Ques:3 Which of the following is not a limitation of the effectiveness of smog towers as a solution to urban air pollution? (a) Smog towers are energy-intensive and require significant operational costs for continuous functioning. (b) They primarily address particulate matter but are less effective against gaseous pollutants like nitrogen oxides and sulphur dioxide. (c) The scalability of smog towers is restricted due to their limited range and localized impact. (d) Smog towers are designed to operate only in specific weather conditions, such as high wind speeds. Correct Answer Answer: d Explanation: While options a, b, and c represent the limitation of using smog tower as a solution to urban air pollution, Option d is not correct statement. Smog towers are not designed to depend on specific weather conditions like high wind speeds; instead, they use mechanical systems to draw in air for purification. The overall effectiveness of smog towers remains limited due to cost, scalability, and their inability to tackle gaseous pollutants comprehensively. Hence option a, b, and c are limitations of smog tower. Option d is not correct. Hence option d is correct answer. Source: Indian Express (page 19)
