Why does F not work as I thought that the other person could serve as an intermediary and provide feedback to the person wanting to publish? Thanks!

Hey Kalina,
An "intermediary" is a third person who mediates, or helps to negotiate, between two other people. In the sentence, though, only two people, the journalists, are mentioned. Since there is no third party, there can't be an intermediary.
Hope that clears it up!

(C) doesn't work because "impediment" is a negative word. It would mean that one journalist was trying to publish, and the other was causing a problem by stopping it. We want words that imply collaboration, not obstacles.
