O Level World History: Depth Studies — Practice Questions

These are original questions written for Marlbridge, testing source- evaluation technique and understanding of the Depth Studies’ structure rather than providing genuine historical sources or full document-based analysis, since these depend on the specific sources set in any given exam series. Use these alongside genuine study of your chosen Depth Study and official past papers.

Section A

1. Name the five Depth Studies. [5]

2. State the three things a strong source-evaluation answer should comment on. [3]

3. State which paper the Depth Studies component is assessed through. [1]

---

Section B

4. A student answering a source question on Depth Study B (Germany, 1918–45) describes only what a propaganda poster shows, without commenting on who produced it or why.

(a) Identify the weakness in this answer. [2] (b) Explain how the answer should be improved. [3]

5. A student writing about Russia in 1905 and 1917 treats both years as part of one continuous revolutionary process with a single outcome.

(a) Identify the factual weakness in this framing. [2] (b) Explain the correct distinction between the two years. [3]

6. Two sources on the same historical event appear to directly contradict each other.

(a) Identify the wrong way to resolve this in an exam answer. [1] (b) Describe the better approach, referring to origin and purpose. [3]

Section C

7. Explain why preparation for a Depth Study (assessed through Paper 2, a document-based paper) requires a genuinely different revision approach from preparation for the Core Content options. [6]

8. A student revising Depth Study E (The Second World War) prepares detailed knowledge of the European theatre only, reasoning that “a world war is still one war, so this should be enough.” Evaluate this reasoning. [6]

Worked answers

1. The First World War, 1914–18; Germany, 1918–45; Russia, 1905–41; The United States, 1919–41; The Second World War in Europe and the Asia-Pacific, 1939–c.1945. [5]

2. The source’s content; its origin (who produced it, when, and for what purpose); its value or limitations as evidence for the specific historical question being asked. [3]

3. Paper 2 (Document Questions). [1]

4. (a) The answer describes the poster’s content without evaluating its origin or purpose, which is what actually determines its value as historical evidence. [2] (b) The answer should identify that the poster was produced by the German government for public display, meaning its purpose was almost certainly propaganda intended to shape public opinion rather than record it — this limits its value as direct evidence of how ordinary Germans actually felt, though it remains valuable evidence of what the regime wanted people to believe or of the regime’s own self-presentation. [3]

5. (a) 1905 and 1917 were two distinct events with different causes and different outcomes — 1905 failed to remove the Tsar, while 1917 succeeded — so treating them as one continuous process with a single outcome misrepresents what actually happened. [2] (b) 1905 was a revolution that ultimately failed to remove the Tsar from power, though it did produce some limited reforms; 1917 was a separate revolution, over a decade later, that did succeed in removing the Tsar and eventually led to the consolidation of Soviet power. [3]

6. (a) Simply declaring one source “more reliable” and dismissing the other, without explaining why. [1] (b) A better approach explains the apparent contradiction by considering each source’s origin and purpose — for example, a source produced by a political party with an interest in presenting events a particular way may differ from a private, unpublished account with less incentive to promote a specific narrative — and explains how these different origins and purposes plausibly account for the disagreement, rather than treating one source as simply correct and the other as simply wrong. [3]

7. Paper 2 is document-based, meaning it presents historical sources and asks candidates to interpret, evaluate and cross-reference them against a specific question, rather than testing recall of a narrative sequence of events directly. This means Depth Study preparation must include deliberate practice interpreting a range of source types (photographs, posters, cartoons, official documents, personal accounts) and evaluating their origin, purpose and value as evidence, alongside — not instead of — building genuine factual knowledge of the period, since Paper 2’s questions expect sources to be assessed against secure background knowledge, not treated as a substitute for it. The Core Content options, by contrast, are examined through a broader survey-style approach that rewards narrative and explanatory knowledge more directly, without the same specific demand for source-evaluation technique. [6]

8. This reasoning is weak, because although the Second World War was indeed a single global conflict, the syllabus specifically frames Depth Study E as covering “Europe and the Asia-Pacific” as related but distinct theatres, each with its own specific causes, course and consequences that a candidate is expected to know. Preparing only the European theatre risks being unable to answer a source-based question set specifically on the Asia-Pacific theatre, or a question asking candidates to draw connections between the two theatres (such as how events in Europe affected Japan’s strategic calculations), which requires genuine knowledge of both sides rather than one theatre extended by assumption to cover the other. A stronger revision approach prepares both theatres, even if one receives more detailed attention than the other, precisely because “one war” does not mean the exam treats both theatres as interchangeable in its questions. [6] (Marks for correctly identifying the flaw in the student’s reasoning and explaining the syllabus’s actual expectation.)
