I am new to this forum.
my book is like question and answers
which have more than 500
each question have four answers
and end with new line Answer
Footnote to this new line
and select Correct answer which is within "quates"
at last removes quates in answer and source

Congratulations.

I understand that English might not be your first language but you haven't actually asked a question here. I think you would need to post a sample of your document and tell us what you want to do.
