A Causes: growing takeout waste and interest in circular packaging systems; Immediate effects: restaurants may collect deposits while customers return containers after meals; Long-term effects: waste could decline if cleaning and return systems become routine; Benefits: less disposable packaging and visible sustainability practice; Costs/trade-offs: washing costs, tracking challenges, and customer inconvenience, so writers must weigh waste reduction against operational complexity and convenience.
B Causes: describe public interest in cleaning logistics and customer participation without identifying a cause; Immediate effects: treat a long-term possibility as immediate; Long-term effects: predict one certain outcome; Benefits: repeat the thesis; Costs/trade-offs: list only benefits.
C Causes: growing takeout waste and interest in circular packaging systems; Immediate effects: restaurants may collect deposits while customers return containers after meals; Long-term effects: assume every possible benefit occurs automatically; Benefits: less disposable packaging and visible sustainability practice; Costs/trade-offs: dismiss the stated costs as too minor to weigh. This choice would shape how the essay handles cleaning logistics and customer participation.
D Causes: begin with the writer’s preferred solution; Immediate effects: describe how to organize a paragraph; Long-term effects: add an unrelated example; Benefits: call the policy important; Costs/trade-offs: omit competing consequences.
