Question

1. which statement about air pollution is true?

air pollution has fewer negative health effects than smoking does.
air pollution is a concern only when you are outdoors.
health effects of air pollution are great for young children
staying indoors with the windows closed minimizes air pollution

Explanation:

• Air pollution can have significant negative health effects, often comparable to or even more widespread than smoking in some contexts (so the first option is wrong).
• Air pollution is a concern both indoors (from sources like cooking fumes, mold, etc.) and outdoors (so the second option is wrong).
• Air pollution has harmful, not “great” health effects on young children (so the third option is wrong).
• Staying indoors with windows closed can reduce exposure to outdoor air pollutants (like particulate matter from traffic, industrial emissions), minimizing the impact of air pollution to some extent.

Answer:

Staying indoors with the windows closed minimizes air pollution.
