Which one of the following pairs is mismatched ?

  1. Fossil fuel burning – release of CO2
  2. Nuclear power – radioactive wastes
  3. Biomass burning – release of CO2
  4. Solar energy – greenhouse effect

Answer

(4) Solar energy – greenhouse effect

Solution

Burning of fossil fuels and of biomass releases CO2, a greenhouse gas. ⇒ (1) and (3) are correctly matched.

Nuclear power plants produce radioactive wastes. ⇒ (2) is correctly matched.

Solar energy is a clean, non-polluting source; using it releases no greenhouse gas, so it does not cause the greenhouse effect.

∴ The mismatched pair is solar energy – greenhouse effect.

Answer: (4)
