I would like to know how to properly write, somewhere in a paragraph, the phrase "Why questions". By which I mean questions of the form "Why... ?".
The sentence I would like to write is "How to answer why questions." How do I format it?
Possibilities:
- How to answer why questions.
- How to answer why questions.
- How to answer why? questions.
- How to answer 'why' questions.
- How to answer "why" questions.
- How to answer "why?" questions.
I thought 3 would be best but I would appreciate a second (third, etc.) opinion.
