Narrative sequence: answer How does evidence shape Iran-Iraq War by focusing on Part one: Tensions in the Gulf. Use the chronology of BE Conflict and tension in the Gulf and Afghanistan, 1990-2009, select named evidence connected to Study regional instability, including consequences of the Iran-Iraq War, western and Russian interests in Iran and Iraq, oil-supply threats and Israeli-Palestinian conflict, and order events accurately, show movement from one development to the next, and avoid jumping chronology. End by answering the command word directly.

This exam-style task requires a developed historical argument rather than a list of facts. Begin with the relevant period from Paper 1 Section B: Wider world depth studies, then anchor the answer in Part one: Tensions in the Gulf. The evidence should connect to Study regional instability, including consequences of the Iran-Iraq War, western and Russian interests in Iran and Iraq, oil-supply threats and Israeli-Palestinian conflict and be explained through cause, consequence, change, continuity, significance or interpretation as appropriate. A strong final judgement shows why the selected evidence is more convincing than a vague or unsupported claim.
