Which stressor is described as affecting products and structures, damaging a society's goods and services?

• A. Noise and litter affect quality of life.
• B. Global warming interferes with ecological balance.
• C. Lead poisoning and air pollution.
• D. Effects of air pollution on products and structures damage society's goods and services.

Answer: (D)

The stressor tested here is the impact of air pollution on materials and built objects. Air pollutants like sulfur dioxide, nitrogen oxides, ozone, and particulate matter interact with surfaces and materials—causing corrosion, staining, embrittlement, and accelerated weathering. Metals, stone, concrete, textiles, and other goods deteriorate faster, reducing product quality and shortening the lifespan of infrastructure and equipment. That degradation translates into higher maintenance and replacement costs and can disrupt the delivery of goods and services, harming the economy as a whole.

Other options describe different effects: noise and litter mainly affect quality of life; global warming more broadly disrupts ecological balance; lead poisoning and air pollution highlight health and environmental hazards but don’t specifically emphasize damage to products and structures that supply goods and services.
