You’re standing on a street corner and a pregnant mother and her three children hit a train overpass. The family’s life is in jeopardy, but so also are the people on the train (a group of school children headed to the museum for the day). On either corner of the train there are two buildings who are doomed if the train, which is destined to be derailed, crashes. One building is the Town Hall and is filled with community leaders (politicians, mothers, fathers, youth program leaders). The other is a research hospital for the elderly, filled with the town’s most accomplished geriatric doctors and nurses. You have the ability to save one of the four: the family, the train, the town hall, or the hospital.
