Explanation

The Vernacular Press Act was enacted in 1878 during the viceroyalty of Lord Lytton to curtail the freedom of the Indian-language press. The legislation was introduced to suppress growing criticism of British policies, particularly concerning the Second Anglo-Afghan War and the government's handling of the Great Famine. Known as the Gagging Act, it empowered district magistrates to demand bonds from publishers to ensure they did not print material that could incite disaffection against the government. The act was discriminatory as it applied only to vernacular publications and exempted English-language newspapers. Its implementation famously led the Amrita Bazar Patrika to convert from a Bengali to an English-language newspaper overnight to escape the legal restrictions.

Explanation

Hard rubber is an insulator because its valence electrons are tightly bound within its molecular structure, leaving no free electrons available to move and carry an electric charge. Electrical conductivity requires the movement of charge carriers, such as electrons or ions, but in insulators like hard rubber, the energy required to move an electron from the valence band to the conduction band is extremely high. This significant forbidden energy gap results in very high electrical resistivity, which effectively blocks the flow of electricity through the material under standard conditions.

Explanation

Article 19 of the Constitution of India guarantees six fundamental freedoms to all citizens. These include the right to freedom of speech and expression, the right to assemble peaceably and without arms, the right to form associations or unions or co-operative societies, the right to move freely throughout the territory of India, the right to reside and settle in any part of the territory of India, and the right to practise any profession or to carry on any occupation, trade, or business. Although the Constitution originally provided for seven freedoms, the right to acquire, hold, and dispose of property was deleted by the 44th Amendment Act in 1978 and converted into a legal right under Article 300A. These six freedoms are protected against only state action and are subject to reasonable restrictions on grounds such as the sovereignty and integrity of India, security of the state, and public order.

Her leadership at the Kanpur session followed her extensive involvement in the Non-Cooperation Movement and the Khilafat Movement.

Explanation

The Executive branch is tasked with the administration and enforcement of laws and policies. In a democratic framework, the executive is responsible for the day-to-day management of state affairs and ensuring that the statutes enacted by the legislative body are put into practice. This branch includes both the political executive, such as the President or Prime Minister and the Council of Ministers, and the permanent executive, consisting of the civil services or bureaucracy. Through various departments and administrative agencies, the executive issues regulations, manages public services, and oversees the operational aspects of government functions to achieve the objectives set by law.

Explanation

Secondary production is defined as the rate of formation of new organic matter by consumers. Unlike primary producers such as plants that synthesize food through photosynthesis, secondary producers are heterotrophs that generate biomass by consuming primary producers. Herbivores occupy the second trophic level in a food chain and are the first group of organisms to convert plant matter into animal biomass. Because they facilitate the initial transfer of energy from the autotrophic level to the rest of the heterotrophic community, herbivores are specifically designated as secondary producers in ecological terminology.

Explanation

Barley is a prominent Rabi crop in North India, traditionally sown at the beginning of winter between October and December. It requires a cool climate during its vegetative growth phase and a warm, dry environment for ripening and harvesting, which typically occurs from March to May. In the agricultural landscape of states like Rajasthan, Uttar Pradesh, and Haryana, barley is a vital cereal grain that benefits from the western disturbances and winter rainfall, making it a staple of the winter cropping season.

Explanation

Mango showers refer to the pre-monsoon rainfall that occurs towards the end of the summer season, typically during the months of March to May. This phenomenon is a common feature in the coastal regions of South India, specifically in Kerala and parts of Karnataka. These light rains are climatically significant as they occur just before the onset of the southwest monsoon. They are named mango showers because they play a crucial role in the early ripening of mangoes, ensuring the fruit matures properly and remains on the tree. These showers are generally the result of localized thunderstorms and convectional activity caused by the intense heat of the summer months.

Explanation

The first phase of the Green Revolution, which occurred from the mid-1960s to the mid-1970s, was characterized by the introduction of High Yielding Variety (HYV) seeds, particularly for wheat. The successful cultivation of these seeds required intensive inputs, including assured irrigation facilities and heavy use of chemical fertilizers and pesticides. Due to these high capital requirements and the need for sophisticated water management, the initial implementation was restricted to regions that were already agriculturally advanced and possessed affluent farming communities. Punjab, Tamil Nadu, and Andhra Pradesh were the primary states that met these criteria, as they had better-developed irrigation networks and the financial capacity to adopt the new technology. This strategic concentration ensured higher productivity gains in areas where the infrastructure could support the biological requirements of the new seed varieties.

Explanation

A plateau is an elevated flat land that rises sharply above the surrounding area on at least one side. It is characterized by a relatively level upper surface, which is why it is commonly referred to as a tableland. These landforms can vary in height from a few hundred meters to several thousand meters and are typically formed by geological forces such as the cooling of lava layers, the collision of tectonic plates, or the persistent erosion of surrounding soil and rock by water and wind.

Explanation

Baishakhi, also known as Vaisakhi, is a significant historical and religious festival in Sikhism that is celebrated annually in the month of April. It marks the first day of the month of Vaisakh according to the Nanakshahi solar calendar, typically falling on April 13 or 14 each year. The festival commemorates the formation of the Khalsa Panth by the tenth Sikh Guru, Guru Gobind Singh, in the year 1699 at Anandpur Sahib. Beyond its religious importance, Baishakhi serves as a traditional harvest festival in Northern India, particularly in Punjab and Haryana, marking the time when farmers gather the Rabi crops. It is celebrated with great fervor through community gatherings, Nagar Kirtan processions, and traditional folk dances such as Bhangra and Gidda.

Explanation

Chola inscriptions categorize land based on its usage and the status of the recipients. The term Devadana, also frequently referred to as Tirunamattukkani in various records, specifically denotes land that was gifted to temples. These grants were a significant aspect of the Chola agrarian and religious economy, as the revenue derived from such lands was dedicated to the maintenance of the temple, the performance of daily rituals, and the support of the temple staff. By gifting Devadana lands, the Chola monarchs and local assemblies ensured that temples functioned as major socio-economic hubs within the kingdom, facilitating large-scale irrigation projects and providing employment to various sections of society.

Explanation

Thaipusam is a major Hindu festival celebrated by the Tamil community during the Tamil solar month of Thai, which usually falls between January and February. The festival takes place on the full moon day when the Pusam star is at its highest point. It is dedicated to Lord Murugan, the son of Shiva and Parvati. The occasion commemorates the day Goddess Parvati gave Murugan a divine spear, known as the Vel, to destroy the demon Soorapadman and his brothers. Devotees observe the festival through various acts of devotion and penance, such as carrying a Kavadi, which is a physical burden or decorated canopy, and performing ceremonial piercings to demonstrate faith and seek blessings.

Explanation

The Goods and Services Tax (GST) was launched in India on 1 July 2017, following a historic midnight session in Parliament. This comprehensive indirect tax reform was implemented through the 101st Constitution Amendment Act, 2016. It replaced multiple central and state taxes, including central excise duty, service tax, value-added tax (VAT), and various surcharges and cesses. The primary objective of the roll-out was to create a unified common national market by streamlining the taxation process and eliminating the cascading effect of taxes on the final price of goods and services.

Explanation

Nagaram was the administrative assembly or organization composed primarily of merchants and traders as mentioned in Pallava and Chola inscriptions. These bodies functioned predominantly in urban trade centers and commercial towns where the mercantile community held significant influence. The Nagaram was responsible for managing the local affairs of the market, regulating trade practices, and collecting commercial taxes. Its existence highlights the specialized local governance structures that catered to the economic needs of urban settlements and facilitated organized commerce during the early medieval period in South India.

Explanation

The troposphere is the lowest and densest layer of the Earth's atmosphere, containing approximately 80 percent of the atmosphere's mass and nearly all its water vapor. Its thickness varies significantly with latitude and season due to the differential heating of the Earth's surface. At the equator, where solar heating is most intense, strong convective currents push the layer upward to a height of about 18 km. Conversely, at the poles, the air is colder and denser, causing the troposphere to extend only to about 8 km. When considering these geographical variations, the global mean or average height of the troposphere is 13 km. This layer is critical for life as it is the region where almost all weather phenomena, such as cloud formation and precipitation, occur.

Explanation

Milk of magnesia is the common name for an aqueous suspension of magnesium hydroxide, represented by the chemical formula Mg(OH)₂. It is a weak base that is widely used in medicine as an antacid to neutralize excess stomach acid and as a laxative. Because it is a basic substance, its position on the pH scale is above the neutral value of 7. Specifically, milk of magnesia has a pH value of approximately 10.5, which is often rounded to 10 in standard scientific contexts and textbooks. This alkaline nature is essential for its function, as it allows the hydroxide ions to react with and neutralize the hydronium ions in gastric juice, thereby relieving acidity.

Explanation

In the Indian parliamentary system, the Constitution provides for a division between the nominal executive and the real executive. Under Article 74(1), there is a Council of Ministers with the Prime Minister at the head to aid and advise the President in the exercise of their functions. While the President is the formal head of the state in whom all executive powers are theoretically vested by Article 53, these powers are exercised only on the advice of the Council of Ministers. Therefore, the Prime Minister, as the leader of the Council of Ministers, serves as the real executive head (de facto executive) of the government, wielding the actual administrative and political power of the Union.

Explanation

Explanation

The numerical value of a physical quantity is defined as its magnitude. In physics, any measurable property is expressed as the product of a numerical value and a unit, represented by the formula Q = n × u. In this expression, n is the numerical value or magnitude, and u is the unit of measurement. The magnitude provides a quantitative description of the size, extent, or amount of the physical quantity relative to a standard reference. For instance, in a measurement of 50 kilograms, the number 50 is the magnitude that specifies how many units of mass are present. While vector quantities additionally require direction, the numerical component specifically denotes the magnitude.

Explanation

On International Women's Day in March 2022, the Tripura government announced a 33 percent reservation for women in all state government jobs. This policy was introduced to enhance women's participation in the state workforce and promote gender equality across various administrative departments. By securing a specific quota in public employment, the state aimed to foster socio-economic empowerment and provide women with better access to career opportunities within the government sector. This initiative aligns with broader national efforts to increase female representation in governance and public service.

Explanation

The Paramhans Mandali was a secret socio-religious society founded in Bombay in 1849 by Dadoba Pandurang and Ram Balkrishna Jayakar. It was one of the earliest reformist organizations in Western India dedicated to the abolition of the caste system and the promotion of monotheistic worship. The Mandali operated on the philosophy that there is only one God and that all human beings belong to a single caste. To demonstrate their rejection of caste distinctions, members were required to consume food and water prepared or touched by people of lower castes during their secret meetings. This organization was deeply influenced by the Manav Dharma Sabha and served as a precursor to later social reform movements in Maharashtra, such as the Prarthana Samaj.

Explanation

According to Law 9 of the Laws of the Game, the ball is considered in play at all times as long as it remains within the field of play boundaries. This includes instances where the ball rebounds off the goalposts, crossbar, or corner flagposts and stays within the touch lines and goal lines. Because the ball has not wholly crossed the boundary lines on the ground or in the air, and play has not been stopped by the referee, the ball remains active. In scenarios where the ball strikes a match official and remains on the field without triggering a specific stoppage like a change in possession or a goal, it continues to be in play.

Explanation

Explanation

In the framework of Indian economic planning, modernisation was defined by two primary dimensions: the adoption of new technology to increase the production of goods and services and a progressive change in social outlook, such as the recognition of equal rights for women. Planners and policymakers explicitly distinguished modernisation from Westernisation. The goal was to achieve economic growth and social justice through scientific advancement and rational social reforms without requiring the population to abandon indigenous traditions or adopt Western lifestyles, clothing, or cultural habits. Modernisation aimed at structural transformation of the economy and self-reliance, treating technological progress as a tool for development rather than a mandate for cultural imitation.

Explanation

Robert Hooke, the English polymath and experimental philosopher, discovered the fifth star in the Trapezium cluster in 1664. The Trapezium is a tight cluster of stars located at the heart of the Orion Nebula (M42). While Galileo Galilei had initially recorded three stars in the cluster in 1617 and Christiaan Huygens identified a fourth in 1656, Hooke used his improved telescopic equipment to resolve the fifth component. This discovery was a testament to the increasing quality of optical instruments in the mid-seventeenth century. The star Hooke observed is known in modern stellar catalogues as component E of the Theta1 Orionis system.

Explanation

Kwashiorkor is a severe form of malnutrition specifically caused by a deficiency of protein in the diet. Weak bones and muscles are the result of calcium deficiency, as calcium is the primary mineral required for building and maintaining bone density and facilitating muscle contractions. Anaemia is a condition where the body lacks enough functional red blood cells or hemoglobin to carry oxygen to tissues, which is most commonly caused by iron deficiency. Goitre refers to the abnormal enlargement of the thyroid gland, which occurs when there is an insufficient intake of iodine.

Explanation

The Battle of Plassey took place on 23 June 1757 at Palashi, on the banks of the Bhagirathi-Hooghly River in Bengal. It was a decisive engagement between the British East India Company, led by Robert Clive, and the Nawab of Bengal, Siraj-ud-Daulah, who was supported by French allies. The British victory was largely secured through a secret alliance with Mir Jafar, the Nawab's commander-in-chief, who remained inactive during the battle. This event is historically significant as it marked the beginning of British political and territorial dominance in the Indian subcontinent, effectively transitioning the East India Company from a mere trading entity to a ruling power.

By expanding to 126 additional cities in April 2022, the initiative sought to provide comprehensive social protection and holistic development to a larger number of urban street vendors, ensuring their long-term economic stability and well-being.

Explanation

Uttarakhand is located in the Himalayan region, where the varying altitudes and cold climatic conditions support the growth of montane forests. Coniferous trees, such as Chir Pine, Deodar, Blue Pine, Spruce, and Silver Fir, are predominantly found in these high-altitude zones, typically ranging from 1,500 to 3,500 meters. These trees are characterized by their needle-like leaves and cone-bearing structures, which are adaptations to the heavy snowfall and low temperatures characteristic of the Himalayan mountain range within the state.

Explanation

Natural acid-base indicators are substances derived from natural sources, such as plants, that change color when exposed to acidic or basic environments. Litmus is a water-soluble mixture of different dyes extracted from lichens, primarily Roccella tinctoria, and is used to indicate acidity by turning red and basicity by turning blue. Turmeric is a spice obtained from the rhizomes of Curcuma longa that contains the chemical curcumin; it functions as a natural indicator by maintaining its yellow color in acidic or neutral solutions while turning a deep reddish-brown in basic solutions. Because both substances are plant-based and undergo characteristic color changes in response to pH levels, they are both categorized as natural indicators.

Explanation

The NAMASTE scheme, which stands for National Action for Mechanised Sanitation Ecosystem, is a joint initiative of the Ministry of Social Justice and Empowerment and the Ministry of Housing and Urban Affairs launched in August 2022. Its primary goal is to achieve zero fatalities in sanitation work across India by eliminating hazardous cleaning practices and ensuring that no worker comes into direct contact with human waste. To achieve this, the scheme focuses on formalizing the sector by identifying sewer and septic tank workers and providing them with occupational safety training and health insurance. Furthermore, the scheme aims to provide sustainable livelihoods by collectivizing sanitation workers into Self-Help Groups (SHGs) and empowering them to own and operate sanitation enterprises through capital subsidies and access to mechanised equipment, effectively transitioning them from manual laborers to entrepreneurs.

Explanation

Plasmids are small, circular, double-stranded DNA molecules that exist independently of the bacterial chromosome. They function as extra-chromosomal genetic material that provides specific survival advantages to the host bacteria. By carrying specialized genes, such as those for antibiotic resistance, heavy metal tolerance, or the production of virulence factors, plasmids confer unique phenotypic characteristics that are not encoded by the main genomic DNA. These traits allow bacteria to adapt and survive in diverse and often hostile environments. The ability of plasmids to replicate independently and be transferred between bacteria through processes like conjugation further facilitates the rapid spread of these beneficial phenotypic traits within bacterial populations.

Explanation

The Election Commission of India functioned as a single-member body from its inception in 1950 until October 15, 1989. On October 16, 1989, the President of India appointed two additional Election Commissioners for the first time. This expansion was prompted by the increased workload resulting from the 61st Constitutional Amendment Act of 1988, which lowered the minimum voting age from 21 to 18 years, thereby significantly increasing the size of the electorate. While the Commission briefly reverted to a single-member body in January 1990, the October 1989 appointment remains the historical first instance of it being a multi-member body.
