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:

• Option A: Reusing grocery bags and donating old clothes helps with waste reduction and resource conservation but has a more direct impact on solid waste management rather than air pollution reduction.
• Option B: Carpooling reduces the number of vehicles on the road. Fewer vehicles mean less fuel consumption and fewer emissions (such as carbon monoxide, nitrogen oxides, and particulate matter) from vehicle exhausts, which directly helps in reducing air pollution.
• Option C: Taking used batteries to a special waste - disposal site is important for preventing soil and water pollution (as batteries contain hazardous materials like lead, mercury), but it is not directly related to air pollution reduction.

Answer:

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