now I'm confusing about nor with "were" and "was" in parallel structure in sentence.
full sentence is that
Nor were these practices confined, as some scholars insist, to the later and supposedly decadent phases of the art Material, then, was utterly subservient to style.
I understood first meaning in parallel structure which is
Nor were these practices confined to the the later and supposedly decadent phases of the art Materials
but I confused second content. which is right between two meaning?
Nor was this practice utterly subservient to style (using 'nor' with 'was')
this practice was utterly subservient to style (not using 'nor' with 'was')
and second questions is why they use "was" instead of "were" at second parallel structure even though subject is "these practices"?
