Final Answer:
The pair of vocabulary closely related in meaning as they are used in the excerpt from Jefferson Davis’s Inaugural Speech is "sovereignty" and "independence."
Step-by-step explanation:
Sovereignty: Refers to supreme authority or power held by a state or entity to govern itself without external interference. In the context of Jefferson Davis's speech, "sovereignty" likely pertains to the autonomy and self-governing rights sought by the Confederacy.
Independence: Denotes freedom or autonomy from control, influence, or reliance on others. In the context of Davis's speech, "independence" aligns with the desire of the Confederacy to break away from the Union and establish its self-rule.
Jefferson Davis's Inaugural Speech as the President of the Confederate States of America likely emphasizes the concepts of sovereignty (asserting self-governing authority) and independence (breaking away from external control) in relation to the Confederacy's aspirations.
