Answer:
An introduction has one main topic. There are often subtopics within the main topic, but there is only one main idea.
An introduction can include any of the following elements:
* A thesis statement that introduces the main point or argument of the essay.
* A hook to catch readers' attention and draw them into reading further.
* The background information about the topic. This may be used to explain why this topic is important for people to know more about.
* Any necessary definitions. For example, if you're writing a science-related article, it's essential to define technical terms.
* The outline of your paper. If you've written an informative paper, you might want to use a chart to organize your ideas.
