What is a main reason that the alliance between Ousamequin’s people and the people of Plymouth ended?

D. The settlers insisted on sharing the land.

Explanation:

As time passed, tens of thousands of settlers from New England came into the colony and so they had to expand the land where they settled. What caused a strain in the alliance with Native Indians was the fact that the English people wanted the Natives to give up their land for them.

To solve the problem they bought a large expanse of land from the Sachem or Massosoit who was the leader of the natives to accommodate their growing population. The expanse of land was about fourteen miles square.
