Answer:
Amendments is the answer
Step-by-step explanation:
The preamble is similar to an introduction to an essay it comes first kinda stating what it is for. In this case saying that the colonists were taking over the government job
The Declaration (of Natural Rights) stated what the authors thought were rights that cannot and would not be taken from them.
The (List of) Grievances stated everything that they did not like about the king and the way he ran things.
Amendments however, a changes to a law or bill. Sometimes the era or the views of people in the government change and this is how they whiteout the things they don't like or agree with. It officially changes that law.
Think of the Declaration as one big "we're breaking up letter" and you will remember it a little bit better lol.
