Question marks are a little more complicated.
They are placed inside of quotation marks when they are part of the quoted matter. Problems arise when the question mark attaches not to the material inside the quotation marks, but rather to the frame of the sentence. I realize I have two complete sentences, but I am not sure if the parentheses affect the period after commentator . I shall be giving a paper at a society meeting with the American Philosophical Association meeting in Los Angeles, with commentator. The punctuation is fine.
