The rising actions of the story “There Will Come Soft Rains” would start from the point when the house, a quite ultra-modern, high-tech one, had started to function at 7:00 a.m. just like any ordinary day but no one moved (“The clock ticked on, repeating and repeating its sounds into the emptiness”) up to the point where it says “The house stood alone in a city or rubble and ashes”. As the house’s technologically-orchestrated buttons and machines worked their way automatically, the readers come to realize that there is something terribly wrong in this house.
The climax would be the part when the city is described as completely destroyed and giving off a “radioactive glow which could be seen for miles”. Also, the readers would feel really devastated when it was described that there were “five spots of paint – the man, the woman, the children, the ball – remained. The rest was a thin charcoal layer.”
All the events following the climax --- the dog whimpering and eventually dying, the nursery getting ready for the children but eventually dissolving, to the bath filling up with water and an automated poem-reader that nobody listened to---are what would be considered the falling action.
It is obvious that the house burst into flames and became ashes.
