I think that 20% of smokers wanting to quit smoking would be too narrow because that is only 20 people out of 1,000,000 that want to quit smoking versus 90% of people that would lie to quit.
I believe the answer is c. An imposter is someone who impersonates/ disguises themselves as someone else
Where’s the options? i would gladly help !!!
The correct verb form would be a. came. Hope this helps!
