The Movement for the Restoration of Democracy (MRD) was a significant political alliance formed in Pakistan in 1981. Its primary objective was to oppose the military government and dictatorship of General Zia-ul-Haq, advocating for the restoration of democratic rule and the 1973 Constitution. Therefore, option A is the correct answer.

• Yahya Khan (B) was a military ruler before Zia-ul-Haq, but the MRD specifically targeted Zia's regime.
• Ayub Khan (C) was another military dictator, but his rule preceded the formation of the MRD.
• Pervaiz Musharraf (D) came to power much later, and the MRD had largely dissolved by then, though similar movements emerged against his rule.

Summative assessment aims to evaluate student learning at the end of an instructional unit, course, or academic year. Its primary purpose is to summarize what students have learned and to assign grades or certify competence. Therefore, option B, 'End of course,' accurately describes its main objective.

• Instruction before class (A) is not an aim of summative assessment; this might relate to pre-assessment or diagnostic activities.
• Find problem (C) is typically a goal of diagnostic assessment, which identifies learning difficulties.
• Check student weakness (D) is more aligned with formative assessment, which provides ongoing feedback to improve learning during instruction, rather than summarizing it at the end.

Energy is the fundamental capacity to do work, which is defined as the transfer of energy that occurs when a force is applied over a distance. This foundational concept in physics explains that any action requiring effort or causing a change in state involves energy. Therefore, option A is precisely accurate.

• Force (B) is a push or pull that can cause an object to accelerate, but it is not the capacity to do work itself; it is what performs the work.
• Motion (C) is the act of changing position or location, which is often a result of work being done, rather than the capacity to do it.
• Momentum (D) is a measure of the mass and velocity of an object, indicating its quantity of motion, but it does not represent the inherent capacity to perform work.

The word "callous" describes someone who is insensitive, unfeeling, or shows a cruel disregard for others' feelings. Therefore, its direct antonym would be a word that expresses the opposite quality: compassion, empathy, or benevolence. "Kind" perfectly fits this description, meaning friendly, generous, and considerate.

• While "sensitive" implies awareness of feelings, "kind" more directly contrasts the lack of compassion in "callous."
• "Tender" can mean delicate or gentle, but "kind" is a stronger antonym for the emotional disposition.
• "Careless" is unrelated to the meaning of callous, referring to a lack of attention or concern for consequences, not feelings.

Understanding antonyms enhances vocabulary and comprehension.

According to the official rules of World Athletics, the standard width for the javelin runway is 4 meters. This specific dimension is crucial for ensuring fair competition and athlete safety in the javelin throw event. The runway provides the athlete with a defined area to build momentum before releasing the javelin, and its precise width is part of the standardized regulations that govern track and field sports globally.

• Options such as 2 meters, 1.5 meters, and 2.5 meters are incorrect widths according to international athletic standards.

Adhering to these specifications is vital for the integrity and consistency of athletic competitions.

The conquest of Orpris, commonly known as Cyprus, by Muslim forces occurred in the 28th Hijri year (28 H). This significant historical event took place during the caliphate of Uthman ibn Affan, specifically around 649 CE. The island of Cyprus was strategically important in the Mediterranean, and its conquest marked an expansion of early Islamic influence and naval power.

• The other options, 30 H, 32 H, and 29 H, are incorrect dates for this specific historical conquest.

Accurate knowledge of key historical dates and events is essential for understanding the timeline of early Islamic history and its geographical expansion.

A severe deficiency of Vitamin D primarily results in Rickets in children. Rickets is a condition characterized by soft, weak bones, bone pain, and impaired growth, caused by the body's inability to properly absorb calcium and phosphate, which Vitamin D facilitates.

• Scurvy is caused by a deficiency of Vitamin C.
• Night blindness is typically associated with Vitamin A deficiency.
• While Osteoporosis involves bone density loss, it is primarily an adult condition, and severe Vitamin D deficiency in adults leads to osteomalacia, which is distinct from childhood rickets.

Understanding the specific health consequences of vitamin deficiencies is crucial for health and nutrition knowledge.

The literal meaning of philosophy is derived from ancient Greek words: "philos," meaning love, and "sophia," meaning wisdom. Thus, philosophy literally translates to "love of wisdom." This foundational understanding reflects the discipline's core pursuit: a deep and rational inquiry into fundamental questions about existence, knowledge, values, reason, mind, and language.

• While "love of truth," "love of history," and "love of values" are related to philosophical inquiry, they do not capture the precise etymological origin and comprehensive scope implied by "love of wisdom."

The term emphasizes the pursuit and appreciation of profound understanding.

The sentence "I know why people are making noise" is a complex sentence. A complex sentence is characterized by having one independent clause and at least one dependent clause. In this sentence, "I know" is the independent clause, which can stand alone as a complete thought. The phrase "why people are making noise" is a dependent noun clause that functions as the direct object of the verb "know." It cannot stand alone as a complete sentence.

• A simple sentence has only one independent clause.
• A compound sentence has two or more independent clauses.
• A compound-complex sentence has two or more independent clauses and at least one dependent clause.

Understanding clause structure is crucial for identifying sentence types.

To find the total amount, we need to understand that Rs. 7885 represents 10% of the whole. If 10% of the total amount is Rs. 7885, then to find 100% (the total amount), we can multiply Rs. 7885 by 10. The calculation is straightforward: 7885 × 10 = 78850. Therefore, the total amount is Rs. 78850.

• Options like Rs 70050, Rs 59850, and Rs 55850 are incorrect calculations, likely resulting from misinterpreting the percentage or performing incorrect arithmetic operations.

This problem tests basic percentage calculation skills, which are fundamental in everyday financial literacy.

An isthmus is precisely defined as a narrow strip of land that connects two larger landmasses while separating two bodies of water. A classic example is the Isthmus of Panama, connecting North and South America and separating the Atlantic and Pacific Oceans.

• A strait is the opposite: a narrow passage of water connecting two larger bodies of water.
• A bay is a broad inlet of the sea where the land curves inward.
• A weir is a low dam built across a river to alter its flow.

Therefore, "Isthmus" is the only term that accurately describes the geographical feature mentioned, highlighting a key concept in physical geography.

The Makli Hill Graveyard, also known as the Makli Necropolis, is correctly located near the city of Thatta in the Pakistani province of Sindh. This vast funerary site is one of the largest in the world, spanning approximately 10 square kilometers and housing hundreds of thousands of tombs and graves. It is a UNESCO World Heritage Site, renowned for its intricate architecture and historical significance, dating from the 14th to the 18th centuries.

• Hyderabad, Taxila, and Karachi are significant cities in Pakistan, but none of them are the location of the Makli Hill Graveyard.

"Video Graphics Array" is the correct expansion for VGA.

VGA is a foundational standard for computer display hardware, initially introduced by IBM in 1987. It defines the specifications for the display adapter, monitor, and the signals used to transmit video information. This standard was crucial in the early development of personal computing graphics, providing a common interface for displaying images and text on monitors. Even today, the term VGA is often used to refer to the D-sub 15-pin connector found on many graphics cards and monitors. The other options,

• "Visual Graphics Adapter,"
• "Virtual Graphics Adapter," and
• "Volatile Graphics Adapter,"

are incorrect acronyms and do not represent any recognized computer display standard. Understanding such acronyms is fundamental in computer literacy and hardware knowledge.

The question asks for a word describing a "thing liable to break easily." The most precise answer is Brittle. Brittle describes a material that is hard but breaks or shatters easily when subjected to stress, without significant plastic deformation. This foundational concept relates to material science and properties. Distractor Breakable is a general term meaning capable of being broken, but "brittle" specifically refers to the material's inherent property of shattering. Ductile is the opposite of brittle; it describes a material that can be drawn out into a thin wire without losing toughness, meaning it deforms before breaking. Fragile is similar to breakable, implying delicacy and ease of damage, but "brittle" more accurately captures the material's characteristic of shattering rather than bending or deforming.

The question requires the correct phrasal verb to complete the sentence "The police are -----the incident." The correct answer is Looking into. The phrasal verb "look into" means to investigate, examine, or inquire about something, which is precisely what police do when dealing with an incident. This foundational concept is about understanding idiomatic English expressions. Distractor Looking on means to observe an event without participating, which is not the role of the police in an incident. Looking for means to search for something or someone, implying a missing item or person, not an investigation of an event. Looking at means to observe or consider, but "looking into" implies a more thorough and active investigation, making it the most appropriate choice for police action regarding an incident.

The question asks about the primary form of energy produced directly in nuclear fission. The correct answer is Thermal energy. Nuclear fission is a process where the nucleus of an atom splits into two or more smaller nuclei, releasing a tremendous amount of energy, predominantly in the form of heat. This foundational concept is central to how nuclear power plants operate, where this thermal energy is used to heat water, produce steam, and drive turbines to generate electricity. Distractor Electrical energy is the end product after conversion from thermal energy, not the direct output of fission. Chemical energy is associated with chemical reactions, not nuclear processes. Gas is not a form of energy produced by fission. Thus, thermal energy is the direct and primary output.

The question asks for the full designation of a US theatre-level unified combatant command of the Department of Defense. The correct answer is USCENTCOM, which stands for United States Central Command. This foundational concept relates to the organizational structure of the US military, where unified combatant commands are established to provide command and control of military forces for specific geographic regions or functional areas. USCENTCOM is responsible for US security interests in 21 nations, including the Middle East, Central Asia, and parts of South Asia. Distractor CENTCOM is merely an abbreviation and not the full, official designation as requested. Therefore, "Both" is incorrect because CENTCOM is not the complete name. "None" is incorrect as USCENTCOM is a valid and correct option.
