This is not clear to me.
Your example was:
Sub: GAG
CBAG, Ans: CDC
GEDC
The answer is mostly a fifth below excepted for the C which is answered with G instead of F if it were a pure transposition.
The problem, as I see it, is that in the subject in C major, C is the tonic. If the answer is modulating to the dominant (G), then clearly one cannot put an F in the answer, it would be a F#. But that would not be the tonic of G, so that's why you said one would put G instead, to remain in the tonality of G major and not shift back to C (as the natural F would).
Am I understanding this correctly?
Now back to my subject, I think I'd write a real answer to it, not a tonal answer, but I would slightly mutate the last note of the answer so as to be able to go back to the original tonic. That is, I would end the answer with EDC#
E, instead of the natural transposition up a fifth, which would be ending with EDC#
D (last 4 8th notes).
That single change of the last note of the answer would allow me to outline the dominant of D and go back to D in the next entry (A-C#-E-G, being the V7 of D). If I keep the D instead of E, then I need a bridge to modulate back to D after the answer is stated.
Is this analysis correct? Am I allowed to change the last interval of the subject in a "real" answer or is this only allowed in a "tonal" answer?
