Answer:
Quotation 1 contains a capitalization error.
Quotation 2 wrongly uses 'ellipses.'
Quotation 3 makes incorrect use of a comma.
Explanation:
The first quotation communicates a complete sentence and therefore, the first letter must be capitalized('The brave men') to make it grammatically correct.
In the second quotation, ellipses have been used incorrectly. It is a punctuation mark consisting of three periods('...') to indicate the omission of a word or phrase that can be inferred from the text. It communicates a complete idea but in this quotation, the idea is not completed after 'nation...' and therefore, the readers are not able to understand it.
The last quotation employs comma inappropriately succeeding the word 'finally' as the sentence is quite short and the use of comma unnecessarily breaks its meaning. There is no need for a comma here as the meaning is more clear and precise without using it.
