Answer to question 2
Answer and Explanation: Benjamin Franklin signed the Declaration of Independence due to his awareness that reconciliation was not possible with Britain. Prior to 1776, Franklin had worked to promote an easing of tensions between England and America but was increasingly aware that the divide between both was becoming insurmountable. In 1774, Franklin published the private letters of Colonial Governor Thomas Hutchenson to try and bring about a reunion.
