一道JJ 感觉很难选，NN帮看看

According to the information provided by police and fire department, the
city council proposed to have the alarm system installed given problems during
public vehicles accessibility.

A)    
during

B)    
of what

C)    
concerning…

D)    
regarding

感觉不是regarding就是concerning。可是好像og上不是很喜欢concerning，所以就选regarding了。

同求更好的解释。

我觉得没一个对~ ~

C,D一眼就觉得不对,concerning出现罗嗦~但A,B也不靠谱~

帮顶~

regard好像没有那种用法啊

the city council proposed to have the alarm system installed given problems during public vehicles accessibility

是不是那种if的省略句呢??

from longman:

concerning/regarding
/kənˈsɜːʳnɪŋ, rɪˈgɑːʳdɪŋ/ [preposition] formal about something or someone - use this especially to talk about information, ideas, or questions

For any details concerning a particular country you should check with the embassy.
