The tone in the last stanza is regretful. The poem is about a man who received advice from a wise man that he can give away all his wealth but not his heart. He's told that once you give away your heart, you lose it and end up regretting it. He experiences it and regrets afterwards.
The correct answer is:
The voice affects consistency of tone and the amount of bias revealed.
Explanation:
Voice, in literature, is what we hear when we read the work of a specific author, it is created by the format of the author's writing, while in a spoken language it would be the sound of the voice.
Tone, on the other hand, is the attitude and feelings of the author towards the writing, and it is reflected in the choice of words of the writer to express those feelings to the audience, in a spoken language it would be the actual tone of the voice when someone speaks. Voice affects consistency in tone and the amount of bias revealed because the format used to write a suspense novel, or an ironic comedy would change to express the actual purpose of the writing.
