Introduction: Mastering the "Big" Question

Welcome! If you are preparing for the GCE A-Level History (9174) exam, you already know that the Source-Based Case Study (SBCS) is a major part of your grade. Specifically, Sub-question (b) is the "heavyweight" of the paper. It is worth 30 marks (15% of your total grade) and asks you to test a specific assertion (a statement or claim) against a set of sources.

Think of yourself as a judge in a courtroom. You aren't just reading stories; you are weighing evidence to see if a specific claim holds up. Whether the topic is the Cold War (Paper 1) or Regional Conflicts in Southeast Asia (Paper 2), the skills you need for this question remain exactly the same. Don't worry if it feels overwhelming—we will break it down step-by-step!

1. What exactly is an "Assertion"?

An assertion is a statement provided in the question that takes a stand on a historical issue. For example:

"How far do these sources support the view that the USA was primarily responsible for the outbreak of the Cold War?"

In this case, the assertion is: The USA was primarily responsible for the Cold War.

Your job is to use all the sources provided (usually up to six) and your contextual knowledge to argue how far that statement is true.

2. The "Both Sides" Strategy

To score well, you cannot just agree with the assertion. History is rarely one-sided! You must show balance. This means you need to categorize your sources into two groups:

  • Support: Sources that agree with the assertion.
  • Challenge: Sources that disagree or offer an alternative explanation.

Pro-tip: Some sources might be "nuanced." They might support the assertion in one way but challenge it in another. Recognizing this complexity is a hallmark of a high-level student!

3. Using the Sources as Evidence (AO3)

When you use a source, don't just quote it. You must interpret it. Ask yourself:

  • What is the main point of this source?
  • How does this point relate to the assertion?
  • Does the source's provenance (who wrote it, when, and why) make it more or less convincing?

Note: For more details on checking reliability, see the chapter on "Provenance, purpose and audience."

4. The Role of Contextual Knowledge (AO1)

The syllabus (9174) explicitly states that you must use background knowledge of the issues to test the assertion. You shouldn't just "dump" facts; instead, use your knowledge to:

  1. Explain the Source: Use facts to explain why a source is saying what it's saying. (e.g., "Source A reflects the Traditional view of the Cold War because at the time...")
  2. Verify the Source: Use facts to check if what the source says is actually true.
  3. Fill the Gaps: Mention important events or perspectives that the sources might have missed.

Quick Review: The Assessment Objectives

AO1: Using your historical knowledge (the facts you studied about the Cold War or SE Asia).
AO3: Analysing and evaluating the sources themselves.

5. Step-by-Step Execution Plan

Don't worry if this seems tricky at first; follow these five steps for a clear, logical answer:

Step 1: Analyse the Assertion
Highlight the key terms in the question. What is the specific "claim" you are testing?

Step 2: Group the Sources
Quickly jot down which sources Support (S) and which Challenge (C). You must use ALL sources to reach the highest marks.

Step 3: Write the Supporting Paragraph(s)
Group sources that agree. "Sources A, C, and E support the assertion that... because Source A shows... and Source C further illustrates..."

Step 4: Write the Challenging Paragraph(s)
Group sources that disagree. "On the other hand, Sources B, D, and F challenge this view by suggesting that..."

Step 5: The Final Judgement (Conclusion)
This is where you earn the top marks. Don't just repeat yourself. Reach a reasoned conclusion. Is the assertion mostly true, partially true, or largely inaccurate? Why?

6. Common Mistakes to Avoid

  • The "Laundry List": Avoid writing "Source A says this. Source B says that. Source C says this." This is too descriptive. Instead, group them by their argument.
  • Ignoring the "How Far": The question asks "How far." If you only provide one side of the argument, you are not answering the question.
  • Forgetting Context: If you don't use your own knowledge (AO1), your marks will be capped. Remember, this is a History exam, not an English Comprehension test!
  • Treating Sources as "Facts": Remember that sources are interpretations. A political cartoon or a speech by a leader (like Gorbachev or Lee Kuan Yew) has a purpose and a bias.

7. Summary Checklist for Success

Before you finish your practice or exam paper, ask yourself:

  • Did I use every single source provided?
  • Did I present a balanced argument (both support and challenge)?
  • Did I bring in outside knowledge to explain or check the sources?
  • Did I evaluate the reliability or weight of the evidence?
  • Did I provide a clear final judgement in the conclusion?
Key Takeaway

Sub-question (b) is about weighting evidence. It is a 30-mark exercise in balance. Use all your sources, sprinkle in your historical knowledge, and always remember that in history, there is rarely just one "right" answer—there are only well-supported arguments!

Remember: This specific skill applies to Paper 1 (Theme I: Development of the Cold War) and Paper 2 (Theme III: Regional Conflicts and Cooperation). Mastering this chapter is the key to passing the SBCS section of the 9174 syllabus.
