The 20 questions

  1. Which three approaches are linked by the specification to reducing the use of resources?

    • Extracting, refining, selling
    • Mining, burning, burying
    • Reducing, reusing, recycling
    • Crushing, melting, casting

  2. Which material is produced from limited raw materials?

    • Wool
    • Cotton
    • Wood
    • Glass

  3. What environmental impact is caused by quarrying and mining raw materials?

    • Acid rain
    • Global cooling
    • Depleting ozone
    • Disturbing land

  4. Which product is given as an example that can be reused?

    • Glass bottles
    • Limestone
    • Metal ores
    • Crude oil

  5. What process is used to recycle glass bottles that cannot be reused?

    • Dissolving in acid
    • Shredding and gluing
    • Burning in air
    • Crushing and melting

  6. How are metals typically recycled according to the specification?

    • Melting and recasting
    • Dissolving in water
    • Freezing and shattering
    • Heating with carbon

  7. What does the required amount of separation for recycling depend on?

    • Transport cost
    • Factory location
    • Weather conditions
    • Material and properties

  8. What can be added to iron from a blast furnace to reduce iron extraction?

    • Scrap steel
    • Limestone
    • Coke
    • Bauxite

  9. A factory needs 500 kg of iron, and 150 kg comes from scrap steel. How much iron must be extracted from ore?

    • 500 kg
    • 150 kg
    • 650 kg
    • 350 kg

  10. Why is reusing glass bottles often preferable to recycling them?

    • It is heavier
    • Avoids melting energy
    • It changes colour
    • It creates jobs

  11. What is the primary benefit of increasing the recycled content of a product?

    • Increasing density
    • Conserving raw materials
    • Speeding up corrosion
    • Lowering electrical conductivity

  12. What is a major advantage of designing products to be easily dismantled?

    • Increased weight
    • Higher market price
    • Faster chemical reactions
    • Easier material separation

  13. What is the most preferred resource management strategy among end users?

    • Reduction in use
    • Deep burial
    • Incineration
    • Landfill disposal

  14. Which activity directly reduces the environmental impacts of mining?

    • Increasing extraction
    • Using more energy
    • Recycling metals
    • Creating landfill sites

  15. Why does recycling metal generally use less energy than initial extraction?

    • Lower temperatures
    • Weaker bonds
    • Faster cooling
    • No transport

  16. What factor must be weighed against resource savings when evaluating recycling schemes?

    • Plant design
    • Mining taxes
    • Collection energy
    • Metal density

  17. What manufacturing step is avoided when reusing a glass bottle rather than recycling it?

    • Washing the glass
    • Sorting the glass
    • Mining raw materials
    • Melting the glass

  18. What is the standard method for managing a metal object that is no longer needed?

    • Landfill disposal
    • Open burning
    • Recycling
    • Direct reuse

  19. A scrap steel mix is 20% scrap, with the rest from the furnace. How much furnace iron is needed for 1000 kg of steel?

    • 200 kg
    • 1000 kg
    • 80 kg
    • 800 kg

  20. Why does reducing material use lead to a lower energy demand?

    • Energy is destroyed
    • Materials create heat
    • Raw materials expand
    • Less processing required
