1.Jana leaves her truck's motor running while she enters a Kwik-Pik Store. The truck's transmission engages, and the vehicle crashes into a gas pump, starting a fire that spreads to a warehouse on the next block. The warehouse collapses, causing its billboard to fall and injure Lou, a bystander. Can Lou recover from Jana? Why or why not? (See Unintentional TortsNegligence.)

2.A water pipe bursts, flooding a Metal Fabrication Company utility room and tripping the circuit breakers on a panel in the room. Metal Fabrication contacts Nouri, a licensed electrician with five years' experience, to check the damage and turn the breakers back on. Without testing for short circuits, which Nouri knows that he should do, he tries to switch on a breaker. He is electrocuted, and his wife sues Metal Fabrication for damages, alleging negligence. What might the firm successfully claim in defense? (See Defenses to Negligence.)
