Final answer:
A supporting text in a case study offers additional context and evidence, crucial for reinforcing the main points, and typically includes an opening and concluding paragraph, quotes, and body paragraphs with topic sentences and detailed support.
Step-by-step explanation:
A supporting text within a case study provides additional evidence and context that helps to strengthen the main points of the study. Whether it is the opening paragraph, which sets the stage with background and historical context, or the concluding paragraph, which ties everything together, both sections are integral to presenting a cohesive argument. Additionally, quotes that serve as authoritative evidence can bolster the case study's claims and credibility.
Body paragraphs of a case study are particularly crucial because they contain the main points supported by evidence and analysis. This evidence may come in various forms, such as facts, statistics, or expert opinions, and is usually presented in formal language according to the conventions of the discipline's formatting guide—like the APA format in this context.
Notably, while a paragraph typically begins with a topic sentence that reflects the argument of the thesis statement, it is crucial to support the argument with relevant quotes and data and provide explanations and significance for that supporting evidence. This not only reinforces the argument but also aids the reader in understanding its importance within the context of the case study.
