The best response that shows how the historical setting contributes to the effect of personification in the passage is:
“and in the drone of the aeroplane the voice of the summer sky murmured its fierce soul.” This expresses the sound of a plane of that time period.
Explanation: This evidence illustrates how the introduction of technology, such as the aeroplane, interacts with the natural environment, personifying the sky and imbuing it with emotions ("murmured its fierce soul"). The historical context of early aviation adds depth to the personification, as it highlights the contrast between nature and modernity, enriching the reader's understanding of the setting.
