GWD21-Q21 谁能翻译一下... 实在不懂

GWD21-Q21:

Which of the following most logically completes the passage?

 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\

求助,, 看了几遍实在不懂..   为什么选项A

终于明白了,

take hold (To become established:扎根)

A , 削弱,   S.a不能扎根,  但由于 S.s的出现使其扎根成为可能!

Which of the following most logically completes the passage?

 

问怎么能合理完成句子

 Mastitis is an infection of the udder in cows that, although not dangerous, causes them to

M是一个传染在一个UC上的,虽然不危险,但搞的奶恶心。

give poor-quality milk.  Most cases of mastitis are caused by the bacterium Staphylococcus

说大多数M是被SA导致

aureus, against which antibiotics are ineffective.  However, a related bacterium,

说反对这个M用啥东西是没用的。但是涅,这个相关的菌啊,

Staphylococcus simulans, quickly clears up even severe infections of S. aureus simply by

SS能很快地杀死SA通过啥涅,是通过代替SA通过SS

displacing the bacteria.  S. simulans is nevertheless unlikely to become the preferred

然而这个SS的这个菌阿不是治这个M这个病的首选。所以

treatment for cases of mastitis, since ______.

A.      certain dangerous bacteria that normally cannot take hold can do so in the presence of S. simulans
                

A说某种危险的(菌啊不能保持的)菌能做在SS

B.       the current resistance of S. aureus to antibiotics derives in part from a past pattern of overuse of those antibiotics

BA这个东西用于干啥的,是从一个啥鸟东西里来的。

C.      the milk from cows infected with S. aureus is generally not of such poor quality as to be entirely unusable

C说咋着的和SS的这个奶啊是一般不恶心的。

D.      careful farming practice can reduce the incidence of mastitis to a minimum

D.说种地呀能减少M

E.       the only symptom of mild cases of mastitis is the deterioration in the quality of the milk produced

E说奶啊of Mof S这个东西
            
是牛奶之量的一个啥东西。

 

如果这样还不明白我就自杀了。

原文:SS不能用来杀菌是因为?
A:在SS之前,有种危险的病菌和SS的作用一样并不能产生效果。

由A推知SS不能产生效果,所以不用SS
