Answers

1. Woodrow Wilson (USA), David Lloyd George (Britain), Georges Clemenceau (France) [1] [1] [1].

2. Any two: to maintain world peace/prevent future war, to promote international cooperation, to improve social and economic conditions worldwide, to encourage disarmament [1] [1].

3. Any three, 3 marks each: France had suffered enormous casualties and physical destruction on its own territory, unlike Britain or the USA, giving Clemenceau strong domestic pressure to secure compensation and security [1] [1] [1]; Clemenceau wanted to permanently weaken Germany’s ability to threaten France again, given France had been invaded by Germany twice in living memory (1870, 1914) [1] [1] [1]; he sought territorial and financial concessions (e.g. reparations, loss of territory such as Alsace-Lorraine) to both punish Germany and rebuild France [1] [1] [1].

4. Any two, 3 marks each: the League had no permanent armed force of its own, so it depended on member states voluntarily providing troops or sanctions, which they were often reluctant to do [1] [1] [1]; major powers were absent or left — the USA never joined, and Germany, Japan and Italy left or were expelled during the 1930s, weakening its authority and reach [1] [1] [1]; the requirement for unanimous decisions made swift, decisive action against aggression very difficult to achieve [1] [1] [1].

5. Any two, 3 marks each: Hitler pursued rearmament in open violation of the Treaty of Versailles, signalling clear intent to challenge the post-war settlement by force if necessary [1] [1] [1]; he pursued territorial expansion (e.g. remilitarising the Rhineland, the Anschluss with Austria, the annexation of the Sudetenland) that repeatedly tested whether Britain and France would resist, escalating tension each time they did not [1] [1] [1].

6. Any two, 4 marks each: ideological differences between capitalist Western democracies and the communist USSR resurfaced once the shared enemy (Nazi Germany) was defeated, removing the main reason for cooperation [1] [1] [1] [1]; disagreements over the future of Eastern Europe, particularly Poland and the wider Soviet sphere of influence, produced mutual distrust about the other side’s long-term intentions [1] [1] [1] [1].

7. Award up to 10 marks for a balanced argument reaching a clear judgement. Case for fairness: Germany was held responsible under the “war guilt” clause partly because its own actions (invading Belgium and France) had triggered the wider war, and some historians argue the terms were less harsh than Germany itself had previously imposed on defeated Russia [1] [1] [1]. Case for unfairness: the loss of territory, the size of reparations, and the military restrictions arguably went beyond what was needed for security and instead created lasting German resentment that later fed into support for extremist politics [1] [1] [1]. A strong answer weighs both cases explicitly and reaches an explicit conclusion, rather than simply describing the terms [1] [1] [1] [1].

8. Award up to 10 marks for a balanced argument. Case for “doomed from the start”: structural weaknesses (no armed force, absence of major powers, unanimity requirement) were built in from the League’s creation and never resolved [1] [1] [1]. Case against: the League had genuine early successes in some border and humanitarian disputes during the 1920s, suggesting failure was not inevitable but resulted from specific later decisions (e.g. the response to the Manchurian Crisis and the Abyssinian Crisis) [1] [1] [1]. A strong answer concludes with an explicit judgement on which case is stronger, using specific evidence [1] [1] [1] [1].

9. Award up to 10 marks for a balanced argument. Case for Hitler’s responsibility: his foreign policy aims and repeated territorial actions through the 1930s directly and deliberately challenged the post-war settlement [1] [1] [1]. Case for other causes: appeasement by Britain and France, the Treaty of Versailles’s own resentment-generating terms, and the League of Nations’ weakness all contributed to an environment in which aggression went unchecked [1] [1] [1]. A strong answer weighs Hitler’s own actions against these wider contributing factors before reaching a conclusion [1] [1] [1] [1].

10. Award up to 10 marks for an answer using at least two named regions/periods. Candidates might discuss containment succeeding in Western Europe (e.g. the Marshall Plan, NATO) while struggling or failing in parts of Asia (e.g. the outcome in Vietnam), or evaluate a specific policy’s mixed record across different Cold War decades [1] [1] [1] [1] [1] [1]. A strong answer reaches an explicit judgement about overall effectiveness rather than simply describing separate policies without comparison [1] [1] [1] [1].
