QUESTION TYPE: Principle – Strengthen
CONCLUSION: Using peat moss as a soil conditioner is not environmentally sound.
REASONING: Peat moss contributes a lot of oxygen to the atmosphere, and gardeners are using peat moss faster than it can be replaced.
ANALYSIS: The answers to principle questions often seem blindingly obvious.
Approach these as if you were a space alien. What is ‘environmentally sound’? The stimulus doesn’t say.
We need a principle that says whatever the gardeners are doing (depleting oxygen, etc.) is environmentally unsound.
- This just shows that it’s possible that using peat moss is environmentally unsound. It doesn’t show that it is unsound.
- CORRECT. The gardeners will eventually significantly reduce the amount of oxygen entering the atmosphere if they deplete peat moss. This shows that doing so is environmentally unsound.
- This tells us how to show something is environmentally sound. We want to show that using peat moss is not environmentally sound.
- Same as C.
- This tells us when to ban something. But it doesn’t tell us when something is ‘environmentally unsound’.
