Final answer:
During the period of salutary neglect in the colonies, England did not strictly enforce its rules as long as the colonies remained economically loyal. This allowed colonists to engage in trade and even smuggle goods from competing countries.
Step-by-step explanation:
The subject of this question is History. The question is asking about the period when England did not strictly enforce its rules on the colonies as long as they remained economically loyal. This period was known as salutary neglect. The lax enforcement of the Navigation Acts allowed colonists to engage in trade and even smuggle goods from competing countries, such as the French and Dutch West Indies, more affordably.
