OG19:In Mernia commercial fossil hunters often sell important fossils they have found, not to universities or museums, but to individual collectors, who pay much better but generally do not allow researchers access to their collections.To increase the number of fossils available for research, some legislators propose requiring all fossils that are found in Mernia to be sold only to universities or museums.

Which of the following, if true, most strongly indicates that the legislators’ proposal will fail to achieve its goal?

                                                                                       A

                                 Some fossil hunters in Mernia are not commercial fossil hunters, but ratherare amateurs who keep the fossils that they find.
                                                                                       B

                                 Most fossils found in Mernia are common types that have little scientific interest.
                                                                                       C

                                 Commercial fossil hunters in Mernia currently sell some of the fossils they find to universities and museums.
                                                                                       D

                                 Many universities in Mernia do not engage in fossil research.
                                                                                       E

                                 Most fossils are found by commercial fossil hunters, and they would give up looking for fossils if they were no longer allowed to sell to individual collectors.

有个疑问，对于措施目的性文章来说，削弱是当措施一定发生，但是目的达不到，这题措施是化石提供给学校和博物馆，目的是增加可供研究的化石数量，但是我觉得E选项的表述是措施没有发生（因为他们都不收集化石了还怎么提供给学校和博物馆），请大神们指教.

commercial fossil hunters找到的化石，基本都给了individual collectors；
为了让研究所用的化石数量增加，禁止commercial fossil hunters把化石给individual collectors；
==》这两句话中，第一句是事实，第二句其实是一个结论。结论得出的逻辑前提是：化石不给individual collectors，那么就会给research所用。（但是这个前提在题干中是没有的）
所以如果这个前提就不成立，那么结论不成立，所以反驳了结论。
