Answer:
2) Courage.
Explanation:
A connotation can be defined as the quality, feeling or an idea which a word brings to the mind of a person, as well as its literal, dictionary or primary meaning.
Courage refers to the quality that is being possessed by a confident or brave individual which makes him or her not to be intimidated, frightened easily while being cautious in his or her actions.
Hence, the word "courage" provides an appropriate connotation of the word heart as it is used in this sentence: The guard dog defended his owner with the heart of a warrior.
This ultimately implies that, the dog defended his owner courageously like a warrior.
The repitition of these words continue to enhance that something bad or abusive happened to a person, animal or living thing.
Bravery is something that cannot be taught; it just comes naturally and can somewhat be considered as an instinct. You will always encounter challenges which will bring out the brave soul in you.
For instance, you and your younger sister are left at home while your parents went out to buy some groceries. Unfortunately, it rained hard, a lightning struck and the lights came off. You are in the living room while your sister was left alone upstairs, crying. You know for yourself that you are afraid of the dark, but you need to be your sister's knight in shining armor.
Despite being scared, you set it aside and decided to be brave and go get your sister upstairs. Now that is just one of the many instances where bravery comes out. You might not notice it, but there are a lot of simple instances where you use your bravery to cope with the situation.
I believe the rhyme scheme would be ABAB.
Door rhymes with store and bell rhymes with tell.
