Q4. [3 marks] Answer: Renewable expansion shifts supply right (S1→S2). Equilibrium price falls (P1→P2), quantity rises (Q1→Q2). Teaching note: Use diagram features from placeholder. Mark: 1 shift, 1 price, 1 quantity.
Q5. [2 marks] Answer: Country B inflation fell from 2.1% to 1.7%; Country C fell from 5.8% to 4.2%; C consistently higher. Teaching note: Compare both years and levels. Mark: 1 each country trend.

Q8.

Q10. [3 marks] Answer: Bus demand↑ → derived demand for lithium↑ → lithium price and quantity↑ (diagram shows D_l1→D_l2). Teaching note: Derived demand chain. Mark: 1 bus, 1 lithium shift, 1 outcome.
Q11. [4 marks] Answer: EPR internalises externalities (1); reduces pollution (1); conserves resources (1); raises welfare via cleaner environment (1). Teaching note: Market failure correction. Mark: 1 each point.

Q15. [4 marks] Working: %ΔQ = (140-100)/100 = 40%; %ΔP = (8-10)/10 = -20%; PED = 40/-20 = -2. |PED|>1 so revenue rises when price falls. Answer: PED = -2, revenue rises. Teaching note: Formula PED = %ΔQ/%ΔP. Mark: 2 calc, 2 conclusion.
Q16. [3 marks] Answer: Max price below P_e → Q_d > Q_s → shortage. Diagram shows gap. Teaching note: Price ceiling effect. Mark: 1 ceiling, 1 gap, 1 shortage.
Q17. [5 marks] Answer: High share + network effects suggest power (2); but low switching costs imply contestability (2); conclusion nuanced (1). Teaching note: Monopoly criteria. Mark: as above.
Q18. [5 marks] Answer: Appreciation cuts import price (2); but domestic inflation remains (2); partial effectiveness (1). Teaching note: Policy trade-off. Mark descriptors.
Q19. [3 marks] Working: Multiplier = ΔGDP/ΔG = 6/2 = 3. Leakage: imports. Answer: 3, imports. Teaching note: Multiplier formula. Mark: 2 calc, 1 leakage.
Q20. [4 marks] Answer: Retraining fixes immobility (2); EPR fixes externality (2); both raise welfare. Teaching note: Synthesise extracts. Mark: 2 each.
