QUESTION TYPE: Must be False
- Britain’s economy was 5x larger in 2000 than in 1880.
- Britain’s per capita emissions of CO2 stayed the same over that period.
ANALYSIS: It’s helpful to think through scenarios. We know emissions are the same, per capita. But that’s not the same as total emissions. Britain’s total emissions could have grown, if Britain had more people in 2000. (per capita = per person).
So the single fact we know is: per capita emissions stayed the same despite economic growth. The right answer contradicts this.
Another approach is to scan through the answers quickly. You’re looking for one which has factors directly related to the stimulus. Many wrong answers mention technology, laws, etc: factors which aren’t mentioned in the stimulus. For something to be “must be false”, the stimulus had to address it.
- This is possible. Britain’s per capita emissions didn’t decline, but that’s just one example. Some other country might have seen a per capita decline.
- The stimulus says nothing about what countries can afford.
- We have no idea if this is true. The stimulus didn’t mention technology.
- This is possible. The stimulus was about per capita emissions, whereas this answer is about total emissions. Total emissions will rise if per capita emissions stay the same but population grows.
- CORRECT. This contradicts the stimulus. In the stimulus, Britain’s economy grew, but per capita emissions did not increase.
