Comma placement when using quotes that end with a question mark [duplicate]
Solution 1:
The quotes here delimit the article title. Since the comma is not part of the title, it belongs outside of the quotes. If this were a book title, it would be either italicized or underlined, but the comma would not. The same logic should apply here.
Solution 2:
There's no need for a comma after the quotation exactly because you have the question mark. It will look odd. If the question mark weren't there, you'd put a comma after the quotes.
