仔细看下C和D的本质区别 C: the practice cannot achieve its objective. D: the policy is not needed.
再看下bf2中the goal of providing international experience,那么显然目标应该是获取国际经验,并且提到could be achieved in other ways.这已经说明this way(the practice)可以达到这个目标,只是我们不需要(is not needed)采用这种方式(the policy).
I chose D mainly because D correctly reiterate that the conclusion (therefore, .....Hachnut should discontinue this sponsorship of this program) of this passage is "not needed," instead of "cannot not achieves its objective."
"both this function and the goal of providing international experience could be achieved in other ways." 就是说可以用其它的方法长国际经验,那这种花钱不讨好的培训当然是“not needed”了。。
