This question concerns quotation marks occurring at the end of sentences.
Take this sentence, for example:
All he said was ‘I don’t know any more about that than you do’
The question is how to punctuate the end of the sentence:
a) All…than you do.’.
b) All…than you do.’
c) All…than you do’.
d) none of the above
I guess the essence of my question is whether one can end a sentence with a quotation mark. I didn’t pay much attention to this in the past and used to do as in a). I have recently been told that b) is correct. I am least inclined toward c).
