About this paper
Sir Adnan's 'PMS 2026 TRICKY GK' booklet (4 pp, header 'ONE-LINER (PPSC/FPSC NEW TREND 2025-26)') from the monster-data 'PMS SCREENING 2026 GK UPDATED' pack. 39 of 41 printed items published (1 dropped: printed Q34, phenology as 'the study of migration of birds' - phenology is the study of the seasonal timing of life-cycle events generally, so the booklet's narrow answer is not a standard fact; 1 cross-linked: printed Q32, pangolin order, already published identically in the mammalian-orders practice set). The set is published in the standard format with authored distractors under the 2026-10-28 single-format decision; note flags cover the Stephenson/Trevithick locomotive credit, the carbon monoxide in coal gas, and Mercury's tenuous exosphere. The stainless-steel item (Q20) is kept despite a high stem similarity to a 'steel is an alloy of' item elsewhere: it asks a different alloy with a different answer.

39 solved MCQs shown directly below
Correct Answer: Rickets
Vitamin D is needed for calcium absorption and bone mineralisation; its deficiency in children causes rickets (soft, weak bones).
Correct Answer: 1614
John Napier published his description of logarithms in 1614 (Mirifici Logarithmorum Canonis Descriptio).
Correct Answer: Iodine
Iodine is needed to make thyroid hormones; iodine deficiency enlarges the thyroid gland, causing goitre.
Correct Answer: Isaac Newton
Isaac Newton formulated the law of universal gravitation: every mass attracts every other mass.
Correct Answer: 33
The human vertebral column has 33 vertebrae in total, including the fused vertebrae of the sacrum and coccyx.
Correct Answer: Paper
Paper is made from wood pulp; glass, steel and plastic are not wood products.
Correct Answer: Elongation of eyeball
In myopia the eyeball is too long, so distant images focus in front of the retina instead of on it.
Correct Answer: Eucalyptus
Eucalyptus species are among the fastest-growing trees, which is why they are widely planted for timber and pulp.
Correct Answer: Habitat destruction
Habitat destruction is the largest single driver of biodiversity loss, ahead of climate change, pollution and overhunting.
Correct Answer: Acid
An acid releases hydrogen ions (H+) in water; bases release hydroxide ions instead.
Correct Answer: Deosai Plains
The Deosai Plains, at over 4,000 metres in Gilgit-Baltistan, are Pakistan's highest plateau.
Correct Answer: 343 m/s
Sound travels at about 343 metres per second in air at around 20 degrees Celsius.
Correct Answer: Location of objects on Earth
The Global Positioning System gives the location of a receiver or object on Earth using satellite signals.
Correct Answer: Ibn al-Haytham
Ibn al-Haytham's Book of Optics laid out the laws of reflection and refraction of light.
Correct Answer: George Stephenson
George Stephenson is the booklet's standard answer; his Rocket (1829) made steam railways practical.
Correct Answer: 1931
The Gandhi-Irwin Pact was signed on 5 March 1931 between Mahatma Gandhi and Viceroy Lord Irwin.
Correct Answer: Helium
Modern balloons use helium because it is lighter than air and, unlike hydrogen, non-flammable.
Correct Answer: Isaac Newton
Newton's three laws of motion (inertia, force equals mass times acceleration, and action-reaction) were published in 1687.
Correct Answer: Radiation
Solar heat crosses the vacuum of space as radiation; conduction and convection need a material medium.
Correct Answer: Iron, Chromium and Nickel
Stainless steel is mainly iron with chromium (which resists rust) and nickel; iron and carbon alone make ordinary steel.
Correct Answer: Virus (H5N1)
Bird flu is a viral disease caused by influenza A viruses such as H5N1.
Correct Answer: Methane and Hydrogen
Coal gas is mainly hydrogen and methane, the two combustible gases the booklet names.
Correct Answer: Leukemia
Ionising radiation such as X-rays and gamma rays can damage blood-forming cells and cause leukaemia, a cancer of the blood.
Correct Answer: Decomposers
Bacteria and fungi break down dead organic matter, so in food chains they are decomposers.
Correct Answer: All of these
A vacuum flask cuts all three routes: the vacuum stops conduction and convection, and the shiny walls reflect radiation.
Correct Answer: Game reserve
In Pakistan's protected-area system, hunting is permitted under licence in a game reserve, but not in a wildlife sanctuary or national park.
Correct Answer: Feral
Feral describes domesticated animals (or plants) that have returned to living wild.
Correct Answer: Fats
Fats give about 9 kilocalories per gram, more than double the roughly 4 kilocalories per gram from proteins or carbohydrates.
Correct Answer: Joseph Priestley
Joseph Priestley isolated oxygen in 1774 and is conventionally credited with its discovery.
Correct Answer: Mercury
Mercury is the booklet's standard answer: it has no substantial atmosphere, unlike Venus, Mars or Jupiter.
Correct Answer: Do not absorb heat
White surfaces reflect most sunlight instead of absorbing it, so white clothes stay cooler in summer.
Correct Answer: DNA ligase
During DNA replication, DNA ligase seals the gaps between Okazaki fragments on the lagging strand.
Correct Answer: All proteins in a cell
Proteomics is the large-scale study of the full set of proteins produced by a cell or organism.
Correct Answer: Anthozoa
Reef-building corals belong to the class Anthozoa (flower animals), within the phylum Cnidaria.
Correct Answer: Triassic Period
The first true mammals appear in the Late Triassic, roughly 210 million years ago.
Correct Answer: Sponges
Mesohyl is the gelatinous matrix between the outer and inner cell layers of sponges.
Correct Answer: Horse
Eohippus (Hyracotherium), a small early equid, is the ancestor of the modern horse.
Correct Answer: Pachytene
Crossing over between homologous chromosomes takes place during the pachytene stage of prophase I.
Correct Answer: Psychology
Psychology is the study of the mind and human behaviour, including behaviour in relationships.

Questions
No. It is Sir Adnan's 'PMS 2026 TRICKY GK' one-liner booklet from the monster-data 'PMS SCREENING 2026 GK UPDATED' pack, published as paperType 'practice', never as a past paper. The year 2026 is the booklet's label, not a claimed exam session.
Tricky one-paper general knowledge: vitamin deficiency and disease, Napier's logarithms, Newton's gravity and laws of motion, sound and light, stainless steel and coal gas, biodiversity and decomposers, the human spine and myopia, and biology from pangolins and proteomics to crossing over in meiosis.
Printed Q34 was dropped, never rewritten: it presents phenology as the study of bird migration alone, but phenology is the study of the seasonal timing of life-cycle events in plants and animals generally (flowering, migration, breeding), so the booklet's narrow answer is not a verifiable standard fact. Printed Q32 (pangolin order) was cross-linked, not re-extracted, because it is already published identically in the mammalian-orders practice set.
Yes. Every published item carries an explanation, and three items carry note flags: the steam-locomotive credit (Trevithick 1804 first, Stephenson's Rocket 1829 made it practical), coal gas also containing carbon monoxide, and Mercury's extremely tenuous exosphere behind the school answer of 'no atmosphere'.
