  To save the Amazon rain forest from destruction, it is necessary to find a commercially profitable alternative to logging. Harvesting the fruits and nuts of the rain forest, however, is not a good alternative. To make harvesting commercially profitable the ecological interrelationships of rain forest organisms would have to be transformed or destroyed.

  Which of the following, if true, gives the strongest support to the argument above?

  A:Market research surveys have established that over 76 percent of the consumers who regularly purchase fruits and nuts harvested from a rain forest are not aware of the origin of those fruits and nuts.

  B:The current level at which nuts in the Amazon rain forest are being harvested is already causing starvation among many species of birds and mammals that would otherwise have eaten the nuts.

  C:Some companies harvesting rain forest fruits and nuts impose on their commercial clients a 5 percent environmental fee to restore logged areas in the rain forests.

  D:Indigenous people in the Amazon rain forest receive only a subsistence-level income for harvesting nuts and for logging hardwood trees.

  E:The harvesting of plant material for poisons, medicines or foods has been part of the traditional culture of the rain forest peoples and has not noticeably damaged the rain forest.

  最佳解析:

  本题支持上面论述,上面结论为最后一句话:“为了使雨林经济上有利可图,雨林生态有机体的相互关系可能不得不改变或摧毁。”(A)消费者是否意识到水果是否来自雨林与上面无关。(B)指出目前雨林的坚果收获水平已经使动物饥饿,支持了会使雨林生态关系改变或破坏。(C)(D)(E)均说明不了对雨林生态的作用,所以(B)is correct。

  答案:B
