Hardin argued that grazing land held in common(that is ,open to any user)would always be used less carefully than private grazing land.each rancher would be tempted to overuse common land because the benefits would accrue to the individual,while the costs of reduced land quality that results from overuse would be spread among all users.but a study comparing 217million acres of common grazing land with 433 million acres of private grazing land showed that the common land was in better condition
Which of the following, if true and known by the ranchers, would best help explain the results of the study?
(A) With private grazing land, both the costs and the benefits of overuse fall to the individual user.
(B) The cost in reduced land quality that is attributable to any individual user is less easily measured with common land than it is with private land.
(C) An individual who overuses common grazing land might be able to achieve higher returns than other users can, with the result that he or she would obtain a competitive advantage.
(D) If one user of common land overuses it even slightly, the other users are likely to do so even more, with the consequence that the costs to each user outweigh the benefits.
(E)There are more acres of grazing land held privately than there are held in common
og的解释
The study indicates that common lands are in better shape than private lands. The best answer, D, indicates that, contrary to Hardin’s claim, it is in each rancher’s self-interest not to overuse common land, which would explain why common lands are in relatively good shape.
对选项不理解
原文要解释的是"H认为grazing land held in common会被过度使用,而实际情况和这正好相反".
D是对的.D说了如果过度使用的话,那么使用的费用就会超出利润. ---> 所以人们就不会过度使用grazing land held in common.
ABE是无关项.C解释的是H的观点.都是不对的.
