Narrow a broad medieval-history topic into one focused, answerable research question.
Research writing explains a topic to inform a reader, built from real sources, rather than persuading a reader like last unit's essay did. A broad topic -- "the Silk Road" or "the Black Death" -- is too big for a short report. A good research question narrows that topic to something specific and answerable: not a yes/no question, not something answered in a single sentence, but not so huge it needs a whole book either.
Narrowing a topic works like this: start broad, ask what specifically you want to find out, then test candidate questions against two things -- can this be answered with a few solid sources in a few weeks, and is this genuinely interesting to you? A question that fails either test needs more narrowing, or more widening.
Mastery looks like: They narrow a broad medieval-history topic into one specific, answerable research question that is neither yes/no nor too large for a short report.
Common stumbles: Choosing a question that is really a whole book's worth of topic; choosing one that is a simple factual lookup with no real "how" or "why" to explore.
