SSC CGL Tier 1 2016 General Awareness Questions with Solutions

Explanation

Xylem is the primary vascular tissue in plants dedicated to the conduction of water and dissolved minerals from the roots to the aerial parts, such as stems and leaves. It forms a continuous system of conduits throughout the plant, utilizing specialized cells called tracheids and vessel elements. The movement of water through the xylem is driven by physical forces, most notably transpiration pull, where the evaporation of water from leaf surfaces creates a negative pressure that draws water upward from the soil. Additionally, root pressure contributes to this upward flow, ensuring that the plant receives the necessary hydration and inorganic nutrients required for photosynthesis and metabolic activities.

Explanation

Following the Andhra Pradesh Reorganisation Act, 2014, the state of Andhra Pradesh was bifurcated to create Telangana, leaving Hyderabad as the shared capital for a period of up to ten years. To establish a new administrative center, the state government selected the Amaravati region in Guntur district on the banks of the Krishna River. The foundation stone for this greenfield capital city was laid by Prime Minister Narendra Modi on October 22, 2015. By early 2016, Amaravati was officially recognized as the new capital of Andhra Pradesh, intended to serve as the seat of the state government, legislature, and high court.

Explanation

The Karnataka State Government abolished agricultural income tax in its state budget for the financial year 2016-17, presented by Chief Minister Siddaramaiah in March 2016. Before this decision, the tax was primarily levied on income derived from plantation crops such as coffee, tea, rubber, and cardamom. The abolition was intended to provide financial relief to the farming and plantation community, which was grappling with price fluctuations and unfavorable climatic conditions. By removing this tax, Karnataka aimed to simplify the tax regime and reduce the compliance burden on growers across the state.

Explanation

The matrix method is a mathematical and algebraic tool used for solving systems of linear equations and organizing data into rectangular arrays, but it is not a recognized economic approach for calculating national income. National income estimation is fundamentally based on measuring the flow of goods, services, and money within an economy through production, income, or expenditure frameworks. The matrix method lacks the macroeconomic theoretical basis required to aggregate a nation's total economic output or income.

Explanation

According to Article 342 of the Constitution of India, the power to amend the list of Scheduled Tribes resides with the Parliament. While the President of India has the authority under Article 342(1) to specify the tribes or tribal communities deemed to be Scheduled Tribes in the initial notification for a state or union territory, any subsequent inclusion or exclusion from this list must be done by a law enacted by Parliament. Article 342(2) explicitly states that Parliament may by law include in or exclude from the list of Scheduled Tribes specified in a notification any tribe or tribal community, and once the Presidential notification is issued, it cannot be varied by any subsequent notification except by an Act of Parliament.

Explanation

Project Sankalp was an initiative launched by the Employees State Insurance Corporation (ESIC) under the Ministry of Labour and Employment to combat the spread of HIV/AIDS. The primary objective of this project was to provide education and awareness regarding the prevention of HIV/AIDS among industrial workers and their families. By integrating HIV/AIDS prevention programs into the existing healthcare infrastructure of ESIC, the project aimed to reduce the vulnerability of the workforce to the infection and ensure access to counseling and treatment services within the organized sector.

Explanation

The Ring of Fire, also referred to as the Circum-Pacific Belt, is a 40,000-kilometer horseshoe-shaped zone characterized by high volcanic and seismic activity encircling the Pacific Ocean. This region is home to approximately 75 percent of the world's active volcanoes and the vast majority of global earthquakes. Its existence is the result of plate tectonics, specifically the movement and collision of several lithospheric plates, such as the Pacific, Nazca, and Philippine Sea plates. Along these boundaries, subduction zones occur where one plate slides beneath another, leading to the formation of deep-sea trenches and volcanic arcs. This continuous tectonic interaction makes the Pacific basin the most geologically active area on Earth.

Explanation

Agrobacterium tumefaciens is a soil-borne, Gram-negative bacterium responsible for crown gall disease in many species of dicotyledonous plants. The infection process involves the transfer of a specific piece of DNA, called T-DNA, from the bacterium's tumor-inducing (Ti) plasmid into the nuclear genome of the host plant cell. This transferred DNA contains genes that encode for the production of unusual amino acids called opines, which the bacteria use as a carbon and nitrogen source, as well as genes that trigger the overproduction of plant hormones such as auxins and cytokinins. The resulting hormonal imbalance leads to uncontrolled cell proliferation, manifesting as large, tumor-like swellings or galls typically located at the crown of the plant, which is the interface between the root and the stem. This natural ability to cross-kingdom gene transfer has made Agrobacterium tumefaciens an essential tool in plant biotechnology for the creation of genetically modified crops.

Explanation

The Eustachian tube, also known as the auditory tube or pharyngotympanic tube, is a small canal that connects the middle ear to the nasopharynx, which is the upper part of the throat behind the nasal cavity. It is an essential anatomical component of the ear because it regulates the air pressure within the middle ear, ensuring it matches the external atmospheric pressure. This equalization allows the eardrum to vibrate correctly for sound perception. The tube also serves to drain normal secretions and mucus from the middle ear into the throat. It typically remains closed but opens during activities like swallowing, yawning, or sneezing to maintain pressure balance and protect the middle ear from fluid buildup.

Explanation

The cerebellum is a vital component of the hindbrain that functions as the primary center for motor control and coordination. It receives sensory information from the spinal cord, vestibular system, and cerebral cortex to monitor the body's position and movement. Although it does not initiate voluntary muscle contraction, it ensures that movements are executed with precision, smoothness, and accurate timing. It is specifically responsible for maintaining posture, equilibrium, and muscle tone, allowing for the fine-tuning of complex motor activities such as walking or manual dexterity.

Explanation

Frequency is defined as the number of cycles or periodic reversals completed by an electric current per second. Direct current (DC) is characterized by the flow of electric charge in only one constant direction. Unlike alternating current (AC), which oscillates back and forth and follows a sine wave pattern, the magnitude and direction of direct current remain steady over time. Because there are no oscillations or cycles occurring in a DC circuit, the number of cycles per second is exactly zero. Mathematically, since the period T of a constant signal is considered infinite, the frequency f = 1/T results in 0 Hz.

Explanation

The Yajurveda is the primary Veda dedicated to the performance of rituals and sacrifices. It serves as a practical manual for the Adhvaryu priest, who is responsible for the physical execution of the Vedic sacrifice or yajna. The text contains a collection of short prose mantras known as yajus, which are recited during the ritual acts, such as preparing the sacrificial ground, lighting the sacred fire, and offering oblations. It is divided into two main branches: the Shukla Yajurveda, which consists of the mantras themselves, and the Krishna Yajurveda, which includes the mantras along with prose explanations and detailed instructions on how to conduct the various ceremonies correctly.

Explanation

Methane (CH₄) is a significant greenhouse gas that contributes to the warming of the Earth's atmosphere by absorbing long-wave infrared radiation. While carbon dioxide (CO₂) is the most abundant anthropogenic greenhouse gas, methane is much more potent on a per-molecule basis, having a global warming potential many times higher than CO₂ over a 100-year period. It is released into the atmosphere through both natural sources like wetlands and human activities including livestock farming, rice cultivation, biomass burning, and the extraction of fossil fuels. The molecular structure of CH₄ allows it to vibrate in ways that capture heat energy radiating from the Earth's surface, effectively trapping it within the troposphere.

Explanation

The Central Statistical Organization (CSO) is the primary government agency responsible for coordinating statistical activities in India and maintaining statistical standards. Operating under the Ministry of Statistics and Programme Implementation, the CSO compiles and releases various macroeconomic indicators, including the National Income, Gross Domestic Product (GDP), and Gross National Product (GNP). It utilizes data from diverse sectors of the economy to prepare the National Accounts Statistics (NAS) annually, ensuring that the methodologies align with international frameworks like the System of National Accounts (SNA).

Explanation

Article 131 of the Constitution of India grants the Supreme Court original jurisdiction over disputes involving the federal structure of the country. This jurisdiction is exclusive, meaning no other court can entertain such cases, and it allows the Supreme Court to hear the matter in the first instance rather than through an appeal. This power specifically covers legal disputes between the Government of India and one or more States, or between two or more States. To qualify under this jurisdiction, the dispute must involve a question of law or fact on which the existence or extent of a legal right depends. This ensures the Supreme Court acts as the final arbiter in maintaining the constitutional balance between the Centre and the States.

Explanation

The phrase Satyameva Jayate, which translates to Truth alone triumphs, is a mantra from the ancient Indian scripture known as the Mundaka Upanishad. It is specifically found in the third Mundaka, first khanda, sixth verse (3.1.6). Following India's independence, it was adopted as the national motto of India on 26 January 1950. The slogan is inscribed in Devanagari script at the base of the Lion Capital of Ashoka at Sarnath, which constitutes the State Emblem of India. The full verse emphasizes that through truth, the path of the gods is opened, which sages travel to reach the supreme abode of truth.

Explanation

Granite is an intrusive igneous rock composed mainly of quartz, feldspar, and mica. Under the influence of intense heat and pressure during regional metamorphism, these minerals undergo recrystallization and mechanical deformation. The mineral grains segregate and realign into alternating dark and light layers, a process known as foliation or gneissic banding. This metamorphic transformation results in the formation of Gneiss. The resulting rock retains the chemical composition of the original granite but exhibits a new, banded crystalline structure that distinguishes it as a high-grade metamorphic rock.

Explanation

Natural gas is classified as a commercial source of energy because it is a commodity that is bought and sold in the market at a determined price. It serves as a vital energy source for industrial production, electricity generation, and transportation. Unlike non-commercial sources that are typically gathered for personal or subsistence use, natural gas requires extensive infrastructure for extraction, processing, and distribution through pipelines or tankers, involving formal economic transactions and large-scale commercial utility.

Explanation

The backward-bending supply curve is a phenomenon specifically observed in the labor market, representing the trade-off between labor and leisure. Initially, as the wage rate rises, the substitution effect encourages individuals to work more because the opportunity cost of leisure has increased. However, once the wage reaches a certain threshold, the income effect becomes dominant. At higher income levels, workers value leisure more and choose to work fewer hours while still maintaining a high standard of living. Since leisure is a normal good, the increase in real income leads to an increased demand for leisure and a corresponding decrease in the hours of labor supplied, causing the supply curve to bend backward at higher wage levels.

Explanation

Associative memory is formally known as Content Addressable Memory (CAM). Unlike standard random-access memory (RAM), which retrieves data based on a specific numerical address, CAM is designed to search its entire data storage in a single clock cycle based on the content of the data itself. When a user or system provides a data word, the CAM hardware compares it against all stored words simultaneously and returns the address of the matching location. This parallel search capability makes it exceptionally fast for specific tasks. It is primarily used in high-speed networking equipment for routing table lookups and in computer processors for managing Translation Lookaside Buffers (TLB) to speed up virtual-to-physical address translation.

Explanation

Doping is the deliberate addition of specific impurity atoms to a pure or intrinsic semiconductor to modify its electrical conductivity. In an intrinsic semiconductor, the number of free electrons and holes is relatively low at room temperature. By introducing trivalent impurities such as boron or indium, p-type semiconductors are formed where holes serve as the primary charge carriers. Alternatively, the addition of pentavalent impurities like phosphorus or arsenic creates n-type semiconductors where electrons become the majority charge carriers. This controlled modification allows for the creation of p-n junctions, which are the fundamental building blocks of modern electronic devices including diodes, transistors, and solar cells.

Explanation

The Kyoto Protocol is an international treaty that extends the 1992 United Nations Framework Convention on Climate Change (UNFCCC) that commits state parties to reduce greenhouse gas emissions. Adopted in 1997 in Kyoto, Japan, and entering into force in 2005, the protocol’s primary objective is to address global warming and climate change by setting legally binding emission reduction targets for developed countries. It operates on the principle of common but differentiated responsibilities, placing a heavier burden on developed nations because they are recognized as being more responsible for the current high levels of greenhouse gases in the atmosphere due to historical industrial activity.

Explanation

Founded in 1895 as Laurin | Klement, it is one of the world's oldest car manufacturers. In 1925, it was acquired by the industrial conglomerate Skoda Works, and since 1991, it has gradually become a wholly owned subsidiary of the Volkswagen Group. The Skoda Rapid, a sedan model mentioned in the question, was launched as a prominent entry in the mid-size sedan segment in various global markets, including India, reflecting the brand's Czech engineering and design heritage.

Explanation

Sattriya is a classical dance form that originated in the Sattras, which are Vaishnavite monasteries located in Assam. It was created by the 15th-century saint and scholar Srimanta Sankardev to propagate the Bhakti movement through mythological stories and dance dramas. This dance form was traditionally performed by male monks known as Bhokots as part of their daily religious rituals and remains deeply rooted in the cultural and spiritual fabric of the state. The Sangeet Natak Akademi officially recognized Sattriya as a classical dance in the year 2000, acknowledging its sophisticated grammar of movement, traditional Borgeet music, and unique Assamese costumes.

Explanation

Wang Yihan is a professional badminton player from China who was a former world number one and a dominant figure in the sport. During the 2016 Rio Olympics, she represented the Chinese national team as the silver medalist from the previous 2012 London Olympics and the reigning world number two. P. V. Sindhu defeated her in the quarterfinals with a score of 22-20, 21-19, which was a significant milestone in Sindhu's journey to becoming the first Indian woman to win an Olympic silver medal. Wang Yihan had a highly successful career representing China, including winning the World Championships in 2011 and multiple Uber Cup and Sudirman Cup titles before retiring later in 2016.

Explanation

Under the principle of collective responsibility enshrined in Article 164 of the Indian Constitution, the Council of Ministers is collectively responsible to the Legislative Assembly of the State. The budget, which includes the Annual Financial Statement and the Appropriation Bill, is the most crucial policy and financial measure of the government. Because the government cannot function without the legal authority to spend money, the passage of the budget is a fundamental test of its majority. If the budget is defeated on the floor of the Legislative Assembly, it signifies that the government has lost the confidence of the House. In such a scenario, the Chief Minister and the entire Council of Ministers must resign, as they no longer command the support of the legislature required to remain in office.

Explanation

Mahatma Gandhi started the newspaper Indian Opinion in 1903 while he was in South Africa. It was an essential tool for the Indian community to voice their grievances against racial discrimination and the oppressive laws of the colonial government. The paper was published from the Phoenix Settlement near Durban in English, Gujarati, Hindi, and Tamil. It served as a primary platform for Gandhi to propagate his philosophy of Satyagraha and non-violent resistance before his return to India in 1915. Through this publication, he effectively mobilized the Indian diaspora and kept the global community informed about the civil rights struggles in the region.

Explanation

The Kochi Water Metro project was launched in February 2016 as India's first integrated water transport system. This pioneering urban mobility project was initiated by Kochi Metro Rail Limited (KMRL) to connect the mainland of Kochi with ten nearby islands through a network of high-speed, fuel-efficient, and battery-powered ferries. The project was designed to utilize the extensive backwaters of Kerala to reduce traffic congestion on the roads and provide a cost-effective, sustainable transportation alternative for the island residents. It significantly improved regional connectivity and was developed with financial assistance from the German funding agency KfW, marking a major milestone in India's maritime and urban transport infrastructure.

Explanation

Meibomian glands, also known as tarsal glands, are specialized sebaceous glands located within the tarsal plates of the upper and lower eyelids. These glands secrete meibum, an oily substance that forms the outermost lipid layer of the tear film. This lipid layer is crucial for maintaining ocular health because it prevents the evaporation of the eye's tear film, provides a smooth optical surface, and prevents tears from spilling over the eyelid margins. Proper functioning of these glands is essential to prevent dryness and irritation of the ocular surface.

Explanation

India's first Post Office ATM was inaugurated at the Thyagaraya Nagar (T. Nagar) Head Post Office in Chennai on February 27, 2014. This launch was a significant part of the Department of Posts' IT modernization project, aimed at providing 24/7 banking services to postal savings account holders. The initiative paved the way for the transformation of the postal department into a more tech-savvy organization, eventually enabling interoperability with other commercial bank ATMs across the country.

Explanation

Andy Murray won the 2016 Wimbledon Men's Singles title, marking his second championship at the All England Club and his third Grand Slam title overall. He secured the victory by defeating Milos Raonic in the final in straight sets, with a score of 6–4, 7–6(7–3), 7–6(7–2). Murray's performance throughout the tournament was dominant, as he became the first British man to win multiple Wimbledon singles titles since Fred Perry in the 1930s. This victory was a highlight of a successful 2016 season for Murray, which eventually saw him reach the world number one ranking in the ATP standings.

Explanation

Vitamins are classified into two groups based on their solubility: fat-soluble and water-soluble. Water-soluble vitamins include Vitamin C and all the vitamins in the B-complex group. These vitamins dissolve easily in water and are generally not stored in the body for long periods. Instead, they are carried to the body's tissues, and any excess amounts are typically excreted through urine. Because they are not stored, the body requires a steady daily intake of Vitamin B and Vitamin C through dietary sources to maintain optimal health and facilitate various metabolic processes, such as energy production and immune function.

Explanation

A situation is described as Pareto-superior when an alternative allocation of resources exists that can improve the well-being of at least one person without reducing the well-being of any other person. This concept is central to the Pareto criterion in welfare economics, which evaluates the efficiency of different resource distributions. If such a change is possible, the move is called a Pareto improvement, and the resulting state is Pareto-superior to the previous one. This continues until no more such improvements can be made, at which point the situation reaches Pareto optimality or efficiency, where it is impossible to make someone better off without making someone else worse off.
