Question 4 · 6 marks
extended responseHow does the writer use language to convey the narrator's growing unease in lines 12–28?
Student answer
The writer uses short sentences like “the door creaked” to make the reader feel the silence pressing in. The repetition of “cold” — first describing the wind, then the corridor, and finally the narrator's hands — builds a sense of creeping dread. The metaphor “the room held its breath” personifies the setting, suggesting that even the building itself is anxious about what might happen next.
AI marking rationale
Olivia identifies two effective language techniques and explains how each builds tension. Strong use of textual evidence. To reach Level 4, the response needs a wider range of techniques and a clearer comment on the cumulative effect on the reader.
