Internal combustion: applications and uneven diffusion

Twelve introductory lessons, 36 explained tasks, twelve analytical models and four selected comparison workshops introduce revised International AS enquiry 9.4. The sequence introduces the March guarantee and April reciprocity, British warnings and entry, selected German expansionist aims, April planning, June coordination, the final August order, Halder’s Western estimate and Raeder’s later testimony. Four of seventeen editorial working entries have partial introductory links; these are planning aids, not an official denominator or completion percentage. This is partial coverage, not full AS or A Level preparation. These introductions do not complete those four entries or the wider enquiry. The August treaty and protocol, fuller French and Polish perspectives, the wider history of German aims and command differences, Danzig and the Corridor, British preparation, German alliances and a weighed overall explanation remain unfinished. The other thirteen editorial entries remain wholly unlinked in this sequence. C-120 is a selected partial English documentary translation; omitted annexes are not reconstructed. Halder’s translated notes are fragmentary and not official OKH war diaries. Retrospective testimony is identified separately. Earlier enquiry 9.3 lessons receive no automatic 9.4 credit. Historical depth, wider authentic reading, subject-specialist review, full source sets, timed papers and calibrated marking remain unfinished. Existing 2026 lessons receive no automatic revised-year coverage credit. One hundred and three introductory lessons, 309 explained tasks, 103 analytical models and seventeen selected comparison workshops address revised International AS enquiry 9.3. This is partial coverage, not full AS or A Level preparation. All 24 editorial working entries have introductory links; these are not an official denominator or a completion percentage. The sequence introduces British and French foundations, selected ideological arguments, rearmament and the Rhineland, Anschluss, the Sudetenland negotiations, Munich and the March 1939 occupation. Selected public-consent evidence, British opposition, German resource mechanisms and production forecasts, strategic expectations and Italian intervention conditions are introduced. This does not complete German or Italian resource balances, psychological or causal evaluation, or the wider effects of appeasement. Public opinion and opposition need wider sources, chronology, French perspectives and policy effects. Wider British, French and German comparisons, affected perspectives, economic costs, counterfactual alternatives and enquiry 9.4 remain unfinished. The eight-demand memorandum has been checked in the English documentary edition, not the full original speech or every translation. Prague, Runciman, negotiations and Munich still need fuller implementation and outcomes. Historical depth, wider authentic reading, subject-specialist review, full source sets, timed papers and calibrated marking remain unfinished. Existing 2026 lessons receive no automatic revised-year coverage credit. Eighteen further lessons introduce revised International AS enquiry 7.1 on imperialism in Africa; twenty-six further lessons introduce enquiry 7.2 on imperial rivalries and diplomacy; twenty-two further lessons introduce enquiry 7.3 on Japan’s emergence; twenty-seven further lessons introduce enquiry 7.4 on American emergence.

The Poland lesson is also linked from the extremism enquiry to cover its final expansion-policy example. Sixteen lessons introduce four enquiries on China and Japan, with four lessons per enquiry. Six further workshops compare selected primary-document paraphrases: two in Russia, two in the American document topic and two in China and Japan.

Wider regional and authentic reading, historical depth, subject-specialist review, complete four-source assessment, full-paper preparation and calibrated marking remain unfinished. Other revised teaching remains unfinished. The 2026 lessons are not automatically validated for revised years. It mixes enquiry-level entries with broader unbuilt topic headings, so its linked count is not a syllabus-completion percentage.

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.

A selected Smith/Thomas comparison and a dated official election-table exercise distinguish shared opposition, different institutions, audience, votes and influence.
