Question

select the correct answer.
which of these peoples behavior is most helpful for reducing air pollution?
a. alec and his wife always reuse their grocery bags and donate old clothes to charity.
b. kristy and her coworkers began carpooling to work instead of taking individual cars.
c. rebecca and her family take their used batteries to a special waste disposal site.

Explanation:

To reduce air pollution, we focus on reducing emissions from vehicles. Carpooling (option B) reduces the number of cars on the road, thus cutting down vehicle - related air pollutants. Reusing bags and donating clothes (option A) is about waste reduction and not directly air pollution. Disposing of batteries properly (option C) is about hazardous waste management, not air pollution reduction.

Answer:

B. Kristy and her coworkers began carpooling to work instead of taking individual cars.
