Which possessive determiner should I use for the authorities? Its seems wrong, but their doesn't seem quite right, either. Example:
After examining all the evidence, I've found that the authorities are right and _____ critics are wrong.
If either its or their sounds perfectly fine to you, please say so and I'll use it. (In the example above, the is also an option, but it would work less well in my actual construction.)
If both of them sound off to you, as they do to me, please say so as well and I'll probably use the noun government instead (although I really prefer authorities in my context).
