一个解释矛盾性的题目?

Since the introduction of the Impanian National Health Scheme, Impanians (or their private insurance companies) have had to pay only for the more unusual and sophisticated medical procedures. When the scheme was introduced, it was hoped that private insurance to pay for these procedures would be available at modest cost, since the insurers would no longer be paying for the bulk of health care costs, as they had done previously. Paradoxically, however, the cost of private health insurance did not decrease but has instead increased dramatically in the years since the scheme introduction.

Which one of the following, if true, does most to explain the apparently paradoxical outcome?

(A) The National Health scheme has greatly reduced the number of medical claims handled annually by Impania's  private insurers, enabling these firms to reduce overhead costs substantially.

(B) Before the National Health scheme was introduced, more than 80 percent of all Impanian medical costs were associated with procedures that are now covered by the scheme.

(C) Impanians who previously were unable to afford regular medical treatment now use the National Health scheme, but the number of Impanians with private health insurance has not increased.

(D) Impanians now buy private medical insurance only at times when they expect that they will need care of kinds not available in the National Health scheme.

(E) The proportion of total expenditures within Impania that is spent on health care has declined since the introduction of the National Health scheme.

笔误,是D,改正。
理解:由于大部分医疗费都被医保COVER,只有昂贵的没有,那么买此类保险当然要贵。

文中已讲,医保后只有某些特别的东西才用投保,可以理解为普通的,医保都管了,只有复杂的,才须投保,肯定是贵的服务项目,那么保费当然高
