• False (Decibels measure sound intensity, not pollution levels.)

Non-point-source pollution can be traced to one specific source.

• False (Non-point-source pollution comes from multiple, diffuse sources and isn't traceable to a single point.)

Point-source pollution is pollution that comes from identifiable locations.

• True (Point-source pollution originates from specific, identifiable sources, such as factories or wastewater treatment plants.)

Burning fossil fuels releases too much carbon dioxide into the atmosphere.
