There are two possible answers to this question so I suggest that you consult your textbook and/or your class notes to see which one your teacher thinks is the best answer.  I would argue that Option D is the best answer, but Option A is also possible and is, in fact, connected to Option D.

There are two possible answers to this question so I suggest that you consult your textbook and/or your class notes to see which one your teacher thinks is the best answer.  I would argue that Option D is the best answer, but Option A is also possible and is, in fact, connected to Option D.

National health care provided by the government would be immensely expensive.  It might not be more expensive than what we have now, but the costs would be easier for people to see.  Such a program would inevitably raise taxes and would make people very unhappy.

This is how Option A leads into Option D.  One reason why national health care would be “too expensive” for Americans is because our political culture is one that does not accept high levels of taxation.  Other industrialized countries’ people are willing to pay higher taxes for such systems.  In addition, the idea of the government providing health care generally goes against our political culture.  We think that it is better for private businesses to provide things like health care and so most Americans reject the idea of a national system along the lines of Britain’s National Health Service.

I think, then, that Option D is a better answer than Option A, but you should check your class materials to be sure.
