Which of the following contributed the most to the endurance of the English colonies in North America?

A) International treaties
B) Population
C) Military outposts
D) Government funding

The population of the English colonies played a crucial role in their endurance. As the colonies grew in size, they became more self-sufficient and were able to sustain themselves economically. Additionally, a larger population meant a larger workforce, which was necessary for the cultivation of crops and the development of other industries. Furthermore, the growth of the population made it easier for the English to defend their colonies against attacks from other European powers and Native American groups.
