Final answer:
It is true that American colonists developed an independent identity, especially post the French and Indian War. However, they were not completely self-sufficient in terms of consumer goods from Britain and the Conciliatory Proposition did not meet their demands. Colonists objected to how the tax money was applied, not the principle of taxation itself.
Step-by-step explanation:
The assertion that American colonists became very independent is true. Over time, the colonists developed a desire for autonomy, especially after events like the French and Indian War which fostered a common identity among them. However, the statement that most colonists in the eighteenth century were largely self-sufficient and did not need to import consumer goods from Britain is false. While some colonists were self-sufficient, many still relied on British goods and found themselves affected by British trade regulations.
The increasing sense of common identity and unity among the colonists indeed became one of the legacies of the French and Indian War, so that statement is also considered true. It contributed significantly to the eventual push towards independence.
Regarding the sentiments about taxation, the colonists' objection was not to the principle of taxation itself but to the fact that they had no representation regarding how the tax money would be spent. Hence, the statement that they objected to the application of tax money is true.
Lastly, the Conciliatory Proposition did not meet most of the American colonists' demands, and the colonizationist scheme was not widely popular among black abolitionists. Both statements are false.
