Public health expert: Until recently people believed that applications of biochemical research would eventually achieve complete victory over the microorganisms that cause human disease. However, current medical research shows that those microorganisms reproduce so rapidly that medicines developed for killing one variety will
only spur the evolution of other varieties that are immune to those medicines. The most rational public health strategy, therefore, would place much more emphasis than at present on fully informing people about the transmission of diseases caused by microorganisms, with a view to minimizing the incidence of such diseases.

Of the following, which one most accurately expresses the conclusion drawn by the public health expert?

(A) A medicine that kills one variety of disease causing microorganism can cause the evolution of a drug-resistant variety.
(B) A patient who contracts a disease caused by microorganisms cannot be effectively cured by present methods.
(C) There is good reason to make a particular change to public health policy.
(D) No one who is fully informed about the diseases caused by microorganisms will ever fall victim to those diseases.
(E) Some previous approaches to public health policy ignored the fact that disease-causing microorganisms reproduce at a rapid rate.
