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? ['Some fossil hunters in Mernia are not commercial fossil hunters, but rather are amateurs who keep the fossils that they find.', 'Commercial fossil hunters in Mernia currently sell some of the fossils they find to universities and museums.', 'Many universities in Mernia do not engage in fossil research.', '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.']
