I was harsher than was strictly necesary in my first comment, btw. That may make for comprehension difficulties.
"Free markets, economic interaction and profit motives are indispensable to liberty." What exactly is a "free market"? The thing as theoretically described in economics 101 books is not something that ever has existed or even ever could. "Economic interaction"? Between whom? What kind of economic interaction? Highway robbery is an economic interaction. Some forms of economic interaction are obviously indispensable to any human society, but "liberty" hardly enters the picture. Maybe he meant the unlimited right to economic interactions? Or to economic interactions approved of by all concerned (but those are very many - far more, in major economic transactions, than are given a hearing right now)? Similarly, "profit motives" are just a part of human nature. Acceptance of the fact that most people are in it with a profit motive is a necessary precondition to designing a working, sensible government program. "Liberty" has little to do with it.
Now how the hell do I answer the question with options like "I agree" or "I disagree" or "No opinion"?
You're right, this test leaves alot open to interpretation. I'll be honest some of the questions are pretty vague. Like question #14: "Abraham Lincoln's incompetence is responsible for the War of Northern Aggression." For me I can't agree, disagree, or have no opinion to because I believe that both sides to an extent were responsible for the Civil War and both guilty of moral failure.
