TASK DEFINITION: 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.
PROBLEM: Steps: (1) Networks of trees start forming (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: The trees die off 

SOLUTION:  After step 1. 

PROBLEM: Steps: (1) Waves hit the coast (2) Waves have energy that pushes the water and sediment (3) The sediment can help erode land like sandpaper (4) Water washes the sediment back  
Where does the following step fit into the given list of steps: Some sediment is left as sand. 

SOLUTION:  After step 4. 

PROBLEM: Steps: (1) Human beings burn fossil fuels (oil, gas, etc.) (2) The make-up of the atmosphere changes (3) Some energy from the sun cannot escape back through the changed atmosphere (4) The earth begins to heat because of the extra trapped energy (5) Human beings cut down trees (6) Human beings do not re-plant the trees (7) Trees cannot help take the extra carbon dioxide from the atmosphere (8) The extra trapped energy starts to change the earth&#x27;s short term weather (9) Eventually the long-term climate patterns start to change  
Where does the following step fit into the given list of steps: Carbon dioxide from the burning fossil fuels enter the atmosphere 

SOLUTION:
 After step 1.
