Laws prohibiting the sale of cigarettes to minors and proscribing smoking in theater and other public places were enacted as early as the 1890’s the primary concern of the latter regulations, however were not considerations of health but instead they were for fire prevention.
A) were not considerations of health but instead they were for
B) were not considerations of health but were instead
C) was not considerations of health but instead for
D) was not considerations of health rather it was for
E) was not considerations of health but rather of
ANS:E
我想
這裡要用單數,所以A和B不對
C ->應該變成 instead it was for
D ->語意有點怪,因為用rather
只剩E了
請教更仔細的解答好釐清思路
