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:

In my experience, freshmen today are different from those I knew when I started as a counselor and professor 25 years ago. College has always been demanding both academically and socially. But students now are less mature and often not ready for the responsibility of being in college. It is really too easy to point the finger at parents who protect their children from life’s obstacles. Parents, who handle every difficulty and every other responsibility for their children from writing admission essays to picking college courses, certainly may contribute to their children's lack of coping strategies. But we can look even more broadly to the social trends of today. How many people do you know who are on medication to prevent anxiety or depression? The number of students who arrive at college already medicated for unwanted emotions has increased dramatically in the past 10 years. We, as a society, don't want to “feel” anything unpleasant and we certainly don't want our children to “suffer”. The resulting problem is that by not experiencing negative emotions, one does not learn the necessary skills to tolerate and negotiate adversity. As a psychologist, I am well aware of the fact that some individuals suffer from depression and anxiety and can benefit from treatment, but I question the growing number of medicated adolescents today. Our world is more stressful in general because of the current economic and political realities, but I don’t believe that the college experience itself is more intense today than that of the past 10 years. What I do think is that many students are often not prepared to be young “adults” with all the responsibilities of life. What does this, mean for college faculty and staff? We are required to assist in the basic parenting of these students - the student who complains that her professor didn't remind her of the due date for an assignment that was dearly listed on the syllabus and the student who cheats on an assignment in spite of careful instructions about plagiarism. As college professors, we have to explain what it means to be an independent college student before we can even begin to teach. As parents and teachers we should expect young people to meet challenges. To encourage them in this direction, we have to step back and let them fail and pick themselves up and move forward. This approach needs to begin at an early age so that college can actually be a passage to independent adulthood.
