因果型结论or条件型结论？

31. Some who favor putting governmental enterprises into private hands suggest that conservation objectives would in general be better served if private environmental groups were put in charge of operating and financing the national park system, which is now run by the government.

Which of the following, assuming that it is a realistic possibility, argues most strongly against the suggestion above?

A. Those seeking to abolish all restrictions on exploiting the natural resources of the parks might join the private environmental groups as members and eventually take over their leadership.


在此只贴原题和正确答案，有一个问题：
题干的premise是conservation在私企手中会更好
WEAKEN的手段是说私企可能抱着掠夺资源的心态，导致conservation变差。

这道WEAKEN是属于  因果型结论中的割断因果（或有因无果或有果无因），使前提原因变化（补充私企的掠夺意愿），推不出conservation变好。

还是条件型结论（如果是的话，那这道题的条件就是：私企不能抱着掠夺资源的想法，才能起到conservation 的作用）


因果型和条件型一直分不清，麻烦NN解答！
