Propolis Cognitive Error Autopsy

Official Correct Choice:

Solution:

  • Only a straight line provides a constant slope.


Why other options are incorrect:

Curves imply changing acceleration.

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.
