Introduction: Mastering the Comparison Question

Welcome to one of the most important skills in your H2 History toolkit! In both Paper 1 (The Cold War) and Paper 2 (Southeast Asia), the very first question you will encounter in the Source-Based Case Study (SBCS) is sub-question (a). This question asks you to compare two specific sources, and it is worth 10 marks.

Think of yourself as a detective. Two different witnesses are describing the same event, but their stories don't quite match. Your job isn't just to point out where they agree or disagree, but to explain why they have different versions of the truth. Don't worry if it feels overwhelming at first—once you learn the "formula," you'll be able to tackle any pair of sources with confidence!

1. Identifying Similarities and Differences

To compare effectively, you need to look at two layers: Content (what is being said) and Perspective/Tone (how it is being said and the attitude of the author).

Finding Similarities

When looking for similarities, don't just look for the same words. Look for shared points of view or common facts.
Example: If Source A says "The Soviet Union felt threatened by NATO" and Source B says "The USSR viewed Western alliances as a security risk," they similar because both agree that the USSR felt insecure due to Western actions.

Finding Differences

Differences are often more than just "Source A says 'Yes' and Source B says 'No'." They can be differences in emphasis (what they choose to focus on) or interpretation.
Example: On the Konfrontasi (an inter-state tension in Southeast Asia), Source A might blame Indonesian aggression, while Source B might focus on British neo-colonialism as the cause. They disagree on the primary cause of the conflict.

Quick Tip: Always use a Basis of Comparison. This is a common "umbrella" topic that both sources talk about. For example: "Sources A and B differ in their views on the effectiveness of the United Nations in managing the Bosnian War."

2. The "Gold Standard": Explaining the Reasons

To reach the highest marks, you must explain why the sources differ. They aren't just "different" by accident; there is always a reason rooted in the provenance (the background info at the top of the source).

Common Reasons for Differences:

  • Purpose: What is the author trying to achieve? A speech by President Reagan (Reagan Doctrine) intended to rally public support will sound very different from a private Soviet memo discussing economic problems.
  • Audience: Is the source meant for the public or is it a secret document? Authors often "sugar-coat" the truth for public consumption but are more honest in private.
  • Context and Time: When was it written? A source written during the height of the Berlin Blockade (1948) will likely be more hostile than one written during Détente or Gorbachev’s "New Thinking" in the 1980s.
  • Identity/Perspective: An ASEAN member state might view regional cooperation differently than an external superpower like the USA or China.

Key Takeaway: A similarity or difference is what you see; the reason is why the author created the source that way. Always link the reason back to the specific historical context of the syllabus!

3. Step-by-Step Answer Structure

For a 10-mark question, you should aim for a clear, organized response. You can follow this simple "Checklist":

Step 1: The Similarity (Content/Tone)

State one way the sources are similar. Support this by quoting or paraphrasing Source A, then doing the same for Source B. Explain how these quotes prove they share the same view.

Step 2: The Difference (Content/Tone)

State one way the sources are different. Use the Basis of Comparison (e.g., "They differ on the causes of the Cuban Missile Crisis"). Support with evidence from both sources.

Step 3: The Explanation (The "Why")

This is where you evaluate. Use the provenance.
"The reason for this difference is that Source A is a public propaganda poster aimed at boosting morale, whereas Source B is a private diary entry written by a soldier who saw the harsh reality of the conflict."

4. Common Mistakes to Avoid

Don't fall into these "traps" that many students encounter:

  • The "Summary" Trap: Do not just summarize Source A and then summarize Source B. You must link them together in the same paragraph. Use words like "Similarly," "In contrast," or "However."
  • Ignoring the Provenance: Many students forget to look at who wrote the source and when. The small text at the top of the source is your best friend!
  • Lacking Evidence: Always use specific details or brief quotes from the sources to back up your points.
  • Misinterpreting Tone: Pay attention to "loaded" words (e.g., "aggression," "liberation," "tyranny"). These tell you the author's bias.

5. Memory Aid: The "C.A.P." Method

When you are trying to find the reason for a difference, think of C.A.P.:

  1. C - Context: What was happening in the Cold War or Southeast Asia at that exact time?
  2. A - Audience: Who was the author talking to?
  3. P - Purpose: Why did the author bother to say/write this? What was their "end game"?

Note: For more on how to evaluate these specific areas, see the chapter on "Provenance, purpose and audience: evaluating source reliability."

Quick Review

What is the goal? To identify how two sources are the same and how they are different, and then explain the logic behind those differences.
How many marks? 10 marks (5% of your total grade).
What is a "Basis of Comparison"? The specific criteria or topic (e.g., "the role of the USA") that you use to compare the two sources.
Why do sources differ? Because of their different purposes, audiences, and historical contexts.

Don't worry if this seems tricky at first! Like any skill, comparing sources gets much easier with practice. Start by just trying to find one similarity and one difference in every practice paper you do!
