In the short story "There Will Come Soft Rains," if you were to think back to the story in the days and weeks to come, what image do you think will...

In terms of broad geographical perspective, the image that stands out is of this one remaining house amidst a city that has been destroyed. The house is the only one left, and is surrounded by rubble. From a distance, the city (what is left of it) glows from the radioactivity caused by the bomb. This is an apocalyptic image and suggests how technology (atomic bombs) can destroy civilization:

In terms of broad geographical perspective, the image that stands out is of this one remaining house amidst a city that has been destroyed. The house is the only one left, and is surrounded by rubble. From a distance, the city (what is left of it) glows from the radioactivity caused by the bomb. This is an apocalyptic image and suggests how technology (atomic bombs) can destroy civilization: 

The house stood alone in a city of rubble and ashes. This was the one house left standing. At night the ruined city gave off a radioactive glow which could be seen for miles. 

Another striking image is described in the next paragraph. The family had been outside during the blast. They were destroyed but the blast left white silhouettes on the western side of the house. This gives a poetic yet morbid image of what was left of these people. The silhouettes are like anonymous tombstones, the only remains of the family: 

The entire west face of the house was black, save for five places. Here the silhouette in paint of a man mowing a lawn. Here, as in a photograph, a woman bent to pick flowers. Still farther over, their images burned on wood in one titanic instant, a small boy, hands flung into the air; higher up, the image of a thrown ball, and opposite him a girl, hands raised to catch a ball which never came down. 

There is also the morbid image of the robotic mice carrying the dead dog away. And there is the final image of the one remaining wall of the house after the rest has burned to the ground: 

Dawn showed faintly in the east. Among the ruins, one wall stood alone. Within the wall, a last voice said, over and over again and again, even as the sun rose to shine upon the heaped rubble and steam: "Today is August 5, 2026, today is August 5, 2026, today is…" 

Even though the family had been gone prior to the start of the story, the devastation feels more complete and more lonely with just one wall remaining. And the last remaining voice announcing the date, even though it is robotic, seems more lonely as well.
