The Red Scare and McCarthyism in exam wording
| 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
- “Describe two features of the work of HUAC.” Give one feature with a supporting detail, then a second feature with its own detail — two developed points, no narrative.
- “Explain why fear of communism spread through the USA after 1945.” Build two or three linked reasons into a chain of cause and effect. Reward: developed causation, not a list.
