Actually, I didn't answer the first question that year, but I chose C...a, which should be ruled out from the beginning. This is an interference option. You don't think Britain is oppressing and plundering that colony, but why can't other places unite? Let's talk about C. Enlightenment thought is "calling for rational sunshine to dispel the darkness of reality, criticizing absolutism and religionism, and calling for the pursuit of political democracy, equal rights and individual freedom". Essentially, it is the ideological liberation of the bourgeoisie. If capitalism in North America is underdeveloped, this idea will be difficult to circulate. Let's talk about B first, the positive development of capitalism will promote the development of productive forces, thus gaining certain strength; The development of capitalist economy will need a unified market, but Britain does not agree. Not to give North America a unified market, but to suppress the price in North America, trying to use it as their eternal source of raw materials. Where there is oppression, there will naturally be resistance, and people with common interests and needs will naturally unite.

The second question, the biggest difference between the two options is in the object and time. The object of A is the North American people, and the object of B is the British colonists. Only B can break up ... Secondly, 1776, the people of North America have resisted the British colonization. At this time, the people of North America need independence, which is the fruit of victory after armed resistance.

In fact, the third question should not be stubborn. Just read "number one" clearly. The shooting in Lexington is only a follow-up. His main body is not a "farmer" but a militia.

I hope I can help you.
