Answer:
The answer to your question would be the following one: The United States Declaration of Independence states: "We hold these truths to be self-evident: That all men are created equal."
Step-by-step explanation:
The error in verb-tense consistency is found in the verb "stated". It should be in the present tense for all the clause to follow the same tense. Verb-consistency refers to keeping the same verb tense throughout a whole clause. If you want to have two or more time periods in a clause, you should start a new clause or a new sentence. In the sentence above, all the verbs in the quotation are in the present tense, so "stated" should also be in that verb tense.
