When we look at the information present, we can see the name—Cassie Walker.  We can see the date—19 June 2009.  We can see the page number—89.  What might give us trouble is determining whether the title that is present is the title of an article or a magazine.  We can determine this, however, with the presence of the quotation marks.  The use of quotation marks around titles indicate the title of articles.  For larger works (such as books, magazines, newspapers, entire websites, music albums, etc.), the title will be placed in italics.  Thus, because there is nothing present in italics, we can determine that what is missing is the title of the magazine article.
