About this paper
Part 16 (Q751–800) of the Sir Adnan '1000 Advanced Booklet Everyday Science' one-liner compilation (monster-data 'CSS MPT PAST PAPERS' pack). The booklet prints statement + answer only, so each item is published in the standard MCQ format with 3 authored plausible distractors under Anas's 2026-10-28 single-format decision and optionsSource recorded as 'authored'. Only 33 of 50 printed items are published. 17 restate facts already published in earlier parts of the same booklet and are cross-linked, not re-extracted: Q753 largest artery in the human body (Q220 in Q201-250, aorta); Q756 study of earthquakes (Q644 in Q601-650, seismology); Q757 normal human pulse rate (Q223 in Q201-250, 72 beats per minute); Q759 master gland (Q247 in Q201-250, pituitary gland); Q763 organ regulating blood sugar (Q248 in Q201-250, pancreas secreting insulin); Q765 element essential for respiration (Q658 in Q651-700, oxygen as the gas essential for respiration); Q766 largest bone in the human body (Q204 in Q201-250, femur); Q768 element used in pencils (Q137 in Q101-150, graphite); Q772 first antibiotic discovered (Q673 in Q651-700, penicillin); Q774 gas produced by burning coal (Q25 in Q1-50, carbon dioxide from burning fossil fuels); Q776 part of the brain controlling breathing (Q260 in Q251-300, medulla oblongata controlling heartbeat and breathing); Q782 largest cell in the human body (Q276 in Q251-300, ovum); Q790 vitamin preventing rickets (Q230 in Q201-250, vitamin D deficiency causing rickets); Q795 human skull bone count (Q210 in Q201-250, 22 bones); Q796 vitamin necessary for blood clotting (Q225 in Q201-250, vitamin K); Q798 chemical name of chalk (Q149 in Q101-150, calcium carbonate); Q799 blood cells carrying oxygen (Q281 in Q251-300, red blood cells). No printed item in this stretch is dropped as unanswerable and no booklet answer is corrected.

6 solved MCQs shown directly below
Correct Answer: Coulomb
The SI unit of charge is the coulomb: one coulomb is the charge carried by a current of one ampere flowing for one second.
Correct Answer: Volt
The SI unit of voltage is the volt: one volt is the potential difference that drives one ampere through a resistance of one ohm.
Correct Answer: Second
The SI unit of time is the second: the SI base unit, now defined by the caesium-133 atom, with minutes and hours as larger derived units.
Correct Answer: Kelvin
The SI unit of temperature is the kelvin: the SI base unit of thermodynamic temperature, with 0 K (absolute zero) at -273.15°C; Celsius degrees are the same size but counted from water's freezing point.
Correct Answer: Kilogram
The SI unit of mass is the kilogram: the SI base unit of mass, defined since 2019 by the Planck constant; the gram is a thousandth of a kilogram, not the base unit.
Correct Answer: Farad
The SI unit of electric capacitance is the farad: one farad is the capacitance that stores one coulomb of charge at one volt.

9 solved MCQs shown directly below
Correct Answer: Gallium
Gallium is the metal liquid at room temperature besides mercury in the conventional one-liner: it melts at about 29.8°C, just above ordinary room temperature, so a warm hand can melt it.
Correct Answer: Iron
Iron is the main component of steel: steel is iron alloyed with a small amount of carbon (usually under 2%), with chromium and nickel added only in special steels such as stainless steel.
Correct Answer: NH₃
The chemical formula of ammonia is NH₃: one nitrogen atom bonded to three hydrogen atoms, a pungent gas used in fertilizers and refrigeration.
Correct Answer: Nitrous Oxide
Nitrous oxide is the gas used in anesthesia: inhaled with oxygen, it sedates and relieves pain in dentistry and surgery.
Correct Answer: 78°C
The boiling point of alcohol is 78°C: ethanol, the alcohol in drinks and spirits, boils at about 78.4°C, well below water's 100°C, which is why distillation separates them.
Correct Answer: CO + H₂
Water gas is a mixture of carbon monoxide and hydrogen (CO + H₂): it is made by passing steam over red-hot coke and was historically used as a fuel gas.
Correct Answer: Calcium Oxide
The chemical name of quicklime is calcium oxide (CaO): it is made by heating limestone (calcium carbonate), and adding water turns it into slaked lime, calcium hydroxide.
Correct Answer: Na
The chemical symbol of sodium is Na: from its Latin name natrium, not from the English name (K is potassium, Ca calcium, Mg magnesium).
Correct Answer: Neon
Neon is the gas used in fluorescent signs: an electric discharge through neon gives the bright red-orange glow of classic neon signs, while other noble gases give other colours.

Correct Answer: Vitamin B3 (Niacin)
Pellagra is caused by vitamin B3 (niacin) deficiency: its classic signs are dermatitis, diarrhoea and dementia, the 'three Ds'.
Correct Answer: Vitamin C
Vitamin C is found in citrus fruits: oranges, lemons and grapefruit are the classic dietary sources of ascorbic acid, which prevents scurvy.
Correct Answer: Vitamin E
Vitamin E is known as tocopherol: tocopherols are the fat-soluble vitamin E compounds, with alpha-tocopherol the main active form in the human body.

Correct Answer: Sclera
The sclera is the white part of the human eye: the tough outer coat that protects the eyeball and holds its shape, with the transparent cornea at the front.
Correct Answer: Veins
Veins carry blood back to the heart: unlike arteries, which carry blood away from the heart, veins return it, usually deoxygenated, with valves that stop backflow.
Correct Answer: Deoxygenated Blood
Blood without oxygen is called deoxygenated blood: it has given up its oxygen to the tissues and returns through the veins to the heart and lungs, appearing dark red.
Correct Answer: Pancreas
The pancreas secretes digestive enzymes and hormones: its exocrine tissue releases digestive enzymes into the gut, while its islets of Langerhans release hormones, including insulin, into the blood — a dual exocrine and endocrine organ.

Correct Answer: Photometer
A photometer measures light intensity: it measures how much light falls on a surface or is emitted by a source, in units such as lux.
Correct Answer: Fathometer
A fathometer measures the depth of oceans: it times sound echoes sent down to the seabed, the same echo-sounding principle as a modern echo sounder.
Topic Section
2 solved MCQs shown directly below
Correct Answer: East
The sun rises in the east: because the Earth rotates eastward, the sun appears in the east in the morning and sets in the west.
Correct Answer: Nitrogen
Nitrogen is the most abundant gas in Earth's atmosphere: about 78% of dry air is nitrogen, followed by about 21% oxygen and about 1% argon.
Topic Section
3 solved MCQs shown directly below
Correct Answer: Uranus
Uranus rotates on its side: its axis is tilted about 98° to its orbit, probably after a giant ancient collision, so it rolls around the Sun almost on its side.
Correct Answer: Mercury
Mercury has the shortest year: closest to the Sun, it completes one orbit in only about 88 Earth days.
Correct Answer: Neil Armstrong
Neil Armstrong was the first man to set foot on the Moon: commander of Apollo 11, he stepped onto the lunar surface on 20 July 1969, followed by Buzz Aldrin.

4 solved MCQs shown directly below
Correct Answer: Digestion
Digestion is the process of breaking food into simpler substances: mechanical and chemical breakdown in the gut turns food into molecules small enough to be absorbed into the blood.
Correct Answer: Hummingbird
The hummingbird is the smallest bird in the world: the bee hummingbird of Cuba, about 5-6 cm long and under 2 grams, is the smallest of all.
Correct Answer: Elephant
The elephant is the largest land animal: the African savanna elephant, up to about 3-4 metres tall and 6 tonnes, is the largest land animal alive today.
Correct Answer: Sailfish
The sailfish is the fastest aquatic animal: it can burst to about 110 km/h, using its sail-like dorsal fin and long bill when hunting.

Questions
No. This is a practice set built from the Sir Adnan '1000 Advanced Booklet Everyday Science' one-liner compilation. It is labelled practice in the title, slug and paperType and must not be quoted as an official past paper.
This stretch of the booklet largely restates its own earlier parts: 17 of the 50 items repeat facts already published in Q1–750 of the same booklet (aorta, seismology, the 72 pulse, the pituitary master gland, pancreatic insulin, oxygen in respiration, femur, graphite pencils, penicillin, carbon dioxide from burning fuel, the medulla, the ovum, vitamin D and rickets, the 22 skull bones, vitamin K and clotting, chalk as calcium carbonate, and red blood cells carrying oxygen). Those facts are cross-linked to their earlier publication, not re-extracted.
The booklet prints a statement and its answer only, with no options. Each item is published in the standard 4-option MCQ format with 3 authored plausible distractors, under the 2026-10-28 single-format decision; the answers themselves are the booklet's verified standard answers.
Not strictly: caesium also melts just above room temperature (about 28.5°C, against gallium's 29.8°C). Mercury is the only metal liquid at ordinary room temperature, and gallium is the booklet's conventional second answer.
