Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: by and within living things
Concept:

Prior to 1828, the prevailing scientific dogma was the "Vital Force Theory" (Vitalism) proposed by Jöns Jacob Berzelius.

Solution:

  • Because early chemists could not synthesize organic molecules in the lab, they theorized that organic compounds required a mysterious, non-physical "vital force" to be created.


  • They believed this vital force only existed within living organisms (plants and animals).


  • This theory was completely dismantled when Wöhler synthesized urea from inorganic materials in a lab.


Why other options are incorrect:

The limitation was philosophical and biological in their minds, not related to temperature, pressure, or the purity of reagents.

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.
