SSC CGL Tier 1 2017 General Awareness Questions with Solutions

Explanation

Cancer is classified as a non-communicable disease because it is not caused by infectious agents that can be transmitted from one person to another. It occurs when abnormal cells in the body begin to divide uncontrollably and spread into surrounding tissues. This process is generally triggered by genetic mutations, environmental factors, or lifestyle choices such as tobacco use, radiation exposure, and poor diet, rather than through the spread of pathogens. Because the underlying causes are physiological and genetic rather than infectious, the disease cannot be caught or spread through social contact, air, or water.

Explanation

An electric motor is an electromechanical device that operates on the principle of electromagnetism. When an electric current flows through a wire coil placed within a magnetic field, it experiences a physical force known as the Lorentz force. This force generates torque on the rotor, causing it to spin. Through this process, the device consumes electrical energy from a power source and transforms it into rotational motion or mechanical work to perform various physical tasks.

Explanation

Optical fibre functions based on the principle of total internal reflection. An optical fibre consists of a central core made of high-quality glass or plastic, which is surrounded by a cladding layer with a lower refractive index. When a light signal enters the core at an angle of incidence greater than the critical angle _c for the core-cladding interface, the light does not pass through the cladding but is instead reflected back into the core. This process repeats as the light pulse travels along the length of the fibre, allowing signals to be transmitted over long distances with minimal loss of intensity. The phenomenon of total internal reflection occurs only when light travels from a denser medium to a rarer medium and the angle of incidence exceeds the critical angle defined by the ratio of the refractive indices of the two media.

Explanation

In Microsoft Word, the Enter key serves as the command to end the current paragraph and move the cursor to the start of the next line. Pressing this key inserts a hard return or paragraph break into the document, which the software interprets as the completion of one block of text and the beginning of a new one. This is the standard operational method for manual line advancement and structural organization within the word processing interface.

Explanation

Potassium nitrate (KNO₃), commonly known as saltpeter, is a powerful oxidizing agent that plays a critical role in the pyrotechnic industry. It is a primary component of black powder, which is the traditional propellant used in firecrackers. In this application, potassium nitrate provides the oxygen necessary for the rapid combustion of sulfur and charcoal. Upon ignition, the chemical reaction releases a large volume of hot gases and energy, creating the characteristic explosion and sound associated with firecrackers. Its ability to decompose and release oxygen at high temperatures makes it indispensable for manufacturing various commercial explosives and fireworks.

Explanation

Steel is an alloy, which is a metallic mixture or solid solution consisting primarily of the element iron and a small percentage of carbon, typically ranging from 0.02 percent to 2.1 percent by weight. Allotropy is a specific property of certain chemical elements that allows them to exist in two or more different physical forms in the same state, such as different molecular structures or crystal lattices. Since steel is a composite material made of multiple different elements rather than a pure chemical element, it cannot be classified as an allotrope. Allotropes are strictly different structural modifications of a single element, whereas steel is a human-made mixture designed to enhance mechanical properties like strength and durability.

Explanation

The three R's represent the waste hierarchy used in environmental management to conserve resources and minimize waste. Reduce stands for minimizing the volume of waste generated by consuming less and choosing products with minimal packaging. Reuse involves finding alternative uses for items or using them multiple times instead of discarding them after a single use. Recycle refers to the process of collecting and processing materials that would otherwise be thrown away as trash and turning them into new products. This hierarchy prioritizes waste prevention and resource efficiency to reduce the overall burden on the environment.

Explanation

Explanation

The Arogya Raksha scheme was launched by the Government of Andhra Pradesh in January 2017 to provide comprehensive health insurance coverage to families belonging to the Above Poverty Line (APL) category. Unlike the NTR Vaidya Seva which targeted the poor, this scheme was designed to protect the middle class and those not covered by other government health initiatives. Under this scheme, individuals could avail themselves of medical benefits by paying a nominal premium of 100 rupees per month or 1200 rupees per year. It offered coverage for 1044 diseases and medical procedures, providing a health insurance cover of up to 2 lakh rupees per annum per individual, accessible through a network of government and empanelled private hospitals.

Explanation

A standard association football match consists of two equal halves of 45 minutes each, as stipulated by Law 7 of the Laws of the Game maintained by the International Football Association Board (IFAB). This results in a total base playing time of 90 minutes for a professional match. While the referee may add time at the end of each half to compensate for substitutions, injuries, or other stoppages, the official regulated duration for one-half of the game is 45 minutes.

Explanation

Explanation

The New Oxford Shakespeare, a major scholarly edition published in late 2016, introduced significant changes to the traditional chronology of William Shakespeare's plays based on modern stylometric analysis and Big Data. One of the most notable revisions concerned Hamlet. While scholars had long dated the play to approximately 1599-1601, the new research suggested it was written much earlier, around 1589-1590. The editors argued that Shakespeare himself was the author of the early version of the play often referred to as the Ur-Hamlet, which was previously attributed by many to Thomas Kyd. This redating shifted Hamlet from Shakespeare's mature period to the very beginning of his career as a playwright, fundamentally changing the academic understanding of his development.

As a cornerstone of the United States' defense diplomacy in Southeast Asia, it serves as a critical platform for multinational military cooperation and regional stability.

Explanation

Gurudwara Panja Sahib is situated in Hasan Abdal, located in the Punjab province of Pakistan. It is considered one of the holiest sites in Sikhism because it is associated with the founder of the religion, Guru Nanak Dev. The name of the shrine is derived from the word panja, which means palm or handprint. According to Sikh tradition, during Guru Nanak's visit to the area in 1521, a local saint named Wali Qandhari rolled a large boulder down a hill to crush him. Guru Nanak is said to have stopped the boulder with his open hand, leaving a permanent handprint on the stone. This sacred rock is still preserved within the gurudwara complex and attracts thousands of pilgrims annually, especially during the festival of Baisakhi.

Explanation

Wilhelm Conrad Röntgen, a German physicist, discovered X-rays on November 8, 1895. While conducting experiments to investigate the external effects of high-voltage vacuum tubes, specifically Crookes tubes, he noticed that a screen coated with barium platinocyanide in his laboratory began to fluoresce. This occurred even though the tube was entirely encased in heavy black cardboard to block visible light. He concluded that a new, invisible type of radiation was being emitted that could penetrate solid objects. Because the nature of these rays was initially unknown, he designated them as X-rays. For this monumental achievement, which laid the foundation for modern diagnostic radiology, Röntgen was awarded the first-ever Nobel Prize in Physics in 1901.

Explanation

Her leadership has been central to the political history of the nation and has been marked by a focus on economic development and the maintenance of strong bilateral ties with India.

Explanation

The tertiary sector, also known as the service sector, consists of activities that provide services to businesses and consumers rather than producing tangible physical goods. Courier services involve the transport and delivery of documents and packages, which falls under the communication and logistics sub-category of the service industry. Because courier companies facilitate trade and information exchange through specialized delivery systems without manufacturing any products or extracting natural resources, they are fundamentally classified as a service-oriented activity within the tertiary sector.

Explanation

A direct tax is a form of taxation where the liability to pay the tax and the actual economic burden of the tax fall on the same entity or individual, meaning it cannot be shifted to others. Income tax is a direct tax levied on the personal income of individuals. Wealth tax is a direct tax charged on the net wealth of individuals and companies; while it was abolished in the 2015 Union Budget of India, it remains conceptually a direct tax. Corporate tax is a direct tax imposed on the profits earned by businesses and corporations. Since all the specific taxes mentioned in the other options are classified as direct taxes, the selection indicating that none of them fall outside this category is correct.

Explanation

Fundamental Rights are considered justiciable in nature because they are legally enforceable by the courts in the event of their violation. Article 32 of the Indian Constitution empowers the Supreme Court to issue writs for the enforcement of these rights, making the right to move the court itself a Fundamental Right. Similarly, Article 226 provides the High Courts with the authority to protect these rights. This legal backing ensures that any law or executive action that contravenes Fundamental Rights can be declared null and void by the judiciary, providing a direct remedy to the citizens.

Explanation

The 42nd Amendment Act, 1976, is formally known as the Mini Constitution because it introduced the most extensive and significant changes to the Indian Constitution since its adoption. Passed during the National Emergency under the government of Indira Gandhi, it implemented the recommendations of the Swaran Singh Committee. This amendment modified the Preamble to include the terms Socialist, Secular, and Integrity. It also introduced Part IV-A, which established the Fundamental Duties of citizens under Article 51A. The amendment was so vast that it affected the powers of the judiciary, the relationship between the Center and the States, and the precedence of Directive Principles of State Policy over Fundamental Rights, effectively rewriting large portions of the constitutional framework.

Explanation

The Battle of Plassey was fought on June 23, 1757, on the banks of the Bhagirathi River in Bengal. Siraj ud-Daulah, the last independent Nawab of Bengal, was defeated by the British East India Company forces led by Robert Clive. The victory was facilitated by a secret alliance between Clive and Mir Jafar, the Nawab's commander-in-chief, who defected during the battle. This engagement was a turning point in Indian history as it paved the way for British political and economic dominance over the Indian subcontinent, starting with the control of the rich province of Bengal.

Explanation

The Alps are the highest and most extensive mountain range system that lies entirely within Europe, stretching approximately 1,200 kilometers across eight Alpine countries. These countries include France, Switzerland, Monaco, Italy, Liechtenstein, Austria, Germany, and Slovenia. Formed over tens of millions of years by the collision of the African and Eurasian tectonic plates, the range features prominent peaks such as Mont Blanc, which is the highest point in the system. The Alps significantly influence the European climate and serve as a major geographical barrier and a primary source of water for many of the continent's major rivers.

Explanation

The Inter Tropical Convergence Zone (ITCZ) is a broad belt of low pressure located in equatorial latitudes where the Northeast trade winds from the Northern Hemisphere and the Southeast trade winds from the Southern Hemisphere meet. This convergence of air masses leads to large-scale upward motion, resulting in the formation of convective clouds and frequent thunderstorms. Because it follows the position of the thermal equator, the ITCZ shifts north and south of the geographic equator throughout the year according to the seasonal migration of the sun. This movement is a primary driver of the monsoon systems in various parts of the world, including South Asia.

Explanation

Mycoplasma are a genus of bacteria that are uniquely characterized by the complete absence of a cell wall. They are the smallest known free-living organisms and belong to the kingdom Monera. Instead of a rigid cell wall, their cellular contents are enclosed by a three-layered plasma membrane that contains sterols, which provide a degree of structural integrity. The lack of a cell wall makes Mycoplasma pleomorphic, meaning they can assume various shapes, and renders them naturally resistant to many common antibiotics that function by inhibiting the synthesis of bacterial cell walls.

Explanation

Mitochondria are double-membraned organelles found in eukaryotic cells that serve as the primary site of aerobic cellular respiration. They are famously known as the powerhouse of the cell because they convert chemical energy from nutrients into Adenosine Triphosphate (ATP), which acts as the main energy currency for various cellular metabolic activities. This energy production occurs through the oxidation of glucose and fatty acids within the mitochondrial matrix and across the inner membrane. The inner membrane is highly folded into structures called cristae, which significantly increase the surface area available for the enzymes involved in the electron transport chain and oxidative phosphorylation. Additionally, mitochondria are semi-autonomous organelles that possess their own circular DNA and ribosomes, allowing them to synthesize some of their own proteins and replicate independently within the cell.

Explanation

Pneumatophores are specialized respiratory roots found in halophytic plants, such as mangroves, which grow in saline and waterlogged soils. In these environments, the soil is anaerobic and lacks sufficient oxygen for root cells to carry out metabolic activities. To overcome this, pneumatophores grow vertically upwards from the underground root system, emerging above the water or mud surface. These roots contain numerous small pores called lenticels or pneumathodes that allow for the direct exchange of gases, enabling the plant to absorb atmospheric oxygen and transport it to the submerged parts of the root system for respiration.

Explanation

Pitch is the characteristic of sound that enables the human ear to distinguish between a shrill sound and a grave or deep sound. It is directly determined by the frequency of the sound wave, which represents the number of complete vibrations or oscillations per unit of time. A higher frequency results in a higher number of vibrations reaching the ear per second, which the brain interprets as a higher pitch. Conversely, a lower frequency corresponds to a lower pitch. This physical relationship remains the fundamental basis for how the human auditory system perceives the tonal quality of sound.

Explanation

The photoelectric effect refers to the emission of electrons from a metal surface when light of a sufficient frequency strikes it. This phenomenon provides definitive evidence for the particle nature of light because it can only be explained by viewing light as a stream of discrete energy packets called photons. According to Albert Einstein's explanation, each photon carries a specific energy given by E = h ν, where h is Planck's constant and ν is the frequency. When a photon hits an electron, it transfers its energy in a one-to-one collision. The fact that electron emission depends on the light's frequency rather than its intensity, and occurs without a time lag, confirms that light interacts with matter as individual particles rather than continuous waves.

Explanation

Charles Babbage is widely regarded as the Father of Modern Computer due to his pioneering work in designing the first mechanical computing devices. In the 1830s, he developed the concept of the Analytical Engine, which was the first design for a general-purpose computer. This machine incorporated the fundamental logical structure used in today's computers, including a central processing unit (which he called the mill), a memory unit (the store), and the ability to be programmed using punched cards. His visionary approach to automated calculation and programmable logic provided the essential blueprint upon which all modern electronic computers were eventually built.

Explanation

CaOCl₂ is the chemical formula for calcium hypochlorite, which is commonly known as bleaching powder. It is produced on an industrial scale by the action of chlorine gas on dry slaked lime, represented by the chemical reaction Ca(OH)₂ + Cl₂ → CaOCl₂ + H₂O. This compound is widely used as a bleaching agent in the textile and paper industries for decolorizing materials and is also utilized as a powerful disinfectant for purifying drinking water because it acts as a strong oxidizing agent. It is often referred to as calcium oxychloride or chloride of lime in chemical contexts.

Explanation

Elements within the same group of the periodic table share the same number of valence electrons, which are the electrons located in the outermost shell of an atom. The periodic table is organized such that vertical columns contain elements with identical outer shell electronic configurations, leading to similar chemical properties and reactivity patterns. For instance, all elements in Group 1 have one electron in their outermost shell, while all elements in Group 18 have a full complement of electrons in their outermost shell. This recurring configuration is the fundamental basis for the periodic law.

Explanation

Nickel is a primary cause of allergic contact dermatitis, which is an inflammatory skin condition. When the skin comes into contact with nickel-containing objects such as jewelry, zippers, or coins, the metal can release nickel ions that penetrate the skin. This triggers a Type IV hypersensitivity reaction, where the immune system identifies the nickel as a foreign allergen. This immune response leads to localized symptoms including redness, itching, scaling, and skin eruptions. It is one of the most common causes of contact allergies worldwide, particularly in individuals with frequent occupational or personal exposure to metallic alloys.

Explanation
