What book is this from than I can help
A because external means what is happening outside of you while all the others are internal which is what happens inside us emotionally.
Here is Benvolio's lines from the scene of Romeo and Juliet Part 2: Benvolio: I do but keep the peace: put up thy sword, Or manage it to part these men with me.The best paraphrase of Benvolio's lines would be this: I want to keep the peace, so put your sword away or use it to help me break up this brawl.Hope this answers the question.
