Answer

Answer:

burning gasoline in a car engine

Explanation:

Step1: Define self - sustaining reaction

A self - sustaining reaction continues without external intervention once started.

Step2: Analyze hard - boiling an egg

Requires continuous heat input from an external source (stove), not self - sustaining.

Step3: Analyze thrusting a rocket into space

Needs continuous fuel injection and ignition controlled by external systems, not self - sustaining.

Step4: Analyze burning gasoline in a car engine

Once the engine is started, the combustion of gasoline in the cylinders is a self - sustaining cycle as long as there is fuel and air supply. The spark plug ignites the fuel - air mixture initially, and then the expanding gases from combustion push the pistons, which in turn help in the intake and compression of the next fuel - air charge for the next combustion cycle.
