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.



Can someone explain why option a is incorrect

C is correct. Good question.

'therefore' in the last sentence is the key: The conclusion is

public health strategy would place much more emphasis <than at present> on fully informing people about blah blah

'than at present' tells us that there is scope of editing/revising the publick health strategy.

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. <<< This is not conclusion. Its given in the passage as premises

(B) A patient who contracts a disease caused by
microorganisms cannot be effectively cured by
present methods. <<< Can not say this from given info

(C) There is good reason to make a particular
change to public health policy. << Correct

(D) No one who is fully informed about the diseases
caused by microorganisms will ever fall victim
to those diseases. << given info doesn't say this.

(E) Some previous approaches to public health
policy ignored the fact that disease-causing
microorganisms reproduce at a rapid rate << Partially true, but again, not conclusion. Added premises to the first sentence.

Ppl belief: Biochem could achve vctry over micro until rec.
BUT, killing 1 -> other micro evolves
THEREFORE, MOST rational public health strat is spread INFO

(A) is an evidence Not the Point

(B) is not supported by argument; in fact, it says it can kill one micro (BUT cause others to evolve)

(C) is exactly the point (change public health policy/strategy)

(D) is extreme / not really supported by argument

(E) is not the point

I think A only represents information of this part "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 primary purpose of this passage is to urge a change in public health strategy

I disagree - I think that this question is weak, because the passage does not give information telling us what the current health care policy is; merely that a certain tactic is more rational.
