Answer 2

2) The Olive Branch Petition begged Parliament to wait for an understanding to be achieved before acting on the colonists resistance.

The Olive Branch Petition was a document written by John Dickinson and adopted by the Second Continental Congress of the colonists in America on July 5, 1775, that was directed to the British King George.

The document explains why the colonists had been rebelling to the British government: they hadn't felt rewarded nor recognized after having won the French and Indian War (1754–63), they felt like they'd been punished instead: the government had enacted new laws and taxes waged on them.

However, despite all these events, the colonists claimed that they didn't want to enter in a war with the crown, all the opposite, and ask them to wait for an understanding to be achieved before acting on the colonists' resistance.
