Question

what happened as a result of the treaty of paris?
spain, the predominant colonial power from 1500 to 1650, was officially forced out of north america.
the british won the fight over the fertile ohio river valley and gained control of most french lands in north america.
the prussians gained control of portugal and eastern europe by 1800.
the british became the dominant colonial power in the americas by 1800.

Explanation:

This refers to the 1763 Treaty of Paris ending the French and Indian War. It transferred most French North American territories to Britain, including the Ohio River Valley, while Spain (not forced out) gained Louisiana, and the other options are factually incorrect: Prussia was not involved in this treaty, and Britain's dominance in the Americas by 1800 is not the direct result of this specific treaty.

Answer:

The British won the fight over the fertile Ohio River Valley and gained control of most French lands in North America.
