#WHAT SECTION A IS

Six questions. Six marks. Six minutes. The easiest marks on the paper if you know the patterns. Every MCQ has one correct answer and three distractors designed by Pearson to represent the most common wrong answers.

---

#PART 1 — THE SIX DISTRACTOR TYPES

Pearson reuses the same six distractor types across every series. Recognising the type saves time and prevents the most common errors.

TYPE 1 — DIRECTION REVERSAL Correct mechanism, wrong direction. Fix: Circle the direction word in the question BEFORE reading options. Eliminate anything moving in the opposite direction.

TYPE 2 — NOMINAL VS REAL Gives nominal answer where real is required (ignores inflation). Fix: Any question with "real" → adjust for inflation. Real = Nominal − Inflation.

TYPE 3 — LRAS vs SRAS vs AD Applies demand-side policy to LRAS question or vice versa. Fix: LRAS = permanent productivity (education, infrastructure). SRAS = short-run cost changes. AD = demand changes. Demand policy never shifts LRAS.

TYPE 4 — MULTIPLIER FORMULA Uses k = MPC/(1−MPC) instead of k = 1/(1−MPC). Fix: The formula is ALWAYS k = 1/(1−MPC) = 1/MPW. Never invert it.

TYPE 5 — DISINFLATION VS DEFLATION Claims disinflation means prices fall. Fix: Disinflation = rate slowing (prices still rising). Deflation = prices actually falling (negative CPI).

TYPE 6 — CURRENT ACCOUNT COMPONENTS Includes goods only, excludes services, income, and transfers. Fix: Current account = goods + services + primary income + secondary income. All four.

---

#PART 2 — THE 60-SECOND ELIMINATION PROTOCOL

STEP 1: Read QUESTION only. Circle key concept and direction word.
STEP 2: Eliminate Type 1 (wrong direction) — usually removes 2 options.
STEP 3: Check real vs nominal (Type 2) if applicable.
STEP 4: Check LRAS vs SRAS vs AD (Type 3) if policy question.
STEP 5: Calculate if multiplier or % change (Type 4).
Time check: >45 seconds → mark best guess, move on, return after.

#PART 3 — WORKED QUESTIONS WITH FULL DISTRACTOR ANALYSIS

#A1 — AD SHIFT DIRECTION

"Which would cause a RIGHTWARD shift in AD?" A. A rise in interest rates — AD shifts LEFT (borrowing costs rise → C and I fall). Type 1. B. An increase in government expenditure — G rises → AD = C+I+G+X−M shifts RIGHT ✓ C. A fall in consumer confidence — C falls → AD shifts LEFT. Type 1. D. An appreciation of the exchange rate — X−M worsens → AD shifts LEFT. Type 1. Answer: B

---

#A2 — MULTIPLIER CALCULATION

"MPC = 0.75. Government spending rises £40bn. Change in national income?" A. £40bn — no multiplier applied. B. £120bn — uses k = MPC/(1−MPC) = 3. Type 4 (wrong formula). C. £160bn — k = 1/(1−0.75) = 4; £40bn × 4 = £160bn ✓ D. £200bn — uses k = 5 (wrong MPC assumed). Answer: C. Working: k = 1/0.25 = 4. ΔY = 40 × 4 = 160.

---

#A3 — REAL VS NOMINAL INTEREST RATE

"Nominal interest rate 6%, inflation 4%. Real interest rate?" A. 10% — adds instead of subtracts. Type 2. B. 2% — Real = 6 − 4 = 2% ✓ C. 6% — ignores inflation entirely. Type 2. D. 1.5% — divides. No basis. Answer: B. Real = Nominal − Inflation.

---

#A4 — LRAS VS SRAS

"A rise in imported raw material prices would most likely:" A. Shift LRAS leftward — LRAS reflects permanent productive potential; commodity spike is temporary. Type 3. B. Shift AD leftward — supply-side cost shock, not demand change. Type 3. C. Shift SRAS leftward — rising input costs → firms supply less at every price level ✓ D. Shift LRAS rightward — opposite of any supply deterioration. Type 1 + 3. Answer: C

---

#A5 — DISINFLATION VS DEFLATION

"Which best describes disinflation?" A. The price level is falling — deflation. Type 5. B. The inflation rate is negative — deflation. Type 5. C. The inflation rate is falling — price level still rising, rate decelerating ✓ D. Real GDP is falling — recession. Answer: C. Disinflation ≠ deflation.

---

#A6 — OUTPUT GAP

"An economy operating with a POSITIVE output gap means:" A. Actual output is below full employment output — negative output gap. Type 1. B. The price level is falling — positive gap generates inflation, not deflation. Type 1. C. Actual output is above full employment output — positive gap = Ye > Yfe ✓ D. The economy is in recession — recession = negative gap. Type 1. Answer: C

---

#A7 — CURRENT ACCOUNT

"A current account deficit means:" A. Government spending exceeds tax revenue — fiscal deficit, not current account. B. Exports of goods exceed imports of goods — that's a goods trade surplus. Type 6 confusion. C. Total payments for imports of goods, services, income and transfers exceed total receipts — all four components ✓ D. Capital outflows exceed capital inflows — capital account, not current account. Answer: C. All four CA components required.

---

#A8 — EXCHANGE RATE

"A depreciation of the domestic currency will most likely:" A. Reduce domestic price of imports — depreciation RAISES import prices. Type 1. B. Reduce the foreign currency price of exports — exports become cheaper for foreign buyers ✓ C. Immediately improve the current account — J-curve: short-run it WORSENS. Type 1. D. Increase the real exchange rate — depreciation REDUCES real exchange rate. Type 1. Answer: B

---

#A9 — PHILLIPS CURVE

"Moving along the SRPC from high to low unemployment causes:" A. Inflation rate to fall — moving to LOW unemployment = moving UP the SRPC = inflation RISES. Type 1. B. SRPC to shift left — a shift is caused by supply shocks, not movement along. C. Inflation rate to rise — tight labour market → wage pressure → CPI rises ✓ D. SRPC to shift upward — shift = supply shock. Not movement along. Answer: C

---

#A10 — TYPES OF UNEMPLOYMENT

"A worker made redundant because robots replaced their assembly line role is experiencing:" A. Cyclical unemployment — demand-deficient, recession-caused. Technology ≠ recession. B. Frictional — temporary between jobs. Technology replacement is permanent. C. Seasonal — predictable seasonal pattern. Technology ≠ seasonal. D. Structural — skills mismatch from technological or industrial change ✓ Answer: D

---

#A11 — GDP GROWTH CALCULATION

"Real GDP rose from £1,400bn to £1,470bn. GDP growth rate?" A. 70% — confuses absolute change with percentage change. B. 4% — [(1470−1400)/1470] × 100 = wrong denominator used. C. 5% — [(1470−1400)/1400] × 100 = [70/1400] × 100 = 5% ✓ D. 7% — arithmetic error or wrong base. Answer: C. Always use the ORIGINAL value as denominator.

---

#A12 — PERCENTAGE POINT VS PERCENTAGE CHANGE

"Unemployment rose from 4.0% to 4.5%. The percentage POINT change is:" A. 12.5% — this is the percentage CHANGE: [(4.5−4.0)/4.0] × 100 = 12.5%. Wrong type. B. 0.5 percentage points — direct subtraction: 4.5 − 4.0 = 0.5pp ✓ C. 8.5% — arithmetic error. D. 0.125 — divides 0.5 by 4.0 without multiplying by 100. Answer: B. Percentage POINT = subtraction. Percentage CHANGE = formula.

---

#A13 — SUPPLY-SIDE LRAS SHIFT

"Which policy shifts LRAS rightward?" A. Cut in interest rates — AD shift only. Type 3. B. Increase in government current spending — AD shift. Type 3. C. Investment in worker training and education — human capital → productivity → LRAS ✓ D. Reduction in the base rate — AD shift. Type 3. Answer: C. Only permanent productivity improvements shift LRAS.

---

#A14 — AUTOMATIC STABILISERS

"Which of the following is an example of an automatic fiscal stabiliser?" A. A government decision to increase infrastructure spending — discretionary, not automatic. B. A central bank decision to cut interest rates — monetary policy, not fiscal. C. A rise in unemployment benefit payments during a recession ← CORRECT — automatic, legislated, no new decision required ✓ D. A decision to reduce the basic rate of income tax — discretionary fiscal policy. Answer: C. Automatic stabilisers operate without new policy decisions.

---

#A15 — COST-PUSH INFLATION

"A global energy price surge would most likely cause:" A. AD to shift rightward — energy prices are a supply-side cost, not demand. B. LRAS to shift leftward — LRAS reflects long-run potential, not a commodity spike. Type 3. C. SRAS to shift leftward and the price level to rise ✓ D. SRAS to shift rightward and the price level to fall — Type 1 (wrong direction). Answer: C. Rising input costs shift SRAS left → stagflation (P rises, Y falls).

#PART 4 — THE 10 MOST TESTED CONCEPTS (frequency analysis 2019–2026)

#CONFIRMED FORMULAS — QUICK REFERENCE

k = 1/(1−MPC) = 1/MPW
MPC=0.8 → k=5 | MPC=0.75 → k=4 | MPC=0.6 → k=2.5

Real rate = Nominal − Inflation

GDP growth % = [(Y₂−Y₁)/Y₁] × 100

Real GDP = (Nominal GDP / CPI) × 100

GDP per capita = GDP / Population

Percentage POINT change = direct subtraction
Percentage CHANGE = [(new−old)/old] × 100
