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) Boil salt water (2) The water will turn into water vapor (3) Collect the water vapor (4) The water vapor will turn into liquid water (5) The salt will be separated from the water.  
Where does the following step fit into the given list of steps: Allow the water vapor to cool 

SOLUTION:  After step 3. 

PROBLEM: Steps: (1) The saliva breaks down the chemicals in the food a bit, which helps make the food mushy and easy to swallow (2) Your tongue helps out, pushing the food around while you chew with your teeth (3) The esophagus moves food from the back of your throat to your stomach (4) Strong muscles in the walls of the stomach and gastric juices break down food in your stomach  
Where does the following step fit into the given list of steps: Your stomach moves the food into the intestines to complete digestion 

SOLUTION:  After step 4. 

PROBLEM: Steps: (1) When water freezes it becomes 10% bigger, or takes up 10% more space (2) The force of the pressure exerted on the rock surrounding it is enough to wedge the walls of the crack farther apart, thus expanding and deepening the crack (3) Clay expends when wet like ice does (4) This causes rock to break apart (5) Some plants like mosses and lichens are capable of growing without soil on bare rock (6) When they do this their roots penetrate pores and crevices and cause rocks to split apart as the roots force their way down through the rocks  
Where does the following step fit into the given list of steps: As water expands it puts great pressure on the walls of anything containing it, including any rocks which happen to be surrounding it 

SOLUTION:
 After step 1.
