Step-by-step explanation:
Based on the description given in the passage, the author's word choice creates a sense of barrenness. The references to the scarcely furnished flat and the dysfunctional letter box and electric button convey a feeling of dreariness and lack, thus suggesting barrenness. The words used do not evoke hopefulness, romance or mystery. Rather, they paint a picture of a desolate and lifeless scene, implying a distinct sense of emptiness or barrenness. For instance, the term vestibule, which refers to a small entryway within a building, literally describes a space, but also metaphorically suggests a sense of emptiness or lack of warmth.
