Which term describes a continuous effect from a product?

• A. Conductivity
• B. Ripple effect
• C. Life-cycle analysis
• D. Ecodesign

Answer: (B)

The idea being tested is about ongoing, indirect consequences that spread beyond how a product is used. That continuous spread of effects is described as the ripple effect. It captures how a product can create secondary and tertiary impacts that propagate through systems—like environmental, economic, or social changes that continue after the product is in the hands of users.

Why this fits best: a ripple effect focuses on those cascading outcomes that extend beyond the product’s immediate function, which is exactly what “continuous effect from a product” implies. The other terms don’t describe this spreading, ongoing impact. Conductivity is a property of how well a material conducts electricity or heat. Life-cycle analysis is a method for assessing a product’s environmental impacts across its entire life, not the ongoing propagation of effects. Ecodesign is a design approach aimed at reducing environmental impact, not the phenomenon of continuing consequences.
