　　例： The population of peregrine ns declined rapidly during the 1950’s and 1960’s and reached an all-time low in the early 1970’s. The decline was attributed by scientists to the widespread use of the pesticide DDT in rural areas Which of the following, if true, gives the strongest support to the scientists’ claim? (A) DDT was not generally in use in areas devoted to heavy industry
　　(B) In the time since the use of DDT was banned in 1972, the population of peregrine ns has been steadily increasing (C) Peregrine ns, like other birds of prey, abandon eggs that have fallen out of the nest, even if the eggs remain intact (D) Starlings, house sparrows, and blue jays-birds the peregrine n preys on were not adversely affected by DDT in their habitats
　　(E) Other birds of prey, such as the osprey, the bald eagle, and the brown pelican, are found in the same areas as is the peregrine n.
