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.

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OG的解释不理解.为什么D表明是OWNER自己的利益,就可反对h的结论呢?
