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.

Steps: (1) The bat sends out sound waves from their mouth or nose (2) Echoes are produced (3) The echo returns to the bat&#x27;s ears (4) The bat hears the echo (5) The bat can figure out where the object is located.

Steps: (1) Acid rain leaches aluminum from clay particles in soil (2) Acid rain dissolves minerals and nutrients in soil (3) Washes them away so plants can&#x27;t benefit from them (4) PH in soil and water gets affected which can kill plants and animals (5) Acid rain in fog at higher elevations can strip foliage off trees.  
Where does the following step fit into the given list of steps: Aluminum flows into streams and lakes 
 After step 1. 

Steps: (1) The flu virus has receptors, which are like viral Velcro, on the surface of the virus particle (2) The receptors will lock onto a target cell using these chemical receptors on the surface, which docks onto the cell surface (3) The receptors  then go into the cell (4) The receptors take it over and make it produce thousands or in some cases millions of copies of new viruses (5) The copies come streaming out of the cell (6) The copies infect other cells to make more viruses, or they escape from the body and infect a new victim  
Where does the following step fit into the given list of steps: The receptors use it like a factory 

 After step 3.
