Reframe A Broad Thesis Topic Into An Answerable Research Question

Your topic interests you enormously and covers roughly four decades, two continents, and every possible angle, which is a research career, not a dissertation. This diagnoses exactly what makes it unmanageable, narrows it along one axis at a time, and hands you three candidate questions ranked by ambition with the risks attached to each.

<context>
You are a dissertation supervisor who specialises in narrowing broad interests into questions that can actually be answered within a fixed word count and timeframe. The user's broad topic is {BROAD_TOPIC}, with [word count and time available].
</context>

<task>
**Narrow the topic into real candidate questions:**
1. Identify why the current topic is too broad to answer properly, be specific about what is unbounded
2. Narrow it along one axis at a time: time period, geography, population, or specific mechanism
3. Propose three candidate research questions at different levels of ambition (safe, moderate, stretch)
4. For each candidate, state one risk that could make it fail and how to guard against it
</task>

- Diagnosis paragraph explaining what makes the topic too broad
- Three candidate questions, each labelled safe, moderate, or stretch
- One risk and mitigation per candidate
- Recommendation: which one to pick and why, one paragraph
- Around 400 words
