Question Marks [ ? ]

1) Use a question mark only after a direct question.
For example:

• Can you help negotiate the contract?
• But: I asked her if she can help negotiate the contract.

2) Use a question mark when a sentence is part statement and part question.
For example: You are available to negotiate, are you not?

3) Use a question mark when it is part of a quotation.
For example: The Chairman asked, “Is the meeting duly convened?”
