No. It is a Sir Adnan mock test headed 'PMS GK General Science Mock Test', prepared for PMS Screening 2026. It is published as paperType 'mock', never as a past paper, and the year 2026 is the booklet's mock label, not a claimed exam session.
Nothing was dropped and no booklet key was corrected: all 100 printed items are published with their keyed answers, each verified as a standard fact. Five close-call items carry NOTE flags explaining the near-option (Q7, Q39, Q88, Q89, Q95).
General science in four strands: discoveries and inventions (scientists and inventors), SI units and measurements, scientific instruments, and laws, theories and systems.
A photometer is the general instrument for measuring light; a lux meter is the photometer that reads illuminance in lux, which is the specific instrument the keyed answer names.
