Question

Which answer choice best describes when single quotation marks should be used?

A.
for quotations within quotations

B.
for the titles of poems

C.
for the titles of stories

D.
for letters that represent themselves

Answer 1

I do a lot of reading and in my experience the answer would be A. For example:
"a quote within a quote 'would look like this' " 
(not the best example, but it works)
I hope I could be of help
