6.     A law requiring companies to offer employees unpaid time off to care for their children will harm the economic competitiveness of our nation’s businesses. Companies must be free to set their own employment policies without mandated parental-leave regulations.

Which of the following, if true, would most seriously weaken the conclusion of the argument above?

(A) A parental-leave law will serve to strengthen the family as a social institution in this country.

(B) Many businesses in this country already offer employees some form of parental leave.

(C) Some of the countries with the most economically competitive businesses have strong parental-leave regulations.

(D) Only companies with one hundred or more employees would be subject to the proposed parental-leave law.

 (E) In most polls, a majority of citizens say they favor passage of a parental-leave law.

这题谁告诉我Companies must be free to set their own employment policies without mandated parental-leave regulations.到底什么意思呢？怎么感觉和前面一句话是相反的观点？请教大牛！！！

我还没牛起来呢，呵呵……以下愚见

各公司可以自由规定他们自己的雇佣政策，不需要强制的parental-leave规定。

前面一句说（强制要求公司允许父母有unpaid time off去照顾孩子的）法律会伤害

国家商业的经济竞争力。后面一句话在站前面一句的立场上说，自由决定……
