The reporter's right to free press is being restricted in parts 2 and 4 of the scenario.
- In part 2, the editor's demand for the reporter to reveal his sources can be seen as a restriction on the reporter's ability to protect his sources, which is an important aspect of press freedom.
- In part 4, the government official's review and refusal to let the newspaper publish the story directly restricts the newspaper's ability to report on the illegal activity.
Therefore, the correct answer is 2 and 4.
