Answer 2

Politicians and the media work in close relationship to benefit each other.

One of these situations occurs when the politician helps the media by participating in programs so that they can increase their qualifications when necessary.

And, in return, the media helps politicians by presenting a disproportionate degree of beneficial coverage for that candidate and his initiatives.
