一道题目都读不懂的逻辑求助：（

Which of the following best completes the passage
  below?

“Government” does not exist as an independent entity
defining policy. Instead there exists a group of demo-
cratically elected pragmatists sensitive to the electorate,
who establish policies that will result in their own
  reelection. Therefore, if public policy is hostile to, say,
  environmental concerns, it is not because of govern-
  mental perversity but because elected officials believe
  that—
  (A) environmentalists would be extremely difficult to
      satisfy with any policy, however environmentally
      sound
  (B) environmental concerns are being accommodated
      as well as public funds permit
  (C) the public is overly anxious about environmental
      deterioration
  (D) the majority of voters vote for certain politicians
      because of those politicians’ idiosyncratic posi-
      tions on policy issues
  (E) the majority of voters do not strongly wish for a
      different policy

补充材料上面的，看不懂题目阿：（ 那位大虾能解释一下阿。谢了

在制定政策时，政府不是作为一个独立存在的实体的。而是，政府中有一些被民主选举出来的对选民的态度很敏感实用主义者，他们制定的政策要能够让他们连任。因此，如果公共制度对，比如，环境问题持敌对态度，不是因为是政府的荒谬行为，而是因为在野党认为-----

E，大部分选民不赞同不同的政策，所以为了连任，在野党就选择了这个政策。

希望说的还算明白

看懂题目就不难理解了，谢谢vicky和shasha

你看句子时如果看不懂，就去找主句的主语和谓语，至少能看个大概。我没辙时就这样干，往往能看懂个大概。

Instead there exists a group of demo-
cratically elected pragmatists sensitive to the electorate,
who establish policies that will result in their own
  reelection.

句子结构是不是应该改错啊. who是修饰选民的, 应该修饰pragmatists吧.
