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.
Input: Steps: (1) The human body takes a breath inward (2) Air is transported to the lungs (3) Air reaches the alveoli, the smallest air sacs in the lungs (4) In the alveoli, air passes into the blood within small capillaries (5) The gaseous oxygen in the air dissolves into the capillary blood (6) The dissolved oxygen is picked-up by red blood cells (7) Red blood cells circulate throughout the body and reach the various tissues (8) Within small capillaries, the heme release the oxygen (9) The oxygen can then reach the cells within the tissue
Where does the following step fit into the given list of steps: The red blood cells bind the oxygen via a protein called heme
Output:
After step 6.
