectual skills needed for continuedlearning and development．I recommend Harvard's 2011 "Pathways to Prosperity" report for more~ attention to the "forgotten half" (those who do not go on to college) and ideas about how to addressthis issue.
Simultaneously, the liberal arts become, more important than ever．In a knowledge economy whereprofessional roles change rapidly and many college students are preparing for positions that may noteven exist yet, the sldll set needed is one that prepares them for change and continued learning.
Learning to express ideas well in both writing and speech, knowing how to find information, andknowing how to do research are all solid background skills for a wide variety of roles, and such trainingis more important than any particular major in a liberal arts college．We need to continue to valuebroad preparation in thinking skills that will serve for a lifetime.
Students also need to learn to work independently and to make responsible decisions．Thelengthening path to adulthood appears exacerbated (恶化) by parental involvement in the college years.
Given the rising investment in college education, parental concern is not surprising, but learning whereand when to intervene (干预 ) will help students take more ownership of the outcomes of theseincreasingly costly educations.
What kind of education does the author think is ideal? A．It benefits the great majority of the general population.
B．It prepares students to meet the future needs of society.
C．It encourages students to learn throughout their lives.
D．It ensures that students' expectations are successfully fulfilled.
