[語文] GWD21-21
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 severeinfections 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
這題答案是A，我當初寫A是因為其他都被我刪光了所以才選這個答案。
想請問各位高手這A選項的翻譯到底要怎麼解釋會比較好阿?
謝謝~
