Q

Test Your Understanding

UnderstandBand 3

1. Sustainability is best defined as:

AUsing up resources as fast as possible
BMeeting the needs of the present without compromising the ability of future generations to meet their own needs
CNever using any natural resources
DRecycling everything
UnderstandBand 3

2. A circular economy differs from a linear "take, make, waste" economy because it:

AMakes more products faster
BSends more waste to landfill
CKeeps materials in use through reduce, reuse, repair and recycle
DUses only fossil fuels
UnderstandBand 4

3. In the waste hierarchy, which option has the HIGHEST priority for reducing waste?

AReducing and reusing
BRecycling
CSending to landfill
DBurning for energy
UnderstandBand 4

4. The "planetary boundaries" framework describes:

AThe borders between countries
BThe orbit of the Earth
CLimits on how many people can live in a city
DSafe limits for nine Earth systems, several of which humans have already crossed
UnderstandBand 4

5. "Intergenerational equity" means:

AEveryone in one generation earns the same money
BFairness to future generations when we make decisions today
CEqual numbers of people in each generation
DSharing resources equally between countries
ApplyBand 4

6. Which is the MOST reliable secondary source of climate data for an investigation?

AA random social media post
BA friend's opinion
CThe Bureau of Meteorology, CSIRO, NASA or the IPCC
DAn advertisement
ApplyBand 4

7. In a fair investigation, the independent variable is:

AThe variable you deliberately change
BThe variable you measure as the result
CA variable you keep the same
DA mistake in the method
AnalyseBand 5

8. "Correlation does not prove causation" means:

ATwo things can never be linked
BData is always wrong
CCausation is impossible to test
DTwo variables changing together does not by itself prove that one causes the other
UnderstandBand 4

9. Which is an example of Aboriginal and Torres Strait Islander sustainable management of Country?

AClearing all native vegetation
BHarvesting only in season and protecting totemic species so populations remain healthy
CDraining wetlands for farmland
DIgnoring fire entirely
AnalyseBand 5

10. Which statement best captures the main message of this unit?

AClimate change cannot be measured
BSustainability is only about recycling
CScience, impacts, action and sustainability principles connect into one evidence-based effort to keep the planet liveable for future generations
DNothing can be done about the environment
