Please explain, someone, what's wrong with "כמה סופרמרקטים נמצאים בעיר הזאת"??
Should be accepted, report it
It there a way to report ex post facto, or do you mean should the question come my way again?
I don't know of any way to report ex post facto. However, I can do it for you right now.

Is עיר feminine? Why הזאת
Yes, it's feminine. And to make it even more confusing, its plural is ערים (arím).
