Answer
Correct Answer: B
Explanation
Introduction / Context:Combine two local orderings into a single consistent left-to-right arrangement, then pick the central seat.
Given Data / Assumptions:
- A left of B and right of C ⇒ C < A < B.
- D right of B and left of E ⇒ B < D < E.
- Five distinct people: C, A, B, D, E.
Concept / Approach:Chain the inequalities into one sequence.
Step-by-Step Solution:
From C < A < B and B < D < E ⇒ C < A < B < D < E.With five seats, the middle is the 3rd position, which is B in the sequence.Verification / Alternative check:Any deviation would break one of the two given local orders.
Why Other Options Are Wrong:C and A are left of the middle; D and E are right of it.
Common Pitfalls:Placing D to the left of B or A to the right of B contradicts the clues.
Final Answer:B
