Question

amount of air pollution particles by state
use the graph to answer the following questions.
which state has the highest level of air pollution
particles for the year 2014?
which state shows the least change in air pollution
particles from 2006 to 2015?
what action is most likely to have helped reduce the
rate of air pollution particles?

Explanation:

• For the first question, we look at the value (y - axis) for each state in 2014 (x - axis). The state with the highest y - value in 2014 is Wyoming.
• For the second question, we calculate the difference between the y - values (air - pollution particle levels) in 2006 and 2015 for each state. The state with the smallest difference is Maryland.
• For the third question, common actions that reduce air - pollution particles include regulations on industrial emissions (e.g., setting limits on factory smoke emissions), promoting cleaner energy sources (like solar and wind energy instead of coal - fired power plants), and improving vehicle emission standards (e.g., mandating catalytic converters in cars).

Answer:

• The state with the highest level of air - pollution particles in 2014: Wyoming
• The state with the least change in air - pollution particles from 2006 to 2015: Maryland
• An action that likely helped reduce the rate of air - pollution particles: Implementing stricter industrial emission regulations (or promoting cleaner energy sources / improving vehicle emission standards)
