Question
Which action is a way to reduce both air & noise pollution? aUse hand tools instead of power tools. bTurn down the volume of stereos & radios. cOpen windows & turn on fans. dAll of the above.
Solution
dAll of the above.
Explanation: a. Using hand tools instead of power tools can reduce both air and noise pollution. Power tools often run on gasoline or electricity, and their use can contribute to air pollution. They also tend to be noisy, contributing to noise pollution. b. Turning down the volume of stereos and radios can reduce noise pollution. c. Opening windows and turning on fans can reduce air pollution inside a home or building by increasing ventilation and reducing the concentration of pollutants. However, this action may not have a significant impact on outdoor air pollution.
