To make the plot linear, one effective change would be to move D to the beginning. This way, the sequence of events would flow in a chronological order, beginning with the action of Marla's sister finding the shoes before Marla's subsequent actions. The revised order would be:
- D. While Marla is eating breakfast, her little sister finds Marla’s work shoes in the bedroom closet and walks away in them.
- A. After she finishes breakfast, Marla rummages through her bedroom closet looking for her work shoes.
- B. Marla can’t find her work shoes, so she pulls on a pair of slippers.
- C. Marla runs to the bus stop in her slippers and gets on the bus to work.
This order maintains a logical progression of events.
