Brian Lara famously broke Hanif Muhammad's long-standing record in first-class cricket. On June 6, 1994, playing for Warwickshire against Durham, Lara scored an astonishing unbeaten 501 runs, surpassing Hanif Muhammad's 499 set in 1959. This monumental innings remains the highest individual score in first-class history, a testament to Lara's exceptional skill and endurance, achieved just weeks after his world record Test score of 375. A.B. de Villiers, Sachin Tendulkar, and Ricky Ponting are all legendary batsmen with numerous international and domestic records, but none are associated with breaking this specific first-class highest score. Lara's achievement solidified his status as one of cricket's greatest batsmen, demonstrating an unparalleled ability to compile massive scores and etch his name into cricketing folklore.

The correct answer is 35. This question follows a simple numerical pattern in which each number is multiplied by one less than itself. For example, 5 = 5 × (5 − 2) = 5 × 3 = 15 and 6 = 6 × (6 − 2) = 6 × 4 = 24. Applying the same rule to 7 gives 7 × (7 − 2) = 7 × 5 = 35. Therefore, the missing value is 35. Such pattern-recognition questions are commonly asked in intelligence and aptitude tests to assess logical reasoning rather than mathematical formulas.
When solving number series or analogy questions, it is important to identify the relationship between the given numbers before attempting the next value. In this case, the multiplier increases by one as the original number increases: 5 × 3 = 15, 6 × 4 = 24, and 7 × 5 = 35. Recognizing this consistent rule leads directly to the correct answer without requiring complex calculations. Pattern-based reasoning is widely tested in competitive examinations because it measures analytical thinking and problem-solving ability.
Why the other options are incorrect:
30 is incorrect because it does not follow the multiplication pattern established by the previous values.
40 is incorrect because no valid mathematical relationship from the given examples produces this result.
45 is incorrect because it does not satisfy the consistent rule of multiplying the number by (number − 2).

Miqat is the designated boundary where Hajj pilgrims must enter the state of Ihram, signifying their intention for pilgrimage. Mina, Makkah, and Madina are significant locations in Hajj but not the specific point for assuming Ihram.
The correct answer is Rabies because hydrophobia, which literally translates to the fear of water, is a hallmark clinical sign that develops during the advanced stages of a furious rabies infection.
Step 1 (Pathology of Hydrophobia): The rabies virus is a neurotropic pathogen that targets the host's central nervous system . As the infection progresses to the brainstem, it severely affects the cranial nerves responsible for controlling the synchronization of respiration and swallowing .
Step 2 (The Hydrophobic Spasm): When an infected person attempts to drink or even hears liquids, it triggers violent, excruciatingly painful involuntary spasms of the diaphragm and laryngeal throat muscles . This severe physical distress creates a profound psychological dread and systematic avoidance of water .
Incorrect Options:
Malaria is incorrect because it is a mosquito-borne parasitic disease characterized by cyclic high fevers, chills, shaking, and anemia rather than neuromuscular swallowing failures.
Cholera is incorrect because it is an acute bacterial intestinal infection caused by consuming contaminated food or water, resulting in severe watery diarrhea and rapid dehydration.
AIDS is incorrect because Acquired Immunodeficiency Syndrome is a chronic, life-threatening condition caused by HIV that breaks down the immune system, opening the body to opportunistic infections.
LAN is an acronym for Local Area Network, which connects computers within a limited geographical area, typically a home or office. The other options are incorrect expansions of the acronym.
The correct answer is Salt because sodium chloride (NaCl) is the precise chemical name for common table salt used daily in cooking and food preservation.
Step 1 (Chemical Composition): Sodium chloride is an ionic compound made up of equal parts of the elements sodium (Na) and chlorine (Cl). It crystallizes into cubic structures and is essential for biological life, regulating fluid balances and nerve impulses.
Incorrect Options:
Baking soda is incorrect because baking soda is the common name for an entirely different chemical compound, sodium bicarbonate (NaHCO3).
Sugar is incorrect because sugar is a carbohydrate organic compound, typically sucrose (C12H22O11), derived from plant sources.
None of these is incorrect because salt is the exact household name for this mineral.
The correct answer is Vitamin D because human skin naturally synthesizes this crucial nutrient when exposed to ultraviolet B (UVB) radiation from the sun.
Step 1 (Biological Synthesis): When solar UVB rays strike the skin, they interact with a pre-existing compound called 7-dehydrocholesterol. This interaction triggers a chemical conversion that turns the compound into Vitamin D3 (cholecalciferol), which the liver and kidneys later activate.
Incorrect Options:
Vitamin A is incorrect because it is a fat-soluble vitamin obtained directly through dietary sources like animal liver or plant-based carotenoids, not through solar radiation.
Vitamin C is incorrect because it is a water-soluble antioxidant that humans must ingest through foods like citrus fruits, as our bodies cannot synthesize it.
Vitamin E is incorrect because it represents a group of fat-soluble compounds found in nuts, seeds, and vegetable oils that function as cellular antioxidants.
The correct answer is Newton because Sir Isaac Newton formally published the mathematical laws governing gravity in his groundbreaking 1687 work, Philosophiae Naturalis Principia Mathematica.
Step 1 (The Scientific Principle): Newton's Law of Universal Gravitation states that every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Incorrect Options:
Dalton is incorrect because John Dalton is famous for pioneering modern atomic theory and researching color blindness, not gravitation.
Einstein is incorrect because Albert Einstein developed the Theory of General Relativity, which describes gravity as the curvature of spacetime rather than postulating the initial universal law.
None of these is incorrect because Newton is the exact historical scientist responsible for this law.
C.Altering human beings by changing their genetic components
D.Water sports
Correct answer is:
C. Altering human beings by changing their genetic components
The correct answer is Altering human beings by changing their genetic components because eugenics is historically defined as a movement and study aimed at modifying the genetic composition of human populations.
Step 1 (Etymology and Concept): Coined in the 19th century, the term eugenics stems from Greek roots meaning 'good creation' or 'well-born'. It represents theories and practices that attempted to influence human hereditary traits by selectively encouraging or discouraging specific reproductive outcomes.
Incorrect Options:
Water diseases is incorrect because the study of waterborne pathogens and related public health infections falls under epidemiology and microbiology.
Study of flowers is incorrect because the scientific study of plants, including flowers, is called botany or floriculture.
Water sports is incorrect because water sports represent recreational or competitive physical activities performed in or on water, completely unrelated to genetic sciences.
The correct answer is Directories. In a computer system, directories (commonly called folders) organize files in a hierarchical structure, functioning just like physical folders that organize paper documents in a filing cabinet. They provide a logical way to store, group, and retrieve files.
Documents: These are the actual files themselves, not the containers that organize them.
Filing: This refers to the action or process, not the system structure.
Recycle bin: This is a temporary storage location for deleted items, not a primary organizational tool.
Therefore, the term that correctly describes the organizational system is "Directories".
China holds the distinction of being the country with the largest internet user base globally. This is primarily attributable to its immense population, which provides a vast pool of potential users, coupled with aggressive government and private sector initiatives promoting digital adoption and infrastructure development. While countries like India are rapidly expanding their internet access and user numbers, they currently remain second to China. The USA, despite having high internet penetration, has a significantly smaller overall population, leading to a lower total number of internet users compared to China. Russia also has a considerably smaller internet-using population. Therefore, China's unique combination of population size and digital growth firmly establishes its position as the leader in internet usage.
