Doctors have suggested that women should take the Pap test every three years to screen for cervical cancer. Since the Pap test is meant to detect abnormalities that may lead to invasive cervical cancer, these abnormalities can be treated before cancer develops. Most invasive cancers of the cervix can be prevented if women have Pap tests regularly.

The answer to which of the following questions would be most important in determining whether implementing the suggestion is likely to achieve the desired result?

(A) What percent of women in whom abnormalities are detected actually get invasive cancer of the cervix?

(B)What is the time lag between appearance of abnormalities and subsequent development of cervical cancer?

(C) Do the insurance companies cover the cost of Pap test?

(D)Are the causes of development of abnormalities identified?

(E)Do we have treatment for the abnormalities so that cancer does not develop?
