What should be included in the introduction of an essay for the test?

The introduction of an essay serves as a crucial foundation for effectively communicating the central argument and purpose of the piece. A strong thesis statement is essential because it clearly articulates the main argument the essay will explore. This statement not only provides a roadmap for the reader, indicating what to expect in the subsequent sections, but it also sets the tone for the entire essay. By outlining the main argument, the thesis statement helps to keep the writing focused and cohesive, guiding the reader through the points that support the writer's position.

Including a list of supporting facts, multiple quotations, or a summary of the conclusion in the introduction would detract from its primary purpose, which is to showcase the essay's central argument. Instead, these elements are typically reserved for the body paragraphs, where detailed analysis and evidence can be presented to back up the thesis.
