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.
Example: Steps: (1) Solar radiation reaches Earth's atmosphere (2) Some is reflected back into space (3) The rest of the energy is absorbed by land and oceans, heating the Earth (4) Some of this heat is trapped by greenhouse gases in the atmosphere (5) Human activities such as burning fuel are increasing the amount of greenhouses gases (6) This causes more heat radiation to stay trapped in our atmosphere (7) The Earth's temperature rises  
Where does the following step fit into the given list of steps: Heat radiates from Earth to space 
Example solution:  After step 3. 
Example explanation: The correct answer is 'After step 3'. The given step is 'Heat radiates from Earth to Space'. Step 3 introduces a new concept of generated heat. Step 4 mentions that the heat is trapped into the atmosphere. In order for the heat to get to the atmosphere, the heat must radiate from Earth to space. Therefore, the correct answer is 'After step 3.'

Problem: Steps: (1) A butterfly lays an egg (2) A larvae matures inside of the egg (3) The caterpillar hatches from the egg (4) The caterpillar spins a coccoon around itself and forms into a pupa (5) The butterfly forms inside of the coccoon (6) The mature butterfly emerges from the coccoon (7) The butterfly mates (8) The female butterfly lays eggs.  
Where does the following step fit into the given list of steps: The caterpillar eats and grows 

Solution:  After step 3.
