According to MLA Citation Style Guide, the proper way to make a parenthetical citation in this paraphrese would be as follows:
("Was Emerson Lying To His Constituents?" A2)
Since the paraphrase has no known author,the parenthetical should contain the title of the article or book from which the citation was taken followed by the page number. Also, the title should be in quotation marks if it's short tor italicize it if it's longer.
