To know if an introduction is flawless, you need to look for 3 things in it; a hook, background information, and an effective thesis statement. A hook should be written in a way that it grabs the reader's attention. For writing a hook, you can write a thought-provoking question, an interesting fact, or a relevant anecdote. Also, avoid cliches when writing a book. Next, in the background information, include all the relevant information that is required by readers to make sense of the topic. Here, you have to add all the context and provide the definition of keyterms. Next, for the thesis statement, make sure that it states the main argument of your essay and is focused. Moreover, you can also hire essay help in London to assist you in crafting an introduction.
