What types of fishing activities contribute most to the plastic in the GPGP?

• Trawlers, fixed gear, and drifting longlines

• Recreational fishing

• Coastal net fishing

• Deep-sea explorations

What is the primary material of the thick, positively buoyant plastics found in the GPGP?

• Rubber and latex

• Nylon and polyester

• PVC and polystyrene

• Polyethylene and polypropylene

According to the study, why is plastic from fishing activities more likely to reach the GPGP than plastics from rivers?

• It is biodegradable

• It is lighter and floats better

• It is predominantly metallic

• It spends less time near coastlines

What does the presence of old and diverse plastic items in the GPGP indicate about the pollution?

• It is effectively being cleaned up

• It is mainly from nearby sources

• It is recently deposited

• It persists and degrades into microplastics
