Exhibit: An electronics retailer is deciding which category to mark down online first. Source 1: Inventory tab: earbuds have 8.4 weeks of supply, monitors have 5.9, and keyboards have 9.1. Source 2: Sell-through tab: earbuds sell through at 11% weekly, monitors at 18%, and keyboards at 9%. Source 3: Markdown rule: prioritize categories with more than 8 weeks of supply and sell-through below 12% weekly. Which inference is consistent with all sources?
