Final answer:
Shanika uses the emotional appeal, or pathos, to create information hunger in her audience regarding child abuse, aiming to elicit sympathy and concern.
Step-by-step explanation:
Shanika is appealing to the emotional needs of her audience, specifically their sense of empathy and concern for children's wellbeing. By discussing the importance of positive messages and the damaging effects of verbal and emotional abuse on self-esteem, she is using pathos to create information hunger. Pathos appeals to the audience's feelings, which in this case would be sympathy for children who suffer from abuse and a desire to learn more about how to prevent it. The goal is to compel the audience to care about the issue on an emotional level, thereby increasing their interest in Shanika's speech on child abuse.
