Final answer:
The excerpt from the Declaration of Independence states that it is necessary to dissolve the political bands connecting one group of people with another and declare the causes for doing so. The main topic is the purpose and principles of the Declaration of Independence.
Step-by-step explanation:
The excerpt from the Declaration of Independence states: 'When in the course of human events it becomes necessary for one people to dissolve the political bands which have connected them with another, and to assume among the powers of the earth.
The separate and equal station to which the laws of Nature's God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to c. dissolve, Government.'
This means that when it is necessary for a group of people to separate themselves from another and stand on their own, it is important to explain the reasons for doing so.
The excerpt then goes on to state the core beliefs of the Declaration of Independence, including the idea that all men are created equal and have certain unalienable rights.
