(从第14秒开始，原文重现：The area was named Cape Cod because there were so many cod fish in the water just off its shores. So many that the first Europeans who fish there in the seventeenth century reported it was better than Newfoundland Canada.)
由此可知教授之所以将科德角和纽芬兰进行对比，是为了突出科德角的鳕鱼数量非常多。所以B选项正确。

由此可知私有化并不能有效的解决环境资源的管理问题。所以A选项正确。
