    • 34 micrograms per cubic metre
    • 50 micrograms per cubic metre
    • 5 micrograms per cubic metre

  4. Delhi's average PM2.5 in 2023 was 92. How does this compare with the WHO safe limit of 5?

    • About the same as the safe limit
    • About 5 times lower than the safe limit

    • 24 micrograms per cubic metre
    • 92 micrograms per cubic metre
    • 82 micrograms per cubic metre
    • 58 micrograms per cubic metre

    • Beijing, by 24 micrograms per cubic metre
    • They are exactly equal in their readings
    • Beijing, by 58 micrograms per cubic metre, the difference from London
    • London, by 10 micrograms per cubic metre

  7. Delhi's PM2.5 was 92 and London's was 10. How much higher is Delhi?

    • 62 micrograms per cubic metre
    • 72 micrograms per cubic metre
    • 82 micrograms per cubic metre
    • 92 micrograms per cubic metre

  8. Which of these burns fuel and pollutes city air?

    • Vehicles burning petrol and diesel
    • Rain falling on rooftops and draining into the drains below
    • Parks with many trees that shade the people walking through
    • Rivers flowing through the city, carrying water to the sea

  9. Which of these is a major human source of air pollution in many large Asian cities?

    • Traffic fumes from vehicles
    • Pollen blown in from forests
    • Sea spray from the nearby ocean
    • Ash from volcanic eruptions

  10. Which health effect is linked to breathing dirty air for years?

    • Asthma, heart disease and early deaths
    • Faster healing of small cuts and bruises on the skin
    • Improved eyesight in children who live near busy roads
    • Stronger bones and better sleep for children and adults

  11. Why are PM2.5 particles so dangerous to health?

    • They only affect plants and not people, so they are harmless
    • They make the air smell sweet and fresh in the morning
    • They are tiny enough to reach deep into the lungs
    • They are heavy and fall to the ground at once near the road

  12. What does 'trade-off' mean?

    • Gaining one thing means giving up some of another
    • A fair share of wealth between all people in the world
    • A deal that makes both sides equal in every respect
    • Trading goods for gold at a fixed price agreed by both sides

  13. Which description best fits a sustainable approach?

    • Ignoring pollution while the economy grows, and dealing with it later
    • Meeting needs today without harming the environment for the future
    • Using all fuel as fast as possible to grow the economy quickly
    • Building factories without any rules or checks on pollution

  14. Which step did China take to clean up its air?

    • It stopped all factory production in 2013 for a whole year
    • It built more coal power stations in every city across the country
    • It banned all cars and buses from driving on the city roads
    • It shut old coal plants and built solar and wind farms

  15. Beijing's PM2.5 fell from 89 in 2013 to 34 in 2023. By how much did it fall?

    • 25 micrograms per cubic metre
    • 55 micrograms per cubic metre
    • 89 micrograms per cubic metre
    • 123 micrograms per cubic metre

  16. Which statement correctly describes the trend in Beijing's PM2.5 since 2013?

    • It has fallen steadily
    • It has stayed unchanged
    • It has fallen and then risen to 92 again
    • It has risen steadily

  17. Growth brings jobs and higher incomes. Which is a cost of the same growth?

    • Lower demand for workers, so unemployment falls sharply
    • Fewer cars on the roads, with lower traffic and quieter streets
    • Cleaner rivers and greener cities with more parks each year
    • Dirty air from more factories, cars and power stations

  18. Why do many fast-growing Asian cities have dirty air?

    • Growth brings only rain and no smoke, so the air stays clean
    • Growth closes all factories and power stations in the cities, so the air should be clean but is not
    • Growth stops people from driving any vehicles on the roads
    • Growth burns more coal, petrol and diesel, and crop waste and rubbish

  19. Which judgement best evaluates whether growth and clean air can go together?

    • Clean air matters only to rich countries that can afford it
    • They can never go together under any conditions in any country, because growth always means dirtier air for everyone
    • They can go together if cleaner energy and transport are used, but it takes choices and money
    • Growth is always good, so pollution does not matter to anyone

  20. What is the main reason a country might accept dirty air while it grows?

    • Pollution has no effect on workers or the economy in any region
    • Dirty air is good for children's health and helps them grow strong, which is why some towns keep the smog
    • Smog stops people needing healthcare, so hospitals are less busy
    • Jobs and higher incomes may seem more urgent in the short term, creating a trade-off
