What term means to provoke and urge on?

The correct answer is "Incite." This term specifically refers to the act of provoking or urging someone to take action, often in a way that encourages them to behave aggressively or to engage in a particular behavior. It carries a connotation of stirring up emotions or motivations within individuals or groups, leading them to respond in a specific manner.

For example, someone might incite a crowd to protest or take a stand on an issue, showing how the term is associated with motivating or inflaming actions. The use of "incite" is prevalent in contexts where someone's influence or encouragement has a significant impact on others' behavior.

The other terms provided do not carry the same meaning. "Impulse" refers to a sudden desire or urge, but it does not specifically imply that someone is urging another person on. "Ingratiate" means to gain favor by flattering or trying to please someone, which does not fit the context of provoking action. "Initiate" generally means to start or commence something, lacking the connotation of provocation implied in "incite." Therefore, "incite" is the term that most accurately describes the act of urging or provoking action.
