In the question below, a passage is given followed by three statements. You must determine which combination of the statements SUPPORTS the case for the proposed policy. Argument: To address the mounting waste crisis, a city council proposes a "Zero-Waste Mandate" that bans all single-use plastic packaging for food and beverages. They plan to replace them with a city-wide system of reusable, standardized containers that are washed and redistributed. Proponents argue this will eliminate landfill waste and lower long-term costs for businesses. Critics argue that the move will increase water usage for washing and create hygiene risks and operational burdens for small vendors. Which of the following statements, if true, would SUPPORT the case for the Zero-Waste Mandate?
I. Long-term environmental studies show that the carbon and water footprint of a single reusable container becomes lower than that of disposable plastics after only 15 uses.
II. Data from cities with similar mandates show that "Standardized Washing Hubs" created high-efficiency jobs and reduced individual vendor overhead by 20%.
III. Public health reports confirmed that industrial-grade sanitization in centralized hubs consistently exceeds the hygiene standards of traditional disposable packaging.
