Why would an author choose a third-person narrator?

A third-person point of view can be omniscient, in which the narrator knows all of the thoughts and feelings of all of the characters in the story, or it can be limited. If it's limited, the narrator only relates his or her own thoughts, feelings, and knowledge of various situations and other characters.

hope this helps ;)

2#the answer is a

peace, morning, sun glooming, sorrow, woe pardon’d, punished, more hence, talk, story. all of these three words have to do something with a depressed, regretful tone. woe is another word for misery, heartache, so all of these words are about unhappy feelings.
