While antibiotics have done inestimable good to humankind over the last seventy years, there are several drawbacks to using antibiotics that, until recently, have been overlooked. The human microbiome, which consists of the trillions of bacteria that reside in each person’s body, is essential to good health. Specifically, the body contains and requires both “good” and “bad” bacteria. It is when the proper equilibrium between the “good” bacteria and the “bad” bacteria is disrupted that a number of health issues can emerge. Nonetheless, antibiotics indiscriminately kill both the “good” and the “bad” bacteria, so each course of antibiotics should be followed by a treatment that __________________________________

Which of the following most logically completes the argument above?

A. bypasses the microbiome altogether
B. targets and eliminates only the “bad” bacteria
C. restores the correct balance between the “good” and “bad” bacteria
D. purges the body of the remaining antibiotics completely
E. reverses any effects from the antibiotics

It is C .
Option A seems tangential ... It considers only Microbiome (Not all Good Bacteria)
Option B : Antibiotics cannot distinguish between good and bad bacteria as implied in passage , so in this case it seems again tangential
Option C : Yes True .. Since both good and bacteria are eliminated.balance has to be maintained after one is treated with antibiotics
Option D : OFS
Option E : Effects of Boitics (Not explicitly mentioned in passage , so didnt consider )

What's OA ??

C it is.

A. bypasses the microbiome altogether
From passage it is understood that microbiome is inclusive of all bacteria on which antibiotics acts/must act. hence bypassing microbiome does not make sense. incorrect.
B. targets and eliminates only the “bad” bacteria
A treatment that targets only bad bacteria which is required by body will cause further imbalance that is set in by antibiotics. hence incorrect.
C. restores the correct balance between the “good” and “bad” bacteria
Argument clearly states balance of good & bad bacteria is necessary. And antibiotics kills both good & bad bacteria indiscriminately there by causing imbalance in microbiome. Restoring this balance is the best course after antibiotics. CORRRECT
D. purges the body of the remaining antibiotics completely
Two issues with this:
1. The argument does not give enough information about whether there is any remaining antibiotics.
2. Even if there is some remaining it may not have that much impact as it would be less potent. - incorrect

E. reverses any effects from the antibiotics
we do not want to reverse effects of antibiotics, if we did then the positive use of antibiotics is negated -incorrect

Official Explanation
Answer: (C)



It is tempting to think answer (B), which says that the “bad” bacteria should be eliminated. However, the passage says that the “good” and “bad” bacteria are essential to the body, and that they have to the right balance—one that is upset during a course of antibiotics. Therefore, the best answer is one that speaks to the idea of restoring the correct balance of “good” and “bad” bacteria after the course of antibiotics. Therefore (C) is the best answer.

(A) is wrong because a treatment that “bypasses” the microbiome doesn’t deal with the initial problem: the potential imbalance between “good” and “bad” bacteria.

(B) See above.

(C) See above.

(D) It’s not that the antibiotics are bad. It is the effects of antibiotics (disruption of the balance between “good” and “bad” bacteria that needs to be addressed.

(E) may at first seem like the answer. But what is the point of taking a course of antibiotics only to undo the effects. Remember, the passage says that “antibiotics have done inestimable good”, so we don’t want to reverse all the effects only the ones that are negative—in this case the disruption in the balance between “good” and “bad” bacteria.
