Q. Consider the following:

1. Cigarette butts
2. Eyeglass lenses
3. Car tyres

How many of the above generally contain plastic?
Answer: All the three
Notes: All three items—cigarette butts (cellulose acetate), eyeglass lenses (often polycarbonate or CR-39), and car tyres (contain synthetic polymers such as styrene-butadiene rubber)—commonly contain plastics or plastic-derived polymers as significant components, making them contributors to plastic-based environmental pollution.
