Synthesising and evaluating information to test a hypothesis

Introduction: Tackling the "Big Question"

Welcome! You’ve reached the final hurdle of Paper 1, Section A. The "Synthesising and Evaluating" question is often the most daunting because it carries the most marks (12 marks) and requires you to look at the "big picture."

In this chapter, we will learn how to take multiple sources—some that agree and some that disagree—and use them to test a specific hypothesis (a statement or theory). Think of yourself as a judge in a courtroom: you aren't just listening to one witness; you are looking at all the evidence, weighing its quality, and deciding what the "truth" likely is.

Don’t worry if this seems like a lot to juggle. We will break it down into a clear, step-by-step process that works for any Key Issue, whether it's about State-Owned Enterprises (SOEs), political stability, or China-US relations.

Section 1: What is a Hypothesis?

In the context of your exam, a hypothesis is a statement provided in Question 1(d). It usually takes a stand on a contemporary Chinese issue.

Example Hypothesis: "China’s transition to a green economy has been largely successful."

Your job isn't just to say "Yes" or "No." Your job is to test it using the five sources provided in Section A. You must determine the degree to which the evidence supports that statement.

Section 2: The Three Pillars of Your Answer

To score high marks, your answer needs three main ingredients:

1. Synthesis (The Jigsaw Puzzle)

Synthesis means combining information from different sources to support a common point. Instead of writing a paragraph for Source A, then a paragraph for Source B, you should group them.
Example: "Both Source A and Source C suggest that urbanisation has placed a strain on social services, though Source C focuses specifically on the hukou system."

2. Evaluation (The Reality Check)

You shouldn't take every source at face value. Evaluation involves asking: How reliable is this? Does the author have a bias? Is the information limited? You use the skills you learned in the "Assessing Strengths and Limitations" chapter to decide how much weight to give a source when testing the hypothesis.

3. Testing (The Final Verdict)

This is your conclusion. Based on your synthesis and evaluation, how far is the hypothesis true? Is it "mostly true," "true only in certain regions," or "true in the short term but not the long term"?

Section 3: Step-by-Step Guide to Success

Step 1: Categorise Your Sources

As soon as you read the hypothesis, go through your five sources and mark them:

• (+) Support: This source agrees with the hypothesis.
• (–) Challenge: This source disagrees or provides a different perspective.
• (+/–) Both: This source has evidence for both sides.

Step 2: Building the "Support" Case

Start by grouping the sources that agree with the hypothesis. Use phrases like: "Sources A, B, and E collectively support the view that..." or "Source B reinforces the data in Source A by showing..."

Step 3: Building the "Challenge" Case

Now, look at the other side. This shows the examiner you are thinking critically. "However, Sources C and D suggest a more complex reality, highlighting that..."

Step 4: Evaluate the Evidence

While you are discussing the sources, add your evaluation. If a source is a government press release, it might be ideological and paint a very positive picture of political stability. If a source is an NGO report, it might focus more on the challenges of social inequality. Mentioning this helps you decide which side of the argument is stronger.

Step 5: Reach a Conclusion

End with a clear judgement. Use "The Weight of Evidence" approach: "While Sources A and B provide strong statistical evidence of economic growth, the qualitative concerns raised in Sources C and D regarding environmental degradation suggest that the hypothesis is only partially accurate."

Section 4: Common Mistakes to Avoid

1. The "Shopping List" Approach: This is the most common mistake. Students write "Source A says X. Source B says Y. Source C says Z." This is not synthesis. You must show how they relate to each other.

2. Ignoring the Hypothesis: Don't just talk about China in general. Every sentence should help you decide if the hypothesis is true or false.

3. Forgetting Contextual Knowledge: While you must use the sources, you are also expected to bring in your own understanding of contemporary China (2000–present) to help explain why a source might be saying something.

Section 5: Quick Review & Key Takeaways

Quick Review Box:

• Q1(d) Weight: 12 marks.
• Goal: Use all 5 sources to test the given statement.
• Structure: Introduction -> Points for -> Points against (with evaluation) -> Conclusion.
• Keywords: Always use the "command language" from the syllabus: Synthesise, Evaluate, Test, Degree to which.

Key Takeaway: Success in this chapter is about balance. A student who can show that "Source A is strong because of its data, but Source B adds a necessary human perspective that Source A ignores" is a student who will get an A!
