Answer: The right answer is the A) War leaves enduring scars.
Explanation: In the excerpt from this old English poem, the speaker, a shield, is specifically describing its difficult "existence" - an existence of loneliness, sacrifice, courage, hopelessness and lack of recognition. Its wounds are many, and permanent, and they do not heal. It is constantly fighting and is not granted any care, so it never recovers. Much like the shield, those who fight in a war have scars that remain for the rest of their lives.
