Q18. With reference to Extract 10, evaluate the effectiveness of exchange rate appreciation in controlling imported inflation.

Extract 10: "Country H allowed currency appreciation to lower import prices amid global oil spikes, but domestic demand inflation persisted."

Topic: Data Response
Total Marks: 40
Note: Syllabus-first content generated from LLM-inferred templates; not claimed as past-year exam derived.

Section A: Data Interpretation

Q1. [2 marks] Answer: Renewable share rose steadily from 12% (2019) to 30% (2023), an upward trend of 18 percentage points. Teaching note: Student should describe direction and magnitude from Table 1. Mark: 1 for correct start/end, 1 for noting increase.

Q2. [2 marks] Working: 30% – 12% = 18 percentage points. Answer: 18 percentage points. Teaching note: Simple subtraction; show units. Mark: 1 for working, 1 for answer.

Q3. [2 marks] Answer: Carbon tax raised cost of fossil power, while solar subsidies lowered renewable cost, shifting supply toward renewables. Teaching note: Link Extract 1 policy to incentive function of price mechanism. Mark: 1 for carbon tax, 1 for subsidy.

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.

Section B: Source-Based Analysis

Q6. [2 marks] Answer: Retraining reduces occupational immobility by giving coal workers new skills, easing structural unemployment. Teaching note: Factor immobility concept. Mark: 1 definition, 1 application.

Q7. [2 marks] Answer: Firms get lower hiring/search costs as workers are pre-skilled via government training. Teaching note: Cost advantage from reduced training expense. Mark: 1 identify, 1 explain.

Q8. [4 marks] Answer: Partly justified: infant industry needs protection to achieve scale (1); but 20% may be excessive (1); risk of inefficiency if not removed (1); lacks proof of future competitiveness (1). Teaching note: Use tariff justification criteria. Mark descriptors: 4 = balanced, 2–3 = one-sided.
