Teacher:Given a list of steps and an additional step, determine where the step fits into the original list of steps. A correct answer, correctly places the given step into the set of steps so that it creates a new plausible set of steps. Output must be formatted as 'After step n', where n is the step number after which the given additional step is to be inserted.
Teacher: Now, understand the problem? Solve this instance: Steps: (1) Coal is loaded into the firebox (2) The boiler produces steam under high pressure (3) The steam generated in the boiler flows down into a cylinder (4) Just ahead of the wheels, pushing a tight-fitting plunger, the piston (5) As the piston pushes, the crank and connecting rod turn the locomotive's wheels and power the train along (6) An outlet valve opens and the piston pushes the steam back through the cylinder and out up the locomotive's chimney
Where does the following step fit into the given list of steps: The piston is connected to one or more of the locomotive's wheels through a kind of arm-elbow-shoulder joint called a crank and connecting rod
Student:
After step 4.
