To make the plot linear, we need to arrange the events in sequential order based on the timeline of events. The key is to organize the actions so that they logically follow one another.
The original order is: 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. D. While Marla is eating breakfast, her little sister finds Marla's work shoes in the bedroom closet and walks away in them.
If we move D to the beginning, the events would be:
- While Marla is eating breakfast, her little sister finds Marla's work shoes in the bedroom closet and walks away in them.
- After she finishes breakfast, Marla rummages through her bedroom closet looking for her work shoes.
- Marla can't find her work shoes, so she pulls on a pair of slippers.
- Marla runs to the bus stop in her slippers and gets on the bus to work.
This arrangement makes the plot linear, as it establishes the cause (the sister taking the shoes) before Marla's actions.
Therefore, the correct answer is: Move D to the beginning.
