Final answer:
The policies, including the Navigation Acts, were designed to help Great Britain raise revenues and exert control over colonial trade as part of its mercantilist strategy, which eventually led to colonial discontent.
Step-by-step explanation:
The main goal of the policies illustrated was to enable Great Britain to raise revenues and control trade. The British imperial system used the theory of mercantilism to benefit the mother country economically and politically. With the passage of measures such as the Navigation Acts, Britain aimed to create a favorable balance of trade, where colonies would provide raw materials at low costs and purchase higher-priced manufactured goods from the mother country.
This system also involved greater political oversight over colonial commerce. While this did increase the standard of living for many colonists and provided protection by the Royal Navy, it led to growing discontent and claims for political rights, planting the seeds for future resistance.
