答案选C
我首先排除了ABE选项，因为they与句子的单数主语不一致。但关于C和D选项中，有三点不明白：
1.选C不选D是不是因为D调换了句子的顺序，改变了句子的强调重点？
2. C选项this year 73% will be这个结构，为什么对？
3.C 选项36 percent of the nation’s 607 HMO’s 后面的谓语动词为什么用复数？

46 应该是were profitable。参见下面的解释。

Fractional expressions such as half of, a part of, a percentage of, a majority of are sometimes singular and sometimes plural, depending on the meaning. (The same is true, of course, when all, any, more, most and some  act as subjects.) Sums and products of mathematical processes are expressed as singular and require singular verbs. The expression "more than one" (oddly enough) takes a singular verb: "More than one student has tried this."

   * Some of the voters are still angry.
   * A large percentage of the older population is voting against her.
   * Two-fifths of the troops were lost in the battle.
   * Two-fifths of the vineyard was destroyed by fire.
   * Forty percent of the students are in favor of changing the policy.
   * Forty percent of the student body is in favor of changing the policy.
   * Two and two is four.
   * Four times four divided by two is eight.

as many as  [people] are enrolled in--比较对象people被省略。
请注意：four people as many as are enrolled in--错误。这里必须是非限定性。

40题大全有答案。
The phrases equivalent to in A, the equivalent of in B, and equal to in C have too broad a range of meanings to be used precisely here: that is, they can suggest more than merely numerical equality. Also, as quantitative expressions, equivalent and equal often modify nouns referring to uncountable things, as in “an equivalent amount of resistance” or “a volume of water equal to Lake Michigan.” To establish numerical comparability between groups with countable members, the phrase as many as is preferable. Choice D, however, uses this phrase improperly in comparing eight million people to enrollment, not to other people. The comparison in E, the best choice, is logical because people is understood as the subject of are enrolled.
