The purpose of a hook in an introductory paragraph is to grab the reader's attention and entice them to continue reading. It aims to make the reader curious about the topic or story being discussed and sets the tone for the rest of the essay or article. The hook can be a quote, a surprising fact, a thought-provoking question, or an engaging anecdote. Its primary objective is to make the reader interested in what is to follow and create a desire to learn more.
