Read the following passage about The 2023 Air Quality Crisis and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 23 to 30.
During summer 2023, North American air quality faced a serious crisis when Canadian wildfires burned over forty million acres of forest. These huge fires forced thousands to leave their homes while creating enormous smoke clouds that moved southward across national borders. The resulting air pollution affected millions of Americans, especially those living in northeastern and midwestern regions. This environmental disaster showed how natural disasters can quickly spread beyond one country's borders.
After twenty years of steady improvements, America's air quality suddenly got worse throughout 2023. Fine particulate matter (PM₂.₅) levels reached heights not seen since 2007, while ground-level ozone measurements matched those recorded in 2012. Forty-two states recorded their highest summer particle pollution readings within a decade, and forty-five experienced increased ozone amounts. Such widespread decline reversed decades of environmental progress, shocking scientists who had celebrated steady improvement.
Several states suffered very serious impacts from these pollutants. California, Oregon, and North Dakota faced extreme amounts of tiny particles that entered deep into residents' lungs. Meanwhile, California, Utah, Texas, and Illinois saw dangerous ozone levels that threatened public health. City populations in these areas faced breathing problems, with hospitals reporting more patients arriving for respiratory issues and heart problems.
This disaster revealed basic weaknesses in current climate preparation strategies. Despite strong environmental laws, developed nations remain at risk from extreme weather events made worse by global warming. Experts stress that complete international cooperation, better fire prevention methods, and updated healthcare plans are necessary for handling future risks. The 2023 experience serves as a clear warning that protecting air quality requires working together across national borders.
