1. If my memory serves me well, the main reason why Europeans wanted to find a Northwest passage was to find a better water route to Asia. Some of European countries like England were relatively poor so they needed to find new trading routes and sources of goods. So the answer is option c).
2. I am definitely sure that the main factor which led the French to create the settlement of Quebec was the fur-trade, as they believed that establishing a settlement would increase the price of beaver fur. Their trading posts were set up all over America. So the correct option is d).
3. As far as I remember, the Iroquois dominated the fur trade competition in the East and attempted to hold monopoly over guns by preventing other tribes to acquire it. So the most suitable option is b).
