Final answer:
The statement about colonial cities being planned as export centers for raw material going to Europe is true, reflecting the mercantilist system's aim during the colonial period. The claim that most settlers in eighteenth-century North America were self-sufficient and did not need to import goods from Britain is false, as colonial economies were closely tied to the mother country for manufactured goods.
Step-by-step explanation:
The statement, "Colonial cities were planned as export centers for raw material going to Europe," is true. During the era of mercantilism, the primary economic purpose of colonies was to produce and supply raw materials to the mother country, supporting its industrial growth. European powers, such as Britain and France, established colonies that were designed to facilitate the extraction of raw materials. Infrastructure such as port cities and transportation systems were often developed with the specific intention of optimizing the export of resources like cotton, tobacco, and sugar to Europe.
The assertion that "Most colonists in eighteenth century North America were largely self-sufficient, so they did not need to import consumer goods from Britain" is false. Despite some degree of local production and self-sufficiency, colonial economies were structured to complement the industrial mother country. As such, colonies generally imported finished goods and consumer products from Europe while focusing their own economies on the export of raw materials.
