Place a question mark only after a sentence that asks a question. For example, you would place a question mark after the following sentence: "Would you like a chocolate?" However, you would not place a question mark after the following sentence: "I would like a chocolate, please."
Include the question mark inside the quotation marks only if the question mark is part of the quoted material. Otherwise, the question mark rests outside of the quotation marks. For example, in the following sentence, the question mark would go inside the quotation marks: "She asked, 'May I have a chocolate?'''
Leave one space between the quotation mark and the next letter in the following word, rather than two, or no spaces at all.
