Can you provide some examples of the trolley problem?

The trolley problem is a moral dilemma that involves a choice between sacrificing one person to save many others. One example is the classic scenario where a trolley is headed towards five people tied to the tracks, and you can divert the trolley to a different track where it will only hit one person. Another example is the footbridge scenario, where you can push a person off a bridge to stop the trolley and save five others.
