The population of peregrine falcons 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 falcons has been steadily increasing.
(C) Peregrine falcons, like other birds of prey, abandon eggs that fallen out
of the nest, even if the eggs remain intact.
(D) Starling, house sparrows, and blue jays-birds the peregrine falcon prey on
—were not adversely affected by DDT in their habitats.
(E) Other birds of prey, such as the osprey, the bald cage, and the brown
pclican, are found in the same area as is the peregrine falcon.
why A?
