Six people D, E, F, G, H and I are sitting in a straight row, facing north. Only two people sit to the right of H. Only four people sit between I and G. D sits third to the left of E. I is not an immediate neighbor of E. Who sits at the extreme right end of the row?

Explanation

• The condition 'Only two people sit to the right of H' fixes H's position at the 4th spot from the left.
• The condition 'Only four people sit between I and G' means I and G must occupy the extreme ends (positions 1 and 6).
• The clue 'D sits third to the left of E' places D at position 2 and E at position 5.
• The final constraint 'I is not an immediate neighbor of E' eliminates the possibility of I being at the right end, forcing G to be at the right end.
• Combining all clues, the only valid sequence is I-D-F-H-E-G, placing G at the extreme right end.

Why Other Options Were Wrong

• Option A: Based on the derived arrangement, E sits at the 5th position, which is second from the right end, not at the extreme right.
• Option C: F occupies the 3rd position from the left, which is in the middle of the row, not at an end.
• Option D: I sits at the extreme left end (position 1). The constraint that I cannot be a neighbor of E is what forces I to the left end.

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Logical Reasoning - Linear Seating Arrangement as background academic context rather than a clinical decision trigger.
• Logical and analytical reasoning are fundamental skills for nurses, essential for effective time management and task prioritization in a busy clinical setting.
• Nurses use these skills to organize patient care schedules, manage medication administration times, and allocate resources efficiently based on multiple competing needs and constraints.
• What if? - If the clue was 'D sits third to the right of E' instead, the entire arrangement would change, highlighting how a single detail can alter the outcome, similar to how a change in a patient's vital sign can alter the plan of care.

How to Approach the Question

• First, identify the total number of people and their orientation (e.g., 6 people, facing north).
• Scan the clues for the most definitive piece of information to create a starting anchor. Here, it's H's fixed position.
• Use clues about large gaps or relative positions to place other individuals (e.g., I and G at the ends; D and E's relative placement).
• Formulate possible scenarios or cases based on the clues (e.g., Case A with I on the left, Case B with G on the left).
• Use negative or restrictive clues (e.g., 'I is not an immediate neighbor of E') to eliminate invalid scenarios.
• Once the correct scenario is identified, fill in any remaining individuals to complete the arrangement and answer the specific question.
