An effective introduction includes (choose all that apply):

Background information that gives the outline of the essay

A thesis statement that occurs at the beginning of the introductory paragraph

An effective introduction may include:

- Background information that gives the outline of the essay: This helps set the context and provides a brief overview of what the essay will discuss.
- A thesis statement that occurs at the end of the introductory paragraph and states the main points of the essay: The thesis statement serves as a clear and concise summary of the main argument or purpose of the essay. It typically comes at the end of the introduction to guide the reader's understanding of the essay's focus.

Background information that tells the reader everything about the topic of the essay is not typically included in the introduction. Instead, it is spread throughout the body paragraphs to support and develop the thesis statement. Additionally, a thesis statement that occurs at the beginning of the introductory paragraph is less common, as it may leave the reader confused without any prior context or information.

An effective introduction includes:

1. Background information that gives an overview of the topic: This is one option for an effective introduction. It provides context and helps the reader understand the subject matter. However, it is important to note that this background information should not be an exhaustive explanation of the topic, but rather a concise summary.

2. Background information that gives the outline of the essay: This is another option for an effective introduction. Instead of providing a broad overview of the topic, this approach involves giving a preview of the essay's structure. It briefly outlines the main points or arguments that will be addressed in the essay.

3. A thesis statement that occurs at the end of the introductory paragraph and states the main points of the essay: This is a key element of an effective introduction. The thesis statement provides a clear and focused statement of the main argument or purpose of the essay. It typically comes at the end of the introduction and serves as a roadmap for the rest of the essay.

4. A thesis statement that occurs at the beginning of the introductory paragraph: While it is more common for a thesis statement to be placed at the end of the introduction, there are instances where it can be placed at the beginning. However, this approach is less common and may depend on the specific requirements or preferences of the essay assignment.

To sum up, an effective introduction can include either background information about the topic or an outline of the essay, alongside a clear and focused thesis statement. The position of the thesis statement within the introduction may vary, but it is typically placed at the end.
