Question 296 Explanation:
Black Hole: A processing step may have input flows but no output flows.
Miracle: A processing step may have output flows but now input flows.
Grey Hole: A processing step may have outputs that are greater than the sum of its inputs – e.g., its inputs could not produce the output shown.
