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) Items are collected (2) The items are sorted (3) Trash is removed from everything else (4) Goes to a landfill (5) The items go into a baler machine for each kind of material (6) The bales are shipped to manufacturers to use to make products.  
Where does the following step fit into the given list of steps: They come out as bales 

Ex Output:
 After step 5. 


Ex Input:
Steps: (1) Air goes into the lungs (2) Oxygen diffuses from alveoli in the lungs to the bloodstream (3) Hemoglobin in red blood cells attaches to the oxygen (4) Red blood cells carry oxygen all around the body (5) Oxygen diffuses into cells from capillaries.  
Where does the following step fit into the given list of steps: The lungs remove oxygen from the air 

Ex Output:
 After step 1. 


Ex Input:
Steps: (1) The human body takes a breath inward (2) Air is transported to the lungs (3) Air reaches the alveoli, the smallest air sacs in the lungs (4) In the alveoli, air passes into the blood within small capillaries (5) The dissolved oxygen is picked-up by red blood cells (6) The red blood cells bind the oxygen via a protein called heme (7) Red blood cells circulate throughout the body and reach the various tissues (8) Within small capillaries, the heme release the oxygen (9) The oxygen can then reach the cells within the tissue  
Where does the following step fit into the given list of steps: The gaseous oxygen in the air dissolves into the capillary blood 

Ex Output:

 After step 4.
