Question

Why did Parliament believe the colonists would accept the Tea Act of 1773?

Answer 1

The correct answer here is the option E.

The British Government thought that their increase of taxes would be accepted as they have lowered the the price of tea in the colonies and that the colonies would be grateful for a chance to get tea at the cheaper price. This as we all know did not work out and resulted in the Boston Tea Party  where the colonists threw large amounts of tea into the water as a sign of protest.
