Answer:

find()

Explanation:

When dealing with MongoDB the method that needs to be used in this scenario would be the find() method. This method basically returns all of the records that exist in the collection on which it is called, if no parameter is passed. If you pass a parameter/expression then only the records that match completely the expression will be returned to the user, otherwise nothing is returned. For example, on a database (db) we would call the following

db.find() ... This will return all records

db.find({specific}) ... This will return only the records that match specific.

Early American newspapers were partisan and sensational, but in the late nineteenth and early twentieth century, they started to become more objective and professional. Many journalists have been confused by the fall in recent years since readers don't seem to be all that interested in reading newspapers. The decline in newspaper production is caused by a number of factors, including social media, corporate ownership, internet access, and advertising. Three of the four primary purposes of mass communication—surveillance, correlation, and cultural transmission—involve journalism to a significant extent.
