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.

Ex Input:
Steps: (1) Living organisms in the sea die (2) The matter forms on the sea floor (3) After many years the matter is compressed and heated (4) The result is that crude oil forms.  
Where does the following step fit into the given list of steps: Layers of sediment form above the matter compressing it 

Ex Output:
 After step 2. 


Ex Input:
Steps: (1) Food is put into mouth (2) Food is chewed and mixed with saliva (spit) (3) Food travels down the esophagus (throat) (4) Food travels into the stomach (5) Acid in the stomach breaks the food down further (6) Food travels into the small intestine (7) Nutrients from food are absorbed into the blood stream (8) Most of the remaining material is now waste (9) The waste is eventually removed from the body.  
Where does the following step fit into the given list of steps: Food travels into the large intestine 

Ex Output:
 After step 7. 


Ex Input:
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&#x27;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&#x27;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&#x27;s wheels through a kind of arm-elbow-shoulder joint called a crank and connecting rod 

Ex Output:

 After step 4.
