Which question you want the answer
Answer:
The simile is my love is like to ice, and i to fire
I think first sentence and last two. The first one is appealing to a pet owner's feelings of wanting to be a good pet owner and the merchant is using that to persuade them to buy the biscuits. The last two sentences are appealing to a person's feelings of loneliness or being left out and using that to convince you to buy a pool. They both appeal to people's emotions in order to persuade them towards action, that's what it means to use pathos.
Literature, however, can be said to be the mirror of life, because it reflects and comments on aspects of things people encounter in their daily lives. Even futuristic novels such as The Hunger Games can reflect life, despite the fact that its world is alien to the modern human being.
