Step-by-step explanation:
The statement that best summarizes the following portion of the Declaration of Independence is: "Sometimes nations must separate from one another."
In this portion of the Declaration of Independence, the author is stating that under certain circumstances, it may be necessary for one people to dissolve their political ties with another people and become a separate, independent nation. The author goes on to say that it is important to explain the reasons for this separation to the rest of the world.
This passage does not suggest that nature provides certain privileges to some nations or that nations should remain separate and equal from one another. It simply acknowledges that there are times when it may be necessary for nations to separate from one another and that it is important to explain the reasons for doing so. Therefore, the statement that best summarizes this portion of the Declaration of Independence is "Sometimes nations must separate from one another."
