Which word does not belong to others in the context of newspaper?

The correct answer is option 4: Reader 

• Writer – a content creator (which includes editorial writers, columnists, etc.)

• Reporter – a specific type of writer focused on factual news reporting

• Publisher – responsible for the production, business, and distribution aspects 

The first three roles (Writer, Publisher, Reporter) are all actively involved in the process of creating, producing, or distributing the newspaper itself. The "Reader," however, is the consumer of the newspaper, rather than a direct participant in its making. Therefore, the word that does not belong to the others in the context of a newspaper is Reader.
