economic policy matters，will develop policy relating to costbenefit analysis at the upcoming review and beyond．
A．The Principal Economist will become a board member．
B．The Principal Economist will deal with environmental matters．
C．The Principal Economist's major responsibility is to make certain policy．

【正确答案】 C

【答案解析】这是招聘首席经济学家的广告，说明其职位职责除了要在环境经济政策事务上向经理们和董事会成员提供建议“advising managers and board members 0n environmental economic policy matters”，还要制定关于成本一利润分析的政策“develop policy relating to cost-benefit analysis at the upcoming review and beyond”，而且后者为主要职责，因为用“as well as”连接的两个部分中，其后的部分为次要内容。因此，C为正确选项。
