Answer:
The English colonies weren't too far spread apart to not provide protection (arguably due to the Proclamation of 1763 which halted English expansion into America), was hospitable, provided ample land suitable for farming, and was along the coast to allow easy trade with the Caribbean or Europe. All these reasons helped them grow in population.
The reason Egypt and Nubia were interdependent, meaning that both countries had to rely on one another for certain resources that were needed, was because both countries needed each others help. Numbia had more trade routes than Egypt, had natural resources they were interested in, and could also help fight off any invaders of Egypt.
It depends do you want to be a strictly equine vet or all around large animal vet?
