What action did the government take in response to the air pollution event?

• A. They distributed 5 million face masks to schoolchildren.
• B. They closed all factories
• C. They issued a water ban
• D. They built new roads

Answer: (A)

When a city faces a severe air pollution event, the goal is to cut people’s exposure to harmful pollutants, especially for those most at risk like children. Distributing millions of face masks to schoolchildren is a direct,迅 quick protective step that lowers inhaled pollutants for a group in which exposure can have immediate health impacts. It can be carried out rapidly without shutting down industry or disrupting daily life, making it an efficient short-term shield while longer-term pollution controls are pursued. The other options don’t fit the situation: closing all factories would cause widespread economic disruption and may be unnecessary; a water ban isn’t relevant to air quality; and building new roads could worsen pollution.
