Questions 83 to 86 are based on the following passage. Engineering students are supposed to be examples of practicality and rationality, but when it comes to my college education I am an idealist and a fool. In high school I wanted to be an electrical engineer and, of course, any sensible student with my aims would have chosen a college with a large engineering department, famous, reputation and lots of good labs and research equipment. But that’s not what I did. I chose to study engineering at a small liberal-arts university that doesn’t even offer a major in electrical engineering. Obviously, this was not a practical choice; I came here for more noble reasons. I wanted a broad education that would provide me with flexibility and a value system to guide me in my career. I wanted to open my eyes and expand my vision by interacting with people who weren’t studying science or engineering. My parents, teachers and other adults praised me for such a sensible choice. They told me I was wise and mature beyond 18 years, and I believed them. I headed off to college sure I was going to have an advantage over those students who went to big engineering “factories” where they didn’t care if you had values or were flexible. I was going to be a complete engineer: technical genius and sensitive humanist all in one. Now I’m not so sure. Somewhere along the way my noble ideals crashed into reality, as all noble ideals eventually do. After three years of struggling to balance math, physics and engineering courses with liberal-arts courses. I have learned there are reasons why few engineering students try to reconcile engineering with liberal-arts courses in college. The reality that had blocked my path to becoming the typical successful student
