272.
Eating saltwater fish may significantly
reduce the risk of heart attacks and also aid for sufferers of rheumatoid
arthritis and asthma, according to three research studies published in the New England Journal of Medicine.

(A) significantly
reduce the risk of heart attacks and also aid for

(B) be significant
in reducing the risk of heart attacks and aid for

(D) cause a
significant reduction in the risk of heart attacks and aid to（C）

(E) significantly
reduce the risk of heart attacks as well as aiding

想问一下为什么A选项的also aid for 不正确.
OG的解释是A: Aid for seems to be a noun, parallel to the
noun risk，indicating
that eating saltwater fish reduces aid for sufferers．不理解Aid for seems to be a noun是什么意思

谢谢了!

意思是A把两个介词结构用and平行连接,成了reduce的宾语

reduce (the risk of heart attacks and also aid for )

所以这里aid词性即为名词了

实际上,aid可以做及物动词,后面直接跟宾语
