awareness about vs awareness of

[2010gmat]

Since the last election, the lobbying effort initiated by environmental organizations, homeowners, and small business owners have increased awareness of pending environmental legislation.

"¢ have increased awareness of pending environmental legislation
"¢ have increased awareness about pending legislation dealing with the environment
"¢ has increased awareness about pending environmental legislation
"¢ has increased awareness of pending environmental legislation
"¢ has increased awareness of environmental legislation that is still pending

Which is idiomatically correct : awareness about or awareness of ??

[nervesofsteel]

IMO C

awareness about is correct

awareness of can mean ..awareness of a particular thing...
eg : awareness of people...

but here awareness is used for awareness about.....

has increased awareness about pending environmental legislation

...subject is the singular "lobbying effort". So,plural verb "have" is incorrect.

awareness about - to raise information about something
e.g. raise awareness about safety issues on roads in India

awareness of - for putting knowledge about something
The students have little awareness of regulations

So choice D is correct
