Read the passage below and determine which of the following statements can be logically inferred. Passage: To combat urban congestion and carbon emissions, a metropolitan council has implemented a "Green Transit Corridor" policy, offering significant tax rebates to logistics companies that replace their diesel fleets with autonomous electric delivery drones. Proponents suggest this will revolutionize last-mile delivery and revitalize the city's tech sector. However, labor unions express concern that the rapid automation of the delivery industry will bypass traditional job-security frameworks, leading to widespread displacement of courier drivers. Environmentalists, while supportive of the emissions reduction, have raised questions regarding the "noise pollution" and "sky clutter" caused by thousands of low-flying drones. Statements:
I. The primary goal of the "Green Transit Corridor" policy is to address both environmental and traffic-flow issues within the city.
II. Labor unions believe that the new policy will strengthen existing job-security frameworks for courier drivers.
III. The policy faces criticism or concern from multiple stakeholders regarding its social and environmental side effects.
