The parts of the scenario in which the reporter's right to free press is being restricted are:
3 and 4
-
In point 3, the editor demanding the reporter name his sources can be seen as a restriction on the reporter’s ability to protect the confidentiality of anonymous sources, which is an important aspect of journalistic integrity and the freedom of the press.
-
In point 4, the government official reviewing the story and refusing to let the newspaper publish it is a direct interference with the press's right to report on matters of public interest.
Thus, the correct answer is 3 and 4.
