Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Option C
Concept:

Spatial Pattern Invariance and Periodic Sequence Interleaving.

Rule:

$$\text{Sequence: } [\text{Triangle}] \rightarrow [\text{Rectangle}] \rightarrow [\text{Rectangle}] \rightarrow [\text{Triangle}] \rightarrow \dots$$

Solution:

  • The repeating motif requires exactly two intervening rectangles between successive triangular delimiter nodes: ▲ ■ ■ ▲ ■ [ ? ] ▲.
  • After the triangle at position 4, position 5 is a rectangle. Therefore, position 6 must also be a Rectangle (Option C) to complete the pair before the next triangle.


Why other options are incorrect:

  • Option A (Triangle): Would place two consecutive triangles, breaking the sequence rule.
  • Option B (Circle) & Option D (Diamond): Geometric shapes foreign to this two-symbol alternating 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.
