My professor expects a tight case study argument—what template can keep the structure clear and persuasive?

We need to produce a concise English reply, 120-200 words, 1-2 tight prose paragraphs. Open directly with the useful answer, no greeting, no restatement, no filler. Give the single most helpful concrete piece of advice, then one supporting reason. Use contractions and natural phrasing. May include ONE brief hypothetical example (a plausible student scenario) to illustrate, just weave it in. Do not invent real names, statistics, institutions, laws, or citations. No advertising, no external service names. No headings, lists, bold, labels, or Markdown. End with a complete, useful sentence. We need to give a template for case study argument: maybe "Problem–Evidence–Implication" or "Situation–Complication–Resolution–Evaluation" or "IRAC" (Issue, Rule, Application, Conclusion) but for case study. Provide single most helpful concrete piece of advice: use the "Claim–Evidence–Warrant" structure repeated for each sub-argument. Then supporting reason: it forces logical linkage and keeps persuasive flow. Then give a brief hypothetical example: e.g., a student analyzing a marketing failure, using claim-evidence-warrant for each point. End with a complete useful sentence. Word count: 120-200 words. Let's aim ~150 words. Two paragraphs. Paragraph 1: start with advice: "Use a claim‑evidence‑warrant (CEW) loop for each argumentative move." Then supporting reason: "It makes you state what you’re asserting, show the data that backs it, and explain why that data matters, which naturally links evidence to your thesis." Then maybe mention you can outline sections: intro, background, then series of CEW blocks, then conclusion. Paragraph 2: give hypothetical example: e.g., "Imagine you’re arguing that a company’s supply‑chain redesign caused a drop in customer satisfaction; you open each block with a claim like 'The redesign increased lead times,' then cite the survey data showing a 15% rise in complaints, and warrant by explaining how longer lead times erode trust." Then end with a complete useful sentence: maybe "By consistently applying this pattern, you’ll keep your 3,000‑word case study tight, persuasive, and easy to follow within your deadline." Check for any prohibited content: no real names, stats, institutions. The example uses generic data like "15% rise in complaints" – that's a statistic; is that allowed? The instruction says "Do not invent real names, real statistics, institutions, laws, or citations." So we must avoid inventing statistics. So we cannot give a specific percentage. We need to avoid invented stats. So we need to phrase example without specific numbers. Use vague language like "the survey showed a noticeable increase in complaints" or "the data indicated a rise". Avoid exact numbers. Make sure not to mention any external service. No headings, no lists. Word count: Let's craft ~150 words. Paragraph 1: maybe 80 words. Paragraph 2: 70 words. Let's draft: "Use a claim‑evidence‑warrant loop for each point you want to make. Start with a clear claim that ties back to your overall thesis, then present the specific piece of evidence from your case that supports it, and finally explain the warrant – the reasoning that shows why that evidence matters for your claim. This pattern forces you to link every datum directly to your argument, preventing stray description and keeping the narrative persuasive." Paragraph 2: hypothetical example: "For instance, if you argue that a firm’s new pricing strategy hurt brand loyalty, you could open a block with the claim 'The price increase alienated long‑term customers,' follow with the evidence 'customer interviews revealed
