In the passage about upgrading a sustainable city with clean energy and less waste, match each old polluting feature to a new sustainable feature (word bank: Solar Panel Farm, Bike Lanes, Recycling Center, Wind Turbines, Electric Buses): 1) Coal Power Plant 2) Gas-powered City Buses 3) Huge City Landfill 4) No space for bicycles on the road.

What you are matching in this sustainable city upgrade

Each “old” feature causes pollution (smoke, exhaust, or waste buildup), and each “new” feature is meant to cut pollution by switching to clean energy, cleaner transport, or reducing trash.

Match each polluting feature to the best replacement

1. Coal Power Plant: it makes electricity but creates smoke, so replace it with a clean electricity source, Wind Turbines.
2. Gas-powered City Buses: they release exhaust, so replace them with Electric Buses, which do not have tailpipe emissions.
3. Huge City Landfill: it is a big garbage dump, so replace it with a Recycling Center to reduce waste going into the ground.
4. No space for bicycles on the road: add Bike Lanes so people can bike safely instead of driving.

Why one word bank option is left over

Both Solar Panel Farm and Wind Turbines are clean energy options, but only one is needed to replace the single coal power plant in this matching set, so the extra clean energy choice remains unused.
