Question

What was Lord Grenville's plan to enforce new taxes?
1. Requiring British troops to be fed and housed by colonists.
2. The British didn't allow the colonists to settle the Ohio River Valley.
3. The British closed the Boston port to keep them from trading.
4. The British started the Boston Massacre to frighten the colonists.

Answer 1

The British started the Boston Massacre with a few shots into a crowd to scare them. This started because the people were opposed to new taxes.

Answer 2

I believe the answer is: 2. . The British didn't allow the colonists to settle the Ohio River Valley.

At that time, the British's government influence was really weak across the ohio River valley due to the presence of both the French empire and the native americans. If the colonists settle on that territory, British wouldn't be able to impose the new taxation rules.
