Explanation: The circle of fifths is a circle that, like a clock, has 12 symbols in it, where the symbols are the 12 notes that we know, and the consecutive symbols are notes that are distanced by a fifth, so you will have:
G-D-A-... etc
The circle of fifths shows both major and minor key signatures (knowing that with the same notes that you make the major scale of C you can make the minor scale of A, this has a lot of sense) so the statement is false.
