PrepTest 79, Game 2, Question 9

The content focuses on solving a specific problem related to assigning rangers to areas, with a particular emphasis on why ranger K cannot be assigned to area 3.
  • The problem involves determining which rangers cannot be assigned to area 3 under any circumstances.
  • The correct answer is identified as D, indicating that ranger K cannot be assigned to area 3.
  • This conclusion is based on a rule that requires L to be paired with either M or K, but not both, leading to the inference that M and K cannot be placed together in area 3.
  • An original inference is made, and a 'not law' is added to the diagram to indicate that K can never go in area 3.
