Final answer:
Quebec was a successful colony in the 1600s due to the French focus on trade, harmonious relationship with Indigenous peoples, and expansion of their reach in North America.
Step-by-step explanation:
One reason that Quebec was a successful colony in the 1600s is that the French colonizers focused on trade rather than agriculture, which allowed them to profit from the lucrative fur trade and fishing industry in the region. The French also established a relatively harmonious relationship with the Indigenous peoples of Canada, who assisted them in acquiring furs and were often eager to convert to Christianity. Additionally, the French gradually expanded their reach from Quebec through the Great Lakes and down the Mississippi River, founding New Orleans near the Gulf of Mexico, which further solidified their control over the region.
