Which of the following best describes a reason why england wanted to establish colonies in north america?
a. to gain raw materials such as crops
b. to prevent france from forming a colony
c. to find a river route across the continent
d. to fight for territory with spanish colonists

The reason why England wanted to establish colonies in North America were numerous. It surely was because of their rivalry with Spain (who at the time already had established many colonies and benefited because of that immensely) but it was also because they were rivals (not openly) with France as well, having colonies for that reason would give them an advantage. What is also true is that by establishing new colonies, they could gain new materials such as crops, but more importantly wood and other possible precious metals.

So in essence, A, B, and also D could be considered correct here in my opinion. With D perhaps being most likely.
