The sentence “under the oppressive sun” indicates the hostile environment of the trip.
We can arrive at this answer because:
- In “Tuesday Siesta” we come across a journey made by a mother and her daughter.
- The trip was very exhausting and difficult, mainly due to the environmental conditions.
- This becomes clear when the narration states that during the journey, the sun was oppressive.
With that, we can say that the sun was emitting energy very strongly, making the environment very hot and difficult to be overcome, which severely jeopardized the trip.
