This quiz contains 20 questions based on data response skills.
Answer all questions in the spaces provided.
Use diagrams where requested and label them clearly.
Marks for each question are shown in brackets.

Section A: Extract and Table Interpretation (Questions 1–5)

Extract 1:
The Southeast Asian semiconductor industry saw mixed output in 2023. Vietnam recorded a 12% rise in chip exports, while Malaysia reported a 4% decline. Government subsidies in Vietnam supported new fabrication plants, whereas in Malaysia, labour shortages constrained production.

Table 1: Electric Vehicle (EV) Battery Material Prices (USD per kg), 2021–2023

Material	2021	2022	2023
Lithium	15	38	22
Cobalt	30	35	28
Nickel	12	20	18

With reference to Extract 1, identify one country that increased chip exports and one that declined. [2]

Using Table 1, calculate the percentage change in lithium price from 2021 to 2023. Show your working. [2]

With reference to Table 1, describe the trend in cobalt prices from 2021 to 2023. [1]

Explain one possible reason why Vietnam's subsidies led to higher chip exports using a demand-supply diagram of the chip market. [3]

Diagram for Q4 (ALEVEL Economics H2)

Generated diagram for Q4.

With reference to Extract 1 and Table 1, suggest one way in which higher battery material prices could affect EV producers. [2]

Section B: Diagram and Data-Based Analysis (Questions 6–10)

Extract 2:
In 2024, a drought in Brazil reduced coffee bean harvests. Global coffee prices rose by 18%. Simultaneously, a new coffee substitute made from barley gained popularity in Europe.

With the aid of a diagram, explain how the drought in Brazil affects the market for coffee beans. [3]

Diagram for Q6 (ALEVEL Economics H2)

Generated diagram for Q6.

Using Extract 2, explain what is meant by a "substitute" in economics. [2]

With reference to Extract 2, explain how the popularity of barley coffee substitute may affect demand for coffee beans. [2]

Table 2 shows rice output (million tonnes). Compute the average annual growth rate of Country X from 2021 to 2023. [2]

Year	2021	2022	2023
X	100	105	110

Using a diagram, explain how a successful barley substitute reduces consumer surplus in the coffee market. [3]

Diagram for Q10 (ALEVEL Economics H2)

Generated diagram for Q10.

Section C: Source-Based Evaluation (Questions 11–15)

Extract 3:
The government of Country A imposed a tariff of 20% on imported solar panels to protect local manufacturers. Local output rose by 15%, but consumer prices increased by 10%. Retaliatory tariffs from neighbouring countries reduced Country A's exports of electronics by 8%.

With reference to Extract 3, identify the two effects of the tariff on the local economy. [2]

Using Extract 3, calculate the new consumer price index effect if the base price was $200 before tariff. [2]

With the aid of a diagram, explain how the tariff affects consumer surplus in Country A's solar panel market. [3]

Diagram for Q13 (ALEVEL Economics H2)

Generated diagram for Q13.

Explain one possible unintended consequence of the retaliatory tariffs mentioned in Extract 3. [2]

Evaluate whether the tariff was beneficial for Country A's social welfare. Use evidence from Extract 3. [6]

Section D: Synthesis and Higher-Order Data Response (Questions 16–20)

Extract 4:
Country B introduced a carbon tax of $50 per tonne in 2022. Emissions fell by 9% by 2023. However, energy-intensive firms relocated to countries without carbon pricing, causing a 3% drop in manufacturing jobs. Renewable energy investment rose by 25%.

With reference to Extract 4, identify two economic effects of the carbon tax. [2]

Using a diagram, explain how a carbon tax corrects a negative externality in the energy market. [3]

Diagram for Q17 (ALEVEL Economics H2)

Generated diagram for Q17.

With reference to Extract 4, explain the concept of "capital flight" as shown by firm relocation. [2]

Calculate the net percentage change in manufacturing jobs if the 3% drop is the only employment effect. [1]

Discuss whether a carbon tax is a better policy than a subsidy for reducing emissions, using evidence from Extract 4. [8]

Answers

A-Level Economics H2 Quiz - Data Response (Answer Key)

Total Marks: 40
Topic: Data Response

Section A: Extract and Table Interpretation (Q1–5)

Q1. [2 marks]

Vietnam increased chip exports (by 12%). [1]
Malaysia declined (by 4%). [1]
Teaching note: Extract 1 explicitly states Vietnam's rise and Malaysia's fall. Students should quote figures for precision.

Q2. [2 marks]
Working:
Lithium 2021 = $15, 2023 =$ 22.
Percentage change = ((22 − 15) / 15) × 100 = (7 / 15) × 100 ≈ 46.67%. [2 for correct working and answer]
Common mistake: Using wrong base year or omitting ×100.

Q3. [1 mark]
Cobalt prices rose from $30 (2021) to$ 35 (2022) then fell to $28 (2023); net decline over period. [1]
Marking: Award for stating rise then fall or net decrease.

Q4. [3 marks]

Diagram: Subsidy shifts supply right from S1 to S2. [1]
Lower price, higher Q. [1]
Explanation: Subsidy lowers cost of production, increases supply, raises exports. [1]
Teaching note: Subsidy = negative cost → supply increases. Link to Extract 1's fabrication plants.

Q5. [2 marks]
Higher material prices raise EV production costs (cost-push), reduce profit margins, or force price increases. [2] Any one valid suggestion with reference to Table 1.

Section B: Diagram and Data-Based Analysis (Q6–10)

Q6. [3 marks]

Diagram: Leftward supply shift (S1→S2). [1]
Price rises, quantity falls. [1]
Drought reduces supply → scarcity → higher P. [1]
Teaching note: Supply shock from weather is a non-price determinant (shift).

Q7. [2 marks]
A substitute is a good that can replace another; if price of coffee rises, demand for barley coffee rises. [2] Definition + context from Extract 2.

Q8. [2 marks]
Barley substitute reduces demand for coffee beans (leftward D shift) as consumers switch. [2] Link to Extract 2 popularity.

Q9. [2 marks]
Growth 2021→2023: (110−100)/100 = 10% over 2 years. Average annual = 10% / 2 = 5%. [2]
Working: (110−100)/100 = 0.10; /2 = 0.05 = 5% p.a.

Q10. [3 marks]

Diagram: D shifts left (D1→D2). [1]
Consumer surplus shrinks from CS1 to CS2. [1]
Substitute reduces coffee demand, lowers price, less CS. [1]

Section C: Source-Based Evaluation (Q11–15)

Q11. [2 marks]
Local output rose 15% [1]; consumer prices up 10% [1].

Q12. [2 marks]
Base $200 + 10% =$ 200 × 1.10 = $220. [2]
Note: Tariff passed to consumers per Extract 3.

Q13. [3 marks]

Diagram: Tariff raises price Pw→Pt. [1]
CS falls from area under D above Pw to smaller area above Pt. [1]
Explanation: higher price, lower Q reduces CS. [1]

Q14. [2 marks]
Retaliatory tariffs reduced electronics exports by 8% → job losses or trade war. [2] Any unintended consequence explained.

Q15. [6 marks] Mark descriptors:

Identify protection benefit: local output +15% (1)
Cost: consumer price +10% (1)
External loss: export drop 8% (1)
Net welfare: producer gain vs consumer loss + trade retaliation (2)
Judgement: ambiguous; short-run industry gain, long-run welfare ambiguous (1)
Teaching note: Use CS/PS analysis; tariff creates DWL but protects jobs.

Section D: Synthesis and Higher-Order (Q16–20)

Q16. [2 marks]
Emissions fell 9% [1]; manufacturing jobs −3% [1].

Q17. [3 marks]

Diagram: MPC shifts to MSC via tax. [1]
Corrects externality: Qm→Qe. [1]
Tax internalises cost. [1]

Q18. [2 marks]
Capital flight = firms moving abroad to avoid tax/cost, shown by relocation. [2]

Q19. [1 mark]
Net change = −3% (only effect given). [1]

Q20. [8 marks] Mark scheme:

Carbon tax: emissions −9%, jobs −3%, investment +25% (2)
Subsidy alternative: could support renewables without job loss but costs gov revenue (2)
Evaluation: tax effective but distributional cost; subsidy needs funding (2)
Conclusion with evidence-based judgement (2)
Teaching note: Synthesis from Extract 4; compare instruments using efficiency and equity.
