[讨论]OG31

OG31.Some who favor putting government 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 part system, which is now run by the governement.

Which if the followings, assming that it is a realistic possibility argues most strogly 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 memebers and eventually take over their leadership.
(B) Private environemtnatl groups might not always agree on the best ways to achieve conservation objectives.
(C) If they wished to extend the park system, the private environmental groups might have to seek contributions from major donors and the general public.
(D) There might be competition among pricate environmental groups for control of certain park areas.
(E) Some endangered species, such as the California condor, might die out despite the best efforts of the private encironmental groups, even if those groups are not hampered by insufficient resources.

ANS. A

可否说明答案为何是A?

题干是说私人环保企业比政府做得更好。 A是说如果那些搞环境破坏的企业或人加入了环保企业并当了领导，那私人环保企业对环境的保护就不一定有保证了，也就是说没有政府做得好了。
B是说不是所有的私人环保企业都同意什么是最好的环保方法。 但这不能否定是不是私人环保企业比政府做得更好。

消弱题

题干中其实是一个作者的推测：私有比政府更好。要找出能够逻辑上合理地否定这个推测的选项。

A选项：最后掌权私有企业的人是那些希望掠夺自然资源的人。把保护动物的工作交给这些人显然不合适。A正确

BCD指出了私有在结构上和功能上的一些特征，有些是劣势。但并不能得出，私有不比政府更好，因为选项没有指出政府没有类似的问题。错

E指出了一个特例，也不能否定，因为没有和政府的比较。错
