Ruth carelessly parks her car on a steep hill, leaving the car in neutral and failing to engage the parking brake. The car rolls down the hill, knocking down an electric line. This sparks from the broken line ignite a grass fire. The fire spreads until it reaches a barn one mile away. The barn houses dynamite and the burning barn explode, causing part of the roof to fall on and injure a passing motorist, Jim. Can Jim recover from Ruth? Why or why not? Please explain fully.
