I don't know 6 but 5 it's the American flag
The correct answer to this open question is the following.
What were the causes of the American Revolution? Explain the initial goals of the colonists in 1765 at the time of the Stamp Act and the evolution of their ultimate decision to declare independence in 1776.
The initial causes of the Revolutionary War of Independence were the following. The American colonists were sick and tired of the unfair laws and legislation imposed by the British government. Colonists were tired of the heavy taxation imposed by the English monarchy such as the Navigation Acts, the Stamp Act, the Townshend Act, or the Tea Act, among many others.
The ultimate decision came when these colonists were angry and upset about the fact that they had no voice or representation in the British Parliament. Colonists knew that by then, they were capable of establishing their own form of government.
Pamphlets such as Thomas Pain's "Common Sense" invited Patriots to support the Revolutionary War. And so it was.
The war started and prominent colonists such as Thomas Jefferson, Robert Livingston, Benjamin Franklin, Roger Sherman, and John Adams drafted the Declaration of Independence that was promulgated on July 4, 1776.

I'd say the correct answer is C. fur trade.
As you already know, Russia is famous for its fur, especially given the temperatures in that country. Fur is important for Russians because they have to warm themselves one way or another. So they obviously wanted to expand into territories where they could continue that trade.
