Thomas Paine (1737–1809) was a radical writer who emigrated from England to America in 1774. Just two years later, early in 1776, Paine published Common Sense, a hugely influential pamphlet that convinced many American colonists that the time had finally come to break away from British rule. In Common Sense, Paine made a persuasive and passionate argument to the colonists that the cause of independence was just and urgent. The first prominent pamphleteer to advocate a complete break with England, Paine successfully convinced a great many Americans who'd previously thought of themselves as loyal, if disgruntled, subjects of the king.

The churchill speech was considered important because the speech was given when there was critical time in the history of the world.
Churchill speeches were being met with criticism which was from public of Britain and in the United States it was received in a better way.
Churchill believed that a speech can be powerful if vivid pictures and sound waves which bring about rapid succession.
Some of his speeches he said that he will fight on beaches, never despair. He told his people never despair despite what comes on their way.
I believe it is C, Great Britain. On July 1, 1867, with passage of the British North America Act, the Dominion of Canada was officially established as a self-governing entity within the British Empire. I hope this helped, have an amazing day :)<span />
