Answer:
Capitalization, use of ellipsis, and comma are the correct answer.
Step-by-step explanation:
In the first quotation, capitalization is the mistake because the quote expresses a complete sentence, so the first letter must be a capital, as in "The brave men..."
In the second one, the ellipsis is incorrect. An ellipsis consists in an omission indicated with a set of three dots (...) and it expresses a complete idea. In this case, the last idea is incomplete and makes its understanding difficult.
In the third one, the comma after finally is not necessary because the introduction phrase is short and it doesn't affect its understanding.
