9. In recent years, there has been a dramatic decline in
the population of the shrike, a predatory bird that
inhabits flat land, such as farms and pastures. Some
ornithologists hypothesize that this decline is due to
the introduction of new, more effective pesticides to
control the insect species on which shrikes prey.
The answer to which of the following questions is
NOT relevant to evaluating the ornithologists’
hypothesis?
(A) Was there a decline in the shrike population
before the new pesticides were first used?
(B) Have shrike populations declined significantly
in those habitats where the new pesticides have
not been used?
(C) Have the new pesticides more significantly
reduced the population of insect species on
which shrikes prey than did the pesticides previously
used?
(D) Are insects that have consumed the new pesti-
cides more toxic to the shrikes that eat those
insects than were insects that consumed the
less effective pesticides?
(E) Are the new pesticides considered by most
people to be less harmful to the environment
than the old pesticides were considered to be?
