Compare international pressures without treating the two oil crises as identical events.
Exam scope and assessment notes
Partial 2026 course: introductory context across the twelve AS topics, with selected document workshops, not full AS or A Level preparation. All three Paper 3 alternatives have introductory context, historiography and original interpretation exercises; Italy, Stalin’s Russia, Hitler’s Germany and Britain have introductory depth pathways across their four enquiries. The USA in the late 1940s/1950s and the 1960s/1970s have introductory American depth pathways; the 1980s/early-1990s theme now introduces all four enquiries with original teaching and two longer essay workshops. All four American themes now have introductory teaching and longer essay workshops, including US foreign policy, 1944–1992. The US–Soviet theme introduces all four enquiries through thirty core lessons and two longer essay workshops. Forty-one lessons introduce all four East and Southeast Asia enquiries: eight on post-war change, nine on Korea, twelve on Vietnam and twelve on Sino-American relations. Eight lessons introduce the African independence enquiry through Ghana, Nigeria, Senegal, Kenya and comparative reasoning. Nine further lessons introduce government, economic and social challenges after independence. Thirteen further lessons introduce Cold War involvement, Chinese support, non-alignment and Pan-Africanism. Twelve further lessons introduce UN involvement in Congo and Somalia, with 1993–1995 explicitly labelled as later context beyond the theme’s 1992 endpoint. Ten lessons introduce the creation-of-Israel enquiry. Twenty further lessons introduce wars and peace efforts in 1948–1979. Seventeen further lessons introduce superpower motives, oil, American and Soviet policies and their consequences through 1991. Twenty-one further lessons introduce the Iranian Revolution, Iran–Iraq War and 1990–1991 Gulf War. All four 2026 Middle East enquiries have introductory lessons; broader reading, depth, specialist review and full assessment remain unfinished. The separate 2027–2029 requirements are not mapped by these 2026 lessons. A separately labelled revised-year orientation and Eastern Europe enquiries 7.1–7.4 introductions and South Africa enquiries 8.1–8.3 and Zimbabwe enquiry 8.4, followed by Malaya enquiry 9.1 and introductory sequences for Malaysia formation enquiry 9.2 and Indonesian nationalism enquiry 9.3, with partial preparation, revolution, 1950s challenges and New Order teaching in enquiry 9.4, are available; other revised teaching remains unfinished. Source summaries are original StudyForA paraphrases, not quotations, complete documents or simulated eyewitness sources. Primary documents, historians’ arguments and original exercises are identified separately. Guided source comparisons, interpretation exercises and analytical models are not full papers, calibrated marking or Cambridge grades. Broader authentic source reading, historical depth and subject-specialist review remain required. The USA in the 1960s and 1970s is one theme within the American Paper 4 depth study in 2026. The official paper is 105 minutes and 60 marks, with two questions from the chosen depth study. These lessons and original planning briefs introduce USA in the 1960s and 1970s; broader historical depth, full timed papers and calibrated marking remain unfinished.

Enquiry brief and analytical model
This is an original StudyForA enquiry brief, not a quotation, a primary document or a historian’s extract. Use it to plan your own argument and read the linked evidence. The USA in the 1960s and 1970s is one theme within the American Paper 4 depth study in 2026. The official paper is 105 minutes and 60 marks, with two questions from the chosen depth study. These lessons and original planning briefs introduce USA in the 1960s and 1970s; broader historical depth, full timed papers and calibrated marking remain unfinished.

StudyForA enquiry brief · Foreign competition, oil and external shocks
[1] Compare foreign competition and separate oil disruptions through their effects on costs, household spending and policy choices. This is an original enquiry prompt.
1. How far do external challenges explain deteriorating economic conditions?
Compare after trying
Foreign competition exposed weaknesses and opportunities within particular American sectors, while international monetary strains influenced policy choices. Their impact depended on productivity, investment and consumer demand, so neither imports nor a national trade balance supplies a complete welfare judgement.
The 1973 embargo and the Iranian disruption of 1978–1979 had distinct political origins. Both affected costs and expectations in an energy-dependent economy. Lifting the earlier embargo did not automatically restore previous prices, and shared effects do not justify describing one uninterrupted worldwide restriction.
External pressure therefore belongs alongside domestic explanations. Inflation predating the 1973 embargo and variation between industries qualify a sole-cause account. A supported judgement explains how shocks interacted with demand, monetary responses and household resources rather than making foreign events responsible for every difficulty.
Why this response fits
- Connects relevant, dated evidence with the judgement.
- Tests the explanation against contrasting groups, outcomes and limits.
Competition and exposure
European and Japanese recovery created stronger competitors for American producers. Firms faced pressure over prices, productivity and product quality, while consumers could benefit from alternative goods. An import’s availability did not mean every domestic industry declined, and a trade balance was not the same measure as household welfare. Explain how competition affected particular sectors, investment and employment before assigning one national verdict to international exchange.
Cold War expenditure and international monetary commitments also influenced resources and financial relations. Nixon’s 1971 address presented trade and dollar pressures as reasons for a new programme, including an import surcharge and suspension of gold conversion. Its account was an administration’s argument for action. The speech cannot independently prove that foreign producers alone caused American difficulties or that every announced measure achieved the promised outcome.
Two oil shocks with separate causes
Arab oil producers imposed an embargo against the United States during the October 1973 Arab–Israeli war, alongside production decisions that altered the world market. OAPEC and OPEC were related but different organisations; membership should not be collapsed into one universal actor. The embargo was lifted in March 1974, but ending it did not restore the earlier price level. Duration of a restriction and persistence of its economic consequences are distinct questions.
The 1978–1979 Iranian Revolution disrupted a major oil producer and intensified uncertainty about supply. It was not simply the same Arab embargo restarted. Expectations, precautionary purchases, production elsewhere and policy responses affected how disruption became higher prices and shortages. A comparison should identify differences in origin alongside the common importance of energy, rather than treating all oil-exporting states and decisions as identical.
Trace the domestic effects
More expensive energy raised transport, heating and industrial costs while absorbing household income that might otherwise purchase other goods. Firms faced pressure on prices, profits and output, with different exposure across activities. Monetary responses could influence whether a relative energy-price shock became persistent broader inflation, but they could not instantly create oil. Inflation already rising before October 1973 also rules out making that embargo the origin of every earlier increase. A supported explanation weighs external shocks with domestic demand, productivity, policy and expectations through consistent dates.

Pause and explain
Which comparison of the oil crises is supported?
Worked example
Does lifting an embargo imply the old oil price returns immediately?
Show the worked solution
- Identify the restriction’s end.
- Identify the separate price outcome.
- Consider supply, demand and expectations.
Answer No. Ending a restriction changes access, but the resulting price also depends on wider market conditions, production decisions and expectations.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
Guided: Explain how higher fuel costs could weaken purchases beyond the energy sector.
Give me a hint
Follow the household budget.
Compare my reasoning
- Identify essential fuel spending.
- Hold income constant in the illustration.
- Explain the remaining purchasing power.
With unchanged income, a household paying more for essential transport and heating has less available for other goods. Reduced orders can affect firms beyond oil itself. This mechanism depends on budgets and alternatives; it does not establish an equal loss for every household or an exact national multiplier without further evidence.
Look for these in your work
- Connects costs and demand
- Retains household variation
Independent: Compare the political origins of the 1973 and 1979 shocks.
Give me a hint
Use separate dates and actors.
Compare my reasoning
- Place the Arab–Israeli war and embargo.
- Place the Iranian Revolution.
- Identify a shared economic channel.
The 1973 embargo and production measures were linked to Arab–Israeli conflict, while the later Iranian disruption arose from revolution and uncertainty around a major producer. Both affected an energy-dependent market, but shared cost effects do not make their actors, restrictions or chronology identical.
Look for these in your work
- Preserves distinct origins
- Explains a shared transmission channel
Application: Revise a fictional factory history blaming its 1971 difficulties on the October 1973 embargo.
Give me a hint
Restore the sequence and ask for sector evidence.
Compare my reasoning
- Date the earlier difficulty.
- Exclude the later event as its original cause.
- Investigate competition, investment and earlier costs.
A 1973 event cannot cause a difficulty already present in 1971. The account should investigate earlier demand, competition, investment and monetary conditions using factory evidence. The later shock may explain an additional burden or delayed recovery, but should not replace the earlier causes with an impossible chronology.
Look for these in your work
- Rejects the chronological error
- Names evidence for the earlier problem
Common mistakes
- Calling OAPEC and OPEC identical
- Making 1979 a repeat of the same embargo
- Equating an embargo’s end with full economic recovery
