Final answer:
The Currency Act of 1751 prohibited the use of paper money in the colonies and gave Parliament control over the colonial currency system.
Step-by-step explanation:
The Currency Act of 1751 was a legislative measure passed by the British Parliament that gave Parliament control over the colonial currency system. It stated that no paper bills or bills of credit would be considered legal tender for payment of any debts or obligations. This act effectively made paper money illegal to use in the colonies and put the colonists at a further economic disadvantage in their trade relations with British merchants.
