Difficulty: Medium
Correct Answer: Cannot be determined
Explanation:
Introduction / Context:Height-order questions often yield a full chain, but sometimes the data underdetermine the extremes. Here we must decide the shortest person using two mini-chains that do not fully connect all five individuals.
Given Data / Assumptions:
Concept / Approach:Combine the chains where possible: Raina is above Dhoni; Dhoni is above both Virat and Rohit; Rohit is above Shikhar. We know Shikhar is below Rohit, and Virat is below Dhoni, but we lack Virat vs. Shikhar relation.
Step-by-Step Solution:
Chain 1: Raina > Dhoni > Virat.Chain 2: Dhoni > Rohit > Shikhar.Merge around Dhoni: Raina > Dhoni > (Virat and Rohit ...), with Rohit > Shikhar. But Virat vs. Shikhar is unknown.Hence the shortest could be Shikhar (if Shikhar < Virat) or Virat (if Virat < Shikhar). Both orders fit the clues.Verification / Alternative check:Construct two consistent examples: (a) Make Virat 170 cm and Shikhar 168 cm ⇒ Shikhar shortest; (b) Make Virat 165 cm and Shikhar 168 cm ⇒ Virat shortest. All constraints remain satisfied in both scenarios.
Why Other Options Are Wrong:
Common Pitfalls:Forcing a total order when the data allow multiple valid arrangements. Always check if a missing comparison exists.
Final Answer:Cannot be determined
