About this paper
Part 14 (Q651–700) 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 31 of 50 printed items are published. 19 restate facts already published in earlier parts of the same booklet and are cross-linked, not re-extracted: Q651 metal used in electric wires (Q114 in Q101-150); Q652 organ purifying blood by filtration (Q288 in Q251-300); Q653 study of stars (Q633 in Q601-650, published as the branch of science dealing with space); Q659 blood cells helping in clotting (Q214 in Q201-250 / Q283 in Q251-300); Q660 SI unit of energy (Q343 in Q301-350); Q663 source of energy for the Sun (Q577 in Q551-600); Q666 chemical formula of methane (Q28 in Q1-50 / Q304 in Q301-350, published with CH₄ in the answer); Q667 blood cells carrying oxygen (Q281 in Q251-300); Q670 gas known as marsh gas (Q368 in Q351-400); Q676 human heart chambers (Q222 in Q201-250); Q679 metal used in thermometers (Q145 in Q101-150); Q680 human skeleton bones (Q205 in Q201-250); Q681 vitamin necessary for vision (Q233 in Q201-250); Q685 organ producing bile (Q284 in Q251-300); Q686 largest internal organ (Q202 in Q201-250); Q687 normal pH of human blood (Q215 in Q201-250, published as 7.35–7.45, of which 7.4 is the conventional single value); Q694 smallest bone in the human body (Q203 in Q201-250 / Q275 in Q251-300); Q696 energy stored in food (Q374 in Q351-400); Q698 universal recipient blood group (Q218 in Q201-250). One printed answer is corrected to the current standard answer (Q683 most moons: Saturn, not the booklet's Jupiter). No printed item in this stretch is dropped as unanswerable.

2 solved MCQs shown directly below
Correct Answer: Anemometer
An anemometer measures wind speed: its cups or vanes turn in the wind, and the rate of rotation gives the speed.
Correct Answer: Hygrometer
A hygrometer measures humidity: it shows how much water vapour is present in the air, often as relative humidity.
Topic Section
5 solved MCQs shown directly below
Correct Answer: Blue Whale
The blue whale is the heaviest mammal — and the heaviest animal known to have lived — reaching about 150-200 tonnes as an adult.
Correct Answer: Genetics
The study of heredity is called genetics: it studies how traits are passed from parents to offspring through genes.
Correct Answer: Cheetah
The cheetah is the fastest land animal, reaching about 60-70 mph (96-113 km/h) in short bursts.
Correct Answer: Zoology
The branch of biology dealing with animals is zoology: it studies the structure, behaviour, classification and life of animals.
Correct Answer: Entomology
The study of insects is called entomology: it covers insects and related arthropods.
Topic Section
6 solved MCQs shown directly below
Correct Answer: Mars
Mars is called the Red Planet because its surface, rich in iron oxide (rust), appears reddish from Earth.
Correct Answer: Yuri Gagarin
Yuri Gagarin was the first man to orbit the Earth: aboard Vostok 1 on 12 April 1961 he completed one orbit in about 108 minutes.
Correct Answer: Jupiter
Jupiter is the largest planet in the solar system: it is more massive than all the other planets combined.
Correct Answer: 365 days
The Earth revolves around the Sun in 365 days: one complete orbit takes about a year, which is why the calendar year is 365 days (with a leap day every four years).
Correct Answer: Saturn
Saturn has the largest number of moons: 274 confirmed moons as of March 2025, more than Jupiter's 95.
Correct Answer: Venus
Venus has a day longer than its year: it rotates once in about 243 Earth days but orbits the Sun in about 225 Earth days.
Topic Section
4 solved MCQs shown directly below
Correct Answer: Oxygen
Oxygen is essential for respiration: the body uses it to break down glucose and release energy in the cells.
Correct Answer: Lungs
The lungs purify the blood of carbon dioxide: CO₂ diffuses from the blood into the air in the lungs and is breathed out, while oxygen is taken in.
Correct Answer: Penicillin
Penicillin was the first antibiotic discovered: Alexander Fleming noticed its bacteria-killing effect in 1928, and it was developed into a drug in the 1940s.
Correct Answer: Anemia
Deficiency of iron causes anemia (iron-deficiency anemia): without enough iron the body cannot make enough haemoglobin, so the blood carries less oxygen.
Topic Section
2 solved MCQs shown directly below
Correct Answer: Vitamin A
Vitamin A is also called retinol: retinol is the preformed, animal-source form of vitamin A, essential for vision.
Correct Answer: Vitamin D
Vitamin D is essential for calcium absorption: it enables the intestines to absorb calcium from food, which is why its deficiency weakens bones.
Topic Section
4 solved MCQs shown directly below
Correct Answer: West to East
The Earth rotates on its axis from west to east (counterclockwise seen from above the North Pole), which is why the Sun appears to rise in the east.
Correct Answer: Ultraviolet Rays
The ozone layer protects us from ultraviolet rays: stratospheric ozone absorbs most of the Sun's harmful UV-B and UV-C radiation before it reaches the surface.
Correct Answer: 23.5°
The Earth is tilted at 23.5° on its axis: this axial tilt is what causes the seasons as the Earth orbits the Sun.
Correct Answer: Stratosphere
The stratosphere contains the ozone layer: most atmospheric ozone sits about 15-35 km above the surface, in the lower stratosphere.
Topic Section
4 solved MCQs shown directly below
Correct Answer: Pascal
The SI unit of pressure is the pascal: one pascal is one newton of force per square metre.
Correct Answer: 3 × 10⁸ m/s
The speed of light in vacuum is 3 × 10⁸ m/s (exactly 299,792,458 m/s), the fastest speed in the universe.
Correct Answer: 212°F
The boiling point of water in Fahrenheit is 212°F at standard atmospheric pressure, the same point as 100°C.
Correct Answer: Albert Einstein
Albert Einstein is called the father of modern physics for his theories of relativity, which reshaped physics in the twentieth century.
Topic Section
4 solved MCQs shown directly below
Correct Answer: Au
The chemical symbol of gold is Au, from its Latin name aurum, meaning 'glow of sunrise'.
Correct Answer: Helium
Helium is the gas used in balloons: it is lighter than air, so it lifts, and unlike hydrogen it is non-flammable, so it is safe.
Correct Answer: Freon
Freon is the conventional exam answer for the gas used in refrigerators: it is the trade name for the chlorofluorocarbon refrigerants once standard in refrigeration.
Correct Answer: Argon
Argon is the gas used in fluorescent lamps: it fills the tube and, with a little mercury vapour, produces the ultraviolet light that the phosphor coating turns into visible light.
Source & verification
Built by GK360 from verified bank questions — every answer rechecked before publishing. Where the source printed no options, the answer options were prepared by GK360; the questions and correct answers are the verified originals.
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: 19 of the 50 items repeat facts already published in Q1–650 of the same booklet (copper wires, kidney purification, astronomy, platelets and clotting, the joule, solar energy from fusion, methane's formula, red blood cells and oxygen, marsh gas, heart chambers, mercury thermometers, 206 bones, vitamin A and vision, bile, largest internal organ, blood pH, the stapes, chemical energy in food, and the AB Positive universal recipient). 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, except Q683, where the booklet's Jupiter is corrected to Saturn.
Saturn does now: 274 confirmed moons as of March 2025, against Jupiter's 95. Jupiter was the long-standing exam answer, which is why the booklet prints it; the item is published with the corrected standard answer and the correction is flagged on it.
