Question ID:PT12 S1 Q12 Passage:In 1980 health officials began to publicize the adverse effects of prolonged exposure to the sun, and since then the number of people who sunbathe for extended periods of time has decreased considerably each year. Nevertheless, in 1982 there was a dramatic rise in newly reported cases of melanoma, a form of skin cancer found mostly in people who have had prolonged exposure to the sun. Stem:Which one of the following, if true, helps to resolve the apparent discrepancy in the information above? Correct Answer Choice:DChoice A:Before 1980 a considerable number of the people who developed melanoma as a result of prolonged exposure to the sun were over forty years of age. Choice B:Before 1980, when most people had not yet begun to avoid prolonged exposure to the sun, sunbathing was widely thought to be healthful. Choice C:In 1982 scientists reported that the body’s need for exposure to sunlight in order to produce vitamin D, which helps prevent the growth of skin cancers, is less than was previously thought. Choice D:In 1982 medical researchers perfected a diagnostic technique that allowed them to detect the presence of melanoma much earlier than had previously been possible. Choice E:Since 1980, those people who have continued to sunbathe for extended periods of time have used sunblocks that effectively screen out the ultraviolet rays that help cause melanoma.
