The question asks to identify the author of the book “Mein Kampf.” “Mein Kampf,” which translates to “My Struggle,” is an autobiographical manifesto that outlines the author's political ideology and future plans for Germany.

The correct answer is Adolf Hitler. Hitler wrote this book while imprisoned after the failed Beer Hall Putsch in 1923. It became a foundational text for Nazism, detailing his antisemitic views, racial theories, and expansionist foreign policy, which profoundly influenced the course of World War II and the Holocaust.

• Bill Clinton served as the 42nd President of the United States and is known for his political memoirs, not “Mein Kampf.”
• Nelson Mandela was an anti-apartheid revolutionary and former President of South Africa, famous for his autobiography “Long Walk to Freedom.”
• All of these is incorrect because only one individual authored “Mein Kampf.”

Thus, Adolf Hitler is the sole author of “Mein Kampf.”

The question asks to identify the founder of Facebook. Facebook is a globally recognized social networking service that revolutionized online communication.

The correct answer is Mark Zuckerberg. Mark Zuckerberg co-founded Facebook (originally 'Thefacebook') in 2004 while he was a student at Harvard University, along with fellow students Eduardo Saverin, Andrew McCollum, Dustin Moskovitz, and Chris Hughes. He has been the chairman and CEO of Meta Platforms (Facebook's parent company) since its inception.

• Michael S. Dell is the founder of Dell Technologies, a prominent computer technology company.
• Bill Gates is the co-founder of Microsoft, a multinational technology corporation known for its software and operating systems.
• Tim Berners-Lee is credited with inventing the World Wide Web, a foundational technology for the internet.

Therefore, Mark Zuckerberg is accurately identified as the founder of Facebook.

The groundbreaking collection of poetry titled “Mavra” was written by Noon Meem Rashid. Published in 1940, 'Mavra' is considered a landmark work in modern Urdu literature. Rashid is celebrated for pioneering free verse in Urdu poetry, breaking away from traditional forms and meters, and introducing new themes and expressions. His work significantly influenced subsequent generations of Urdu poets.

• Ismat Chughtai was a renowned Urdu short story writer and novelist, known for her progressive and often controversial themes, but not the author of 'Mavra'.
• Krishan Chandar was a prominent Urdu short story writer and novelist, known for his realistic and satirical works, but not associated with 'Mavra'.
• Mumtaz Mufti was an acclaimed Urdu short story writer and novelist, known for his unique style and psychological insights, but not the author of 'Mavra'.

Windows 10 is a prime example of an operating system (OS). An operating system is fundamental system software that manages computer hardware and software resources. It provides common services for computer programs and acts as an intermediary between the user and the computer's hardware, allowing other software to run and users to interact with the machine.

• Type of computer is incorrect; Windows 10 is software, not a physical computer.
• Utility software performs specific tasks to maintain the computer (e.g., antivirus, disk defragmenter), but an OS is the core system that enables all other software.
• Application software (e.g., web browsers, word processors) runs *on* an operating system to perform user-specific tasks, whereas the OS itself is the foundational layer.

The Liaquat-Nehru Pact, also known as the Delhi Pact, was a significant bilateral agreement signed between India and Pakistan in 1950. This pact was signed on April 8, 1950, by the then Prime Ministers of India, Jawaharlal Nehru, and Pakistan, Liaquat Ali Khan. Its primary objective was to ensure the protection and rights of minorities in both countries, particularly in the aftermath of the communal violence that followed the Partition of India in 1947.

• The years 1964, 1965, and 1966 are incorrect. These years fall much later than the actual signing of the pact, which was a foundational agreement in the early years of both nations.

SPSS is a widely recognized and utilized software package for statistical analysis. Its full form is Statistical Package for Social Sciences. Developed by IBM, it is extensively used across various fields, particularly in academic research, market research, and health sciences, for data management, advanced analytics, and reporting. The software provides a user-friendly interface for performing complex statistical procedures.

• Statistical Package for Social Studies is incorrect; 'Studies' is not the precise term in the official acronym.
• Statistical Package for Sampling Studies is also incorrect; while sampling is part of statistics, it doesn't represent the full scope of SPSS's capabilities or its official name.
• Statistical Package for Social Service is inaccurate; 'Service' is not part of the correct expansion.

The Earth's atmosphere contains various gases that absorb different wavelengths of solar radiation. Water vapor is the most significant natural greenhouse gas and a primary absorber of infrared (IR) radiation emitted by the sun and re-radiated from Earth's surface. Its molecular structure allows it to efficiently absorb and re-emit IR energy, playing a crucial role in the planet's heat budget and the greenhouse effect.

• Violet is a color in the visible light spectrum, not a gas that absorbs infrared radiation.
• Carbon dioxide is indeed a major greenhouse gas and absorbs infrared, but water vapor generally accounts for a larger share of atmospheric IR absorption.
• Ozone primarily absorbs harmful ultraviolet (UV) radiation in the stratosphere, protecting life on Earth, rather than being the main absorber of solar infrared.

A syllabus is a crucial document that provides a comprehensive outline of a specific academic course. It details the topics to be covered, learning objectives, required readings, assignments, grading criteria, and important policies. It serves as a contract between the instructor and students, setting expectations for the course.

• Outline is too general; while a syllabus contains an outline, the term itself doesn't specifically refer to a course document.
• Curriculum is a broader term, encompassing the entire set of courses and educational content offered by a school or program, not just a single course.
• Student refers to an individual enrolled in a course and is irrelevant to the subject matter of the question.

Therefore, 'Syllabus' is the most accurate term for an outline of subjects covered in a specific course.

The question asks about assessment carried out throughout a course. Formative assessment is the correct answer. This type of assessment is designed to monitor student learning during instruction, providing ongoing feedback that can be used by instructors to improve their teaching and by students to improve their learning. It is 'for learning,' helping to 'form' understanding.

• Examples include quizzes, homework, class discussions, and drafts of assignments.
• Diagnostic assessment is conducted *before* instruction to assess prior knowledge and identify learning gaps.
• Initial assessment is synonymous with diagnostic, referring to assessment at the beginning.
• Summative assessment is conducted *at the end* of a course or unit to evaluate overall learning against a standard, such as final exams or major projects.

The idiom 'Fly in the face of' means to openly disregard, defy, or go against something, often a rule, convention, or established fact. It implies a direct confrontation or opposition to something. Therefore, 'Against' is the most accurate meaning.

• For example, if someone's actions 'fly in the face of' company policy, it means their actions are directly contrary to or defy that policy.
• While 'Disobey' is related, 'Against' captures a broader sense of contradiction or defiance, not just a direct command. One can fly in the face of logic or evidence, which isn't strictly 'disobeying' but rather acting contrary to.
• 'Reward' and 'Joyful' are completely unrelated to the meaning of the idiom, representing opposite or irrelevant concepts.

The original sentence, 'Lying on the grass, a snake bit him,' contains a dangling modifier. The introductory phrase 'Lying on the grass' incorrectly suggests that the snake was lying on the grass, not the person. The phrase must logically modify the subject immediately following it.

• The correct sentence is 'Lying on the grass, he was bitten by a snake.' Here, 'Lying on the grass' correctly modifies 'he,' clarifying that the person was the one on the grass.
• Option A, 'Lying on the grass, a snake was bitten by him,' still implies the snake was on the grass.
• Option B, 'A snake bit him lying on the grass,' is grammatically correct but changes the sentence structure significantly and doesn't directly address the dangling modifier in the initial position as effectively as option C.
• Therefore, option C provides the most accurate and grammatically sound correction.

The question asks to identify Usher and Zakat. The correct answer is Two kinds of tax in Islam. These terms refer to specific forms of obligatory financial contributions within Islamic economic jurisprudence, designed for wealth redistribution and social welfare.

• Zakat is an annual obligatory charity or religious tax paid by Muslims who meet a certain threshold of wealth (nisab) to specific categories of beneficiaries, such as the poor and needy. It is one of the Five Pillars of Islam.
• Usher (or Ushr) is an agricultural tax levied on the produce of land, typically 10% for naturally irrigated land and 5% for artificially irrigated land. Both are fundamental components of the Islamic economic system.
• Options like 'Two prominent warriors' or 'Two months of Islamic calendar' are incorrect as they bear no relation to the established meanings of Usher and Zakat.

The question asks about the gas commonly used in welding. Acetylene (C2H2) is the correct answer because it is a highly combustible hydrocarbon gas that, when combined with oxygen in an oxy-fuel torch, produces an extremely hot flame (up to 3,500 °C or 6,330 °F). This intense heat is ideal for melting and joining metals, making it a primary fuel gas for various welding and cutting applications.

• Hydrogen can be used in some specialized welding processes, but it does not achieve the same high temperatures as oxy-acetylene and is not as universally applied for general welding.
• Nitrogen is an inert gas primarily used as a shielding gas in certain welding techniques to prevent atmospheric contamination, not as a fuel gas to generate heat.
• Therefore, 'all' is incorrect as hydrogen and nitrogen do not serve the same primary fuel purpose as acetylene in common welding practices.

Keyboard navigation keys are essential tools for efficient text editing and document manipulation. Understanding the primary function of each key can significantly improve productivity when working with various applications.

• D: Moves cursor to beginning of line is the correct primary function of the Home key. When pressed alone, it repositions the cursor to the leftmost character of the current line of text.
• A: Moves cursor to beginning of document is incorrect for the standalone Home key; this action typically requires a combination like Ctrl+Home.
• B: Moves cursor to beginning of paragraph is not the standard function of the Home key.
• C: Moves cursor to beginning of screen is also not its primary function; it's line-specific, not screen-specific.

The theory of evolution is a cornerstone of modern biology, explaining the diversity of life on Earth through natural processes over vast periods. Its development revolutionized scientific understanding of life's origins and development.

• C: Darwin, specifically Charles Darwin, is credited with developing the theory of evolution by natural selection. His seminal work, 'On the Origin of Species,' published in 1859, presented compelling evidence and a mechanism for evolutionary change.
• A: Maulana Hasan Ahmad Madani and B: Shabir Ahmad Usmani were prominent Islamic scholars, not figures in evolutionary biology.
• D: Mendeleev, Dmitri Mendeleev, is renowned for formulating the Periodic Law and creating the periodic table of elements in chemistry, not for the theory of evolution.

Treaties are formal agreements between states that often conclude wars and establish new international orders. The mid-17th century saw a pivotal treaty that reshaped European politics and laid foundations for modern international relations.

• A: Treaty of Westphalia, signed in 1648, is the correct answer. It comprised a series of peace treaties that ended both the Thirty Years' War in the Holy Roman Empire (involving German states and others) and the Eighty Years' War between Spain and the Dutch Republic, establishing the concept of state sovereignty.
• B: Treaty of Paris refers to several treaties throughout history, none specifically ending this particular conflict involving Spain, Germany, and the Dutch.
• C: Treaty of Versailles was signed in 1919, ending World War I, centuries after the conflicts mentioned.
• D: None is incorrect because the Treaty of Westphalia directly addresses the question.

The age at which a president assumes office is a notable historical detail. While Theodore Roosevelt was younger when he *succeeded* to the presidency, the question specifically asks for the youngest *elected* president, referring to the age at inauguration after winning an election.

• D: John F. Kennedy holds the distinction of being the youngest person ever *elected* to the U.S. presidency. He was inaugurated on January 20, 1961, at the age of 43.
• A: James Monroe was 58 when he became president.
• B: Abraham Lincoln was 52 when he took office.
• C: Herbert Hoover was 54 at his inauguration. These individuals were all significantly older than Kennedy when they assumed the presidency after being elected.

The Earth's ozone layer, located in the stratosphere, is crucial for absorbing harmful ultraviolet (UV) radiation from the sun. Certain human-made chemicals can deplete this protective layer, leading to increased UV exposure and associated health risks.

• A: CFCs (Chlorofluorocarbons) are the primary ozone-depleting substances. These chemicals, once widely used in refrigerants and aerosols, release chlorine atoms that catalytically destroy ozone molecules.
• B: Carbon dioxide is a major greenhouse gas contributing to climate change, but it is not a primary ozone-depleting substance.
• C: Carbon monoxide is a toxic air pollutant, but it does not directly deplete the ozone layer.
• D: Acetylene is a hydrocarbon gas used in welding, and it is not known to be an ozone-depleting substance.

The CPU, or Central Processing Unit, is often referred to as the 'brain' of a computer. It is responsible for executing instructions, performing calculations, and managing the overall flow of data within the system. Understanding its full form is fundamental to computer literacy.

• A: Central Processing Unit is the correct and universally accepted full form of CPU. It accurately describes its central role in processing information.
• B: Computer Process is too vague and not the correct acronym. While the CPU is involved in computer processes, this is not its name.
• C: Computer Protection Unit is incorrect. The CPU's primary function is processing, not protection, which is typically handled by security software or hardware.
• D: None is incorrect because option A is accurate.

An antonym is a word that has the opposite meaning of another word. Understanding antonyms helps in expanding vocabulary and comprehending nuances in language.

• The correct answer is A: Active. The word "dormant" means inactive, in a state of temporary inactivity, or not currently growing or developing. For example, a dormant volcano is not erupting, and dormant seeds are not germinating. Therefore, the direct opposite of being inactive or suspended is being Active, meaning engaged in action, moving, or functioning.
• B: Transient means lasting only for a short time; impermanent. This is not the opposite of dormant, as something dormant can be either transient or prolonged.
• C: Permanent means lasting or intended to last indefinitely. This describes duration, not the state of activity, and is not the antonym of dormant.
• D: all is incorrect because only "Active" serves as the direct antonym for "dormant."

Goitre is a medical condition characterized by an abnormal enlargement of the thyroid gland, which is located in the neck. The thyroid gland plays a crucial role in producing hormones essential for metabolism, growth, and development.

• The correct answer is B: Iodine. Deficiency of iodine is the most common cause of goitre worldwide. The thyroid gland requires iodine to synthesize thyroid hormones (thyroxine and triiodothyronine). When iodine intake is insufficient, the thyroid gland attempts to compensate by growing larger to capture more available iodine, leading to the characteristic swelling known as goitre.
• A: Potassium is an essential electrolyte, but its deficiency does not directly cause goitre.
• C: Protein deficiency can lead to various nutritional problems, but it is not the primary cause of goitre.
• D: all is incorrect because only iodine deficiency is the direct and primary cause among the given options.

The invention of plastic marked a revolutionary advancement in materials science, leading to the development of countless modern products. The first fully synthetic plastic was a significant breakthrough.

• The correct answer is B: Leo Baekeland. In 1907, Leo Baekeland, a Belgian-American chemist, invented Bakelite. This was the world's first fully synthetic plastic, meaning it was entirely man-made and not derived from natural polymers. Bakelite was durable, heat-resistant, and electrically non-conductive, quickly finding widespread applications in electrical insulation, car parts, and various consumer goods, thus pioneering the plastics industry.
• A: Louis Pasteur was a French chemist and microbiologist famous for pasteurization and germ theory, not plastic.
• C: Robert Bunsen was a German chemist known for the Bunsen burner and his work in spectroscopy.
• D: Amedee Avogadro was an Italian scientist known for Avogadro's number and his contributions to molecular theory.

This question asks to identify the author of the renowned Urdu novel "نادار لوگ" (Nadar Log), which translates to "Destitute People." The novel is celebrated for its profound social commentary and realistic portrayal of human struggles.

• The correct answer is C: عبد الله حسین (Abdullah Hussain). Abdullah Hussain was a highly acclaimed Pakistani Urdu novelist and short story writer. "نادار لوگ" is one of his significant works, known for its exploration of themes like poverty, social injustice, and the human condition, reflecting his distinctive literary style.
• A: علیم اختر (Aleem Akhtar) is not recognized as the author of this particular novel.
• B: پر نام چند (Premchand) was a legendary Indian writer, primarily known for his Hindi and Urdu short stories and novels, but he did not write "نادار لوگ."
• D: اپنی خیر احمد (Ahmad Nadeem Qasmi) was a prominent Pakistani Urdu poet, short story writer, and journalist, but he is not the author of "نادار لوگ."

The ear is a complex sensory organ responsible for both hearing and balance, divided into outer, middle, and inner sections. Hearing involves the conversion of sound waves into electrical signals that the brain can interpret.

• The correct answer is A: Cochlea. The cochlea is a spiral-shaped, fluid-filled structure in the inner ear containing the Organ of Corti. This organ houses thousands of tiny hair cells that convert mechanical vibrations into electrical nerve impulses, which are then transmitted to the brain for sound perception.
• B: Ossicle refers to the three small bones (malleus, incus, stapes) in the middle ear that amplify and transmit vibrations, but they don't perform the actual hearing transduction.
• C: Pinna is the visible outer part of the ear that collects and funnels sound waves into the ear canal.
• D: Eardrum (tympanic membrane) vibrates in response to sound waves, initiating the transmission process to the ossicles, but it does not convert vibrations into neural signals.
