The correct response is 2 and 3.
-
Part 2: The editor demanding that the reporter name his sources can be seen as a restriction on the reporter's ability to protect their sources, which is a key aspect of free press and journalistic integrity.
-
Part 3: The government official's refusal to let the newspaper publish the story represents a direct intervention and restriction on the freedom of the press, limiting the newspaper's ability to inform the public about the illegal activities.
Parts 1 and 4 do not pertain directly to the restriction of the reporter's rights under the concept of free press.
