Answer: False
Explanation:
It is not essential to introduce ALL the supporting evidence in the introduction of an argumentative essay.
In most argumentative and research essays, it is best to provide an introduction that introduces the topic, presents the main ideas or argument of the essay, and provides a foundation of knowledge for the reader. In some cases, this may include introducing some evidence or data that support the main points of the essay. However, it is not essential to include ALL of the supporting evidence in the introduction, as this may be covered later in the body paragraphs of the essay, where it is more suitable and in depth.
