The correct answer to this open question is the following.
During the French and Indian War that started in 1756 and ended in 1763, both nations fought for territory disputes. French troops used the land to built strategic forts such as Forts Duquesne in the Ohio River. Then, many Native American Indian tribes allied on the side of the French because they treated Indians much better than the English colonist. The key issue was that the French did not want the land to settle in or to send French people to inhabit those lands. They were mostly interested in the fur trade. The English, on the other side, wanted more and more land to settle in and make a profit from it. After many battles, the English started to change the situation and won the war after sounded victories in the Battle of Louisbourg and the Batlle of Quebec.
Arable land was one geographical feature all three colonial regions had in common. This was important because the soil was fertile and land was plentiful. This helped the colonies become profitable and big traders among other colonies.
