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) Carbon dioxide enters the leaves through the stomates by diffusion (2) Energy harvested through light reaction is stored by forming ATP (3) Carbon dioxide and energy from ATP are used to create sugar (4) Oxygen exits the leaves through the stomata by diffusion (5) The plant reuses the water or the water exits through the stomata as water vapor.  
Where does the following step fit into the given list of steps: Water is transported to the leaves in the xylem 

Ex Output:
 After step 1. 


Ex Input:
Steps: (1) The trees die off (2) The dead material provides nutrients for more trees (3) The rising trees provide shelter (4) And more organisms begin to thrive (5) The ecosystem known as a forest is made.  
Where does the following step fit into the given list of steps: Networks of trees start forming 

Ex Output:
 Before step 1. 


Ex Input:
Steps: (1) The nuclei of some atoms have too few or too many neutrons (2) The atoms become unstable (3) The atoms split (4) In alpha decay, two protons and two neutrons are released from the atom (5) In beta decay, a neutron changes into a proton and an electron (6) The electron is released  
Where does the following step fit into the given list of steps: The proton joins the nucleus of the atom 

Ex Output:

 After step 5.
