The citation in this sentence should be corrected to adhere to MLA format by replacing the year with the page.
MLA format is a specific style used by students and researchers to cite information taken from other sources in order to avoid commiting plagiarism, that is, the act of using other people's ideas without giving them credit for those ideas. MLA format is generally used when writing papers on topics related to the humanities field. The MLA guide states that in text citations (information taken from another source) should be followed by the last name of the author of that work and the page number. That is the reason why the year of publication that comes after the author's name in this sentence should be replaced with the page number.
