Critical Reasoning

Mastitis is an infection of the udder in cows that, although not dangerous, causes them to give poor-quality milk. Most cases of mastitis are caused by the bacterium Staphylococcus aureus, against which antibiotics are ineffective. However, a related bacterium, Staphylococcus simulans, quickly clears up even severe infections of S. aureus simply by displacing the bacteria. S. simulans is nevertheless unlikely to become the preferred treatment for cases of mastitis, since .....
A. certain dangerous bacteria that normally cannot take hold can do so in the presence of S. simulans.
B. the current resistance of S. aureus to antibiotics derives in part from a past pattern of overuse of those antibiotics
C. the milk from cows infected with S. aureus is generally not of such poor quality as to be entirely unusable
D. careful farming practice can reduce the incidence of mastitis to a minimum
E. the only symptom of mild cases of mastitis is the deterioration in the quality of the milk produced

My pick is A.

A provides a reason as to why . aureues is not prefrable.

B in no way can be the answer. Infact it is out of scope of the argument.

the answer should be A
when S simulan can replace the S au therefore can MAYBE increase the quality of milk however if replacing S au by S simulan, another dangerous bacteria ( means another desease) dealing with S simulan, the deseases that the farmer cant handle would happen
does it help?

IMo A

IMO A.

A. certain dangerous bacteria that normally cannot take hold can do so in the presence of S. simulans.
Correct. Since this option talks about the side effects of using S.siumalans. Thus, A.

B. the current resistance of S. aureus to antibiotics derives in part from a past pattern of overuse of those antibiotics.
This option focusses on the resistance of S. aureus to antibiotics i.e., why anitbiotics are no more effective for curing the disease whereas, the statement flow of passage asks us for why S.simulans cannot be used to cure the disease. Thus, not acceptable.


Hope it helps!

IMO A..

Staphylococcus simulans, which inhibits Staphylococcus aureus, will create an environment in which many other bacterias grow..
