What was not one of the major factors of the victory of america in the revolutionary war?

the courage of the continental soldiers,
the leadership of george washington,
aid from foreign countries,
or the superior training of the continental soldiers?

The one that was not a major factor of the victory of America in the revolutionary war is :
The superior training of the continental soldiers
Most of the continental soldiers had very little training and experience when they join the revolutionary war

hope this helps
