The following is a rough draft of a student report. It contains errors. (1) The engines of the rocket generate hot gases that fire backward. (2) Rockets work on the principle of action and reaction, which is also known as Newton's third law of motion. (3) Most of the rocket's fuel is used up in this initial stage during which an escape velocity is generated. (4) An equal reaction is produced, and the rocket is pushed into space. (5) This escape velocity is required for the rocket to defy gravity and reach outer space.

What is the most appropriate order of the above sentences to provide the best version of the report?
