Final answer:
The statement that colonists did not necessarily oppose the principle of taxation, but rather the application of tax money, is True. They wanted representation in tax decisions. The claim that most colonists were self-sufficient and did not need to import goods is False.
Step-by-step explanation:
The True or False statement in question pertains to the sentiment of colonists towards the principle of taxation. It's True that the colonists did not necessarily object to the principle of taxation itself but took issue with how the tax money would be applied, particularly without their consent or representation in the British Parliament.
This sentiment was encapsulated in the famous phrase "No taxation without representation". The colonists wanted to have a say in how their taxes were used and didn't oppose the idea of taxation as a general principle.
As for the second statement regarding the self-sufficiency of the colonists and their need to import consumer goods from Britain, it is False. Many colonists were not completely self-sufficient and relied on imported goods from Britain for items they could not produce locally.
