Q31To what extent10 marks
To what extent, if at all, do the data suggest that the reliance on fossil fuels to produce energy is falling? You must use the data in Extract C to support your assessment.

TopicPrice determination in a competitive marketCommodity marketsExternalities

Examiner insight

What to cover
Use the data to show changes in the share of fossil fuels over time.
Evaluation
Judge: absolute use versus share, and regional differences.
Watch out
Quote numbers from the extract.
Q32Explain15 marks
Explain how a sustained low world market price for oil would be likely to affect the economic development of a less economically developed oil-producing country such as Nigeria or Venezuela.

TopicThe international economyDevelopment

Examiner insight

What to cover
Low oil prices cut export revenue, tax revenue and investment, harming development. Diversification may follow.
Watch out
Link to development indicators, not only growth.
Q33Recommend25 marks
After considering Extract E, and the original evidence in Extracts A, B, C and D, would you recommend to the members of OPEC that they continue to restrict the supply of oil to try to raise the world market price of oil? Justify your recommendation.

TopicMarket structuresOligopolyCommodity markets

Examiner insight

What to cover
Restricting supply raises price when demand is inelastic, but encourages alternative energy and cheating in the cartel.

Supply restriction with inelastic demand.
Evaluation
Make a clear recommendation, considering US shale and long-run elasticity.
Watch out
Recommendation with conditions.
