Which preposition (with/by/about/for) is correct in this sentence? Do they have the same meaning?
Air pollution is a problem that every person should be concerned with/by/about/for.
they all make sense in that sentence apart from 'for', they just have different meanings
air pollution is a problem that every person should be concerned with
air pollution is a problem that every person should be concerned by
air pollution is a problem that every person should be concerned about
they all have a similar enough meaning that they (for the majority of the time) can be used interchangeably
I m not expert but i m gonna try to help .. all to do to make it easy is transforming the sentence to become : every person is concerned ( by / with / about / for ) air pollution .. i think things becomes a little clear now ,, the correct answer is with
