Final answer:
Thomas Paine's word choice of 'expires' in 'Common Sense' indicates that he views the separation between the American colonies and Britain as inevitable and final, much like the end of life.
Step-by-step explanation:
When Thomas Paine uses the word “expires” in the excerpt from Common Sense, he is conveying the idea that the connection or “kindred” between the American colonies and Great Britain is coming to an end. The use of this word suggests that Paine believed the bond between them was not just weakening but was on the verge of completely vanishing, akin to the end of life. This indicates that Paine foresaw the separation between the colonies and Britain as a natural and inevitable process, much like death is to life. He argues that the grievances and differences had become too significant, insinuating that the prospect of reconciliation was diminishing with each passing day, leading to the increasing possibility of American independence.
