The most compelling evidence of the risks of carcinogenic effects of
environmental pollutants comes from animal data, such as the reproductive
failure and anomalous development witnessed in birds and fish exposed to DDT.
Line But can human health effects of a compound be judged without a consensus of
(5) independent epidemiological studies and experimental findings on humans
subjects? One would argue not, even though increases in breast cancer have
recently been correlated to exposure to environmental pollutants. Scientists
reviewing worldwide morbidities of certain hormonally responsive organs have
found that while the incidence of breast cancer has been increasing, that of
(10) cancer of the uterus, another hormonally responsive organ, has been
decreasing. There is thus no evident increase in uterine cancer that would
support the claim that a pollutant is causally responsible for the recent increase
in breast cancer. It has been suggested that the increase may be the result of
increased diagnosis, and geographical differences in cancer susceptibility are so
(15) large that the currently available statistics do not permit a definite conclusion.
According to the passage, which of the following findings confirms the author’s conclusions concerning disease morbidity rates associated with pollutants?
选项
A、Certain organs are more reponsive than others to the hormones created by environmental pollutants.
B、The incidence of breast cancer correlates with the presence of environmental pollutants.
C、A great deal of evidence has been amassed linking environmental pollutants with cancer in animals.
D、Cancer diagnosis has become more reliable than it once was.
E、Cancer of the liver, an organ that is hormonally responsive to environmental pollutants, is rising globally.

D
