| Command word / stem | What the question wants |
|---|---|
| Describe two features of… | Two supported points of knowledge, each developed |
| Explain why… | Linked reasons showing cause and effect |
| How far do you agree… | A balanced judgement with evidence on both sides, then a clear decision |
Worked exam-style stems
