The A-spot marks the territory of Mexico and parts of what today is Texas, all that portion of the soil was controlled by Spain until the Mexican-American War where part of the territory was lost in the hands of the United States.
While the B spot marks the territory in which France settle down colonies in North America. The colonies endured for some centuries until the last French Indian War which resulted in the retirement of France from the colonies there and let Great Britain and Spain as the new owners of those territories.
