Where should an author include evidence to support their claim?

Conclusion
Body Paragraph(s)
Thesis Statement
Introduction

An author should include evidence to support their claim in the body paragraph(s) of their work. The introduction typically provides an overview of the topic and introduces the thesis statement, while the thesis statement presents the main argument or claim. The conclusion typically summarizes the main points and restates the thesis. While the introduction and conclusion may reference or briefly summarize the evidence, the majority of the supporting evidence should be included in the body paragraph(s) to effectively strengthen the author's claim.
