How do you properly quote within a quote?

Question

Should you use quotes or brackets? In APA format, if that matters.

Answer 1

John said,"Margie said,'This is how you quote within a quote.'"

Answer 2

take a new line and indent it, say for example

"Marjorie said;

            "I don't believe I know that one"

to which George replied with an astounding tone of sarcasm;

            "That's because I haven't invented it yet"

looks better with longer quotes obviously but this is just an example

Answer 3

"This is how according to 'MLA style,' one quotes within a quote."

Answer 4

idk but I think I remember for high school don't you use

" and " for the big quote and ' and ' for the inside quote.
