| LIST I | LIST II |
|---|---|
| A. Greenhouse gases | I. Snow Blindness |
| B. Electrostatic precipitator | II. Unleaded petrol |
| C. Catalytic converter | III. Thermal power plant |
| D. UV-B radiation | IV. Global warming |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → A-IV, B-III, C-II, D-I
(A) Greenhouse gases — this matches (IV) Global warming. CO2, methane and other greenhouse gases hold back the heat radiated from the earth and raise its average temperature.
(B) Electrostatic precipitator — this matches (III) Thermal power plant. It removes over 99 per cent of the particulate matter from the exhaust of thermal power plants.
(C) Catalytic converter — this matches (II) Unleaded petrol. Lead in petrol inactivates the catalyst, so vehicles with catalytic converters must use unleaded petrol.
(D) UV-B radiation — this matches (I) Snow Blindness. High doses of UV-B inflame the cornea, causing snow-blindness.
