Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: 3
Concept:

Periodic sequences repeat in modular arithmetic cycles. The element at position \(N\) corresponds to \(N \pmod T\), where \(T\) is the period.

Formula / Rule / Reaction:

$$\text{Periodic Index} = N \pmod T \quad (T = 3)$$

Solution:

  • The repeating pattern consists of 3 distinct images: Box 1 (Circle), Box 2 (Cross), Box 3 (Triangle).


  • For Box 12: \(12 \pmod 3 = 0\), which maps directly to the 3rd image of the cycle (Triangle).


  • Therefore, Box 12 matches Image 3 (Option C).


Why other options are incorrect:

  • Option A (Image 1): Corresponds to \(N \equiv 1 \pmod 3\) (Boxes 1, 4, 7, 10, 13).
  • Option B (Image 2): Corresponds to \(N \equiv 2 \pmod 3\) (Boxes 2, 5, 8, 11, 14).
  • Option D (Image 4): Not part of the repeating sequence.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
