A question mark is used to end a question and in most cases, it immediately follows the question.
- What is the verdict?
- We all agreed that she was wrong, but, why didn’t you inform her?
However, when a question is followed by a clause that modifies it, the question mark is placed at the end of the statement.
- How could they hold him accountable for the theft, considering he had an alibi which was substantiated?
As it relates to question marks being used with quotation marks, if the information being quoted is a direct question, the question mark should be placed inside the quotation marks.
- “Who won the match?” Laura asked.
If the information being quoted is not a question, the question mark should be placed outside the quotation marks.
- Whose words are these “I are the one”?
