问题如下：
Recently Analyst Bob is studying regulatory environment of a country. The energy industry in this country enforces a new rule with some intended and unintended results. Bob states that some unintended results could be distinguished in regulatory documents and unintended results will cause high unanticipated costs. Bob’s conclusion is
选项：
A. only correct about regulatory documents .
B. only correct about unanticipated costs.
C. both correct.
解释：
C is correct.
考点：Baisc Concepts of Cost-Benefit Analysis
解析：监管文件可以用以改善监管措施，它在一定程度上是可以识别部分监管措施带来的非故意而为的结果。如果非故意而为的结果产生，那么实行监管政策产生的非预期成本也会增加。所以Bob的说法都是正确的。
“Bob states that some unintended results could be distinguished in regulatory documents” 对解答里那个“下不下雨都要带伞来预防”的解释不太能接受...既然是unintended，就已经是意料之外的结果了，说明是没有考虑到的结果，那又如何在文件里体现呢？ “and unintended results will cause high unanticipated costs.” unintended results 也可能cost nothing，不明白这里如此肯定的结论是怎么判断出的... 这道题的知识点在什么地方，打算重新学习一下（哭泣）
