This question is about the "declaration of independence"
Answer and Explanation:
The main premise that Jefferson argues is that American colonies should be independent of British rule, which established a tyrannical, oppressive and exploitative government, preventing America from being as big and important as it could be.
Jefferson supported his argument with very well-structured evidence based on facts that confirmed everything he said about the tyranny of the British monarchy and America's failed attempts to live in peace with the English domination, with that, we can say that Jefferson did whatever was at hand to establish the truth of the premise to which he was positioning himself.
