问题     When fisheries have sunk or collapsed, one approach to fix the situation is to set up a marine reserve where fishing is banned. The idea is to provide relief to stressed fish stocks by providing safe living environment where fish can reproduce, and then spread out.
    Jennifer Caselle, a biologist from University of California, provided a local example of success. In 2003, the state of California set up a network of 12 marine reserves near Los Angeles and banned fishing in more than 488 square kilometers. By monitoring the area before and after, Caselle and her colleagues found that over 5 years there were 50％ more blue rockfish and other species targeted by fishing inside reserves than outside. There was no change in species that people don’t eat, suggesting that fishing restrictions were responsible for the recovery.
    Another success story comes from Australia, which created the first large marine reserve in the Great Barrier Reef Marine Park in 1975. After a major die-off of coral (珊瑚), the government decided in 2003 to rezone the park and increased the proportion of no-take areas from less than 5％ to 32％. Many fish species quickly doubled in size and numbers. The new reserves also seemed to improve ecosystem health in general, as outbreaks of coral-eating starfish were nearly 4 times more frequent on the reefs where fishing was still permitted.
    What makes a marine reserve successful? Taking a broad look at 56 marine reserves around the world, Joshua Cirtner of James Cook University examined the social and economic factors. The number of people living near the reserves played a big role in some cases. In the Caribbean, reserves near large populations tended to have less fish relative to unprotected areas than did reserves that were more remote. But the opposite was true in the Western Indian Ocean. It’s not clear why, but one reason could be that people tend to move to places with healthy marine reserves so that they can fish nearby.
    Another factor related to successful marine reserves was, as expected, compliance (遵从) with fishing restrictions. And that tended to be associated not just with enforcement, but more complicated social dynamics such as how well people work together and participate in research and management. "In areas where people work together to invest in their resources, we saw less people illegally catching fish inside marine reserves," Cinner said in a statement. "To get high levels of compliance with reserve rules, managers need to foster the conditions that enable participation in reserve activities, rather than just focusing on patrols."
Cinner would like to emphasize that people are more ready to comply with fishing restrictions ________.
选项 A、if they are legally conscious
B、if they are cooperative
C、when they enjoy rich resources
D、when they are supervised
答案B
解析 最后一段多句都提到work together、participation等词，表明“合作”和”遵从法规”两者存在着某种关系，而最后一句的内容表明“合作”能“让人们更好地遵从法规”，可见如果使人们更具有“合作性”，他们对法规的遵从性就更高，因此本题应选B。最后一段第2句和最后一句提到了人们对法规的遵从与法令的执行力度和监管的力度有关，但这些都不是Cinner研究的重点，因此，与此内容相关的A和D都不够恰当；C试图通过resources一词与原文产生联系，但事实上原文没有提到关于rich resources的内容。
