Could I get some help please and thank you?!

How could a city reduce its air pollution?

A improve its public transportation system

B eliminate the dumping of all solid waste

C eliminate runoff from chemicals used at the airport

D require all cars use gasoline with lead
I think it is B

There's only one of those choices that would help make the AIR cleaner, but it's not B. That choice has to do with the earth, not the air.

Please re-think.

To determine how a city could reduce its air pollution, we need to consider the options provided and identify the most viable solution. Let's analyze each option:

A) Improve its public transportation system: This option could help reduce air pollution since it would encourage more people to use public transportation instead of private vehicles. By decreasing the number of cars on the roads, there would be less emissions, thereby reducing air pollution.

B) Eliminate the dumping of all solid waste: While proper waste management can contribute to overall environmental health, this option specifically targets solid waste and may not have a direct impact on air pollution reduction. However, it is still an important step for overall environmental sustainability.

C) Eliminate runoff from chemicals used at the airport: This option addresses a specific source of pollution, but it doesn't encompass all sources of air pollution within a city. While important for airports, it may not have a significant impact on air quality citywide.

D) Require all cars to use gasoline with lead: This option would actually worsen air pollution, as leaded gasoline emits harmful pollutants. Therefore, it is not a suitable solution for reducing air pollution.

Based on the analysis, option A (improving the public transportation system) seems to be the most effective in reducing air pollution, as it directly addresses the main source of emissions - private vehicles. However, it is crucial to note that a comprehensive approach involving multiple strategies is usually required to significantly reduce air pollution in a city.
