The question asks to identify the term for an object moving up to four times faster than the speed of sound. This involves understanding the classification of speeds relative to the speed of sound, often expressed using the Mach number.
Correct Option: C) supersonic — This term describes speeds greater than the speed of sound (Mach 1) and typically up to Mach 5. An object moving up to four times faster than the speed of sound (i.e., Mach 1 to Mach 4) falls within this category.
The question asks to identify the region where the Faraizi Movement, led by Haji Shariatullah, was active. This requires knowledge of the historical context and geographical spread of 19th-century socio-religious reform movements in British India.
Correct Option: D) The Faraizi Movement, led by Haji Shariatullah, was a significant socio-religious reform movement that originated and was primarily active in the region of Bengal during the 19th century. Its focus was on religious purification and resisting British influence and the exploitation by landlords.
The question asks for the base location of the Federation of Indian Associations (FIA), specifically referring to the one that elected Hemant Patel as President for the 2025–2026 term. This requires knowledge of prominent Indian diaspora organizations and their headquarters.
C) Chicago, USA. The Federation of Indian Associations (FIA) is a prominent umbrella organization for the Indian diaspora in the United States. While there are various FIA chapters, the one often referred to in national news for its leadership and large events (such as the India Day Parade in New York City) has its roots and significant presence in the Tri-State area (New York, New Jersey, Connecticut) and is headquartered in Chicago, USA, which is a major center for Indian-American community organizations.
The question asks for the definition of an acid according to the Brønsted-Lowry theory. This theory defines acids and bases based on their ability to donate or accept protons (H+ ions).
Correct Option: A) Donates a proton
According to the Brønsted-Lowry theory, an acid is defined as a proton (H+) donor. For example, in the reaction \( \text{HCl} + \text{H}_2\text{O} \rightarrow \text{H}_3\text{O}^+ + \text{Cl}^- \), hydrochloric acid (HCl) donates a proton to water (H2O), making HCl a Brønsted-Lowry acid.
The question asks about the global conference that led to the Convention on Biological Diversity (CBD). This requires knowledge of major international environmental conferences and their outcomes.
Correct Option: A) Earth Summit, 1992
The question asks for the full form of the abbreviation NGLV in the context of ISRO's rocket programme for 2025. This requires knowledge of current and upcoming ISRO projects and their associated terminology.
ISRO has been working on developing a new launch vehicle to replace its existing operational rockets like PSLV and GSLV in the long term. This new vehicle is intended to be more cost-effective, reusable, and capable of carrying heavier payloads. The official term used by ISRO for this future rocket programme is "Next Generation Launch Vehicle" (NGLV).
B) Next Generation Launch Vehicle
ISRO's future rocket programme aims to develop a cost-effective, reusable, and heavy-lift launch vehicle. This project is officially referred to as the Next Generation Launch Vehicle (NGLV). It is envisioned to replace the current operational launchers like PSLV and GSLV over time, offering enhanced capabilities and reduced launch costs.
The question asks about the primary objective of ISRO's Aditya-L1 mission. This requires knowledge of the mission's purpose, which is a key aspect of current affairs and space technology relevant for competitive exams.
Correct Option: A) Observe the Sun's outermost layer. The Aditya-L1 mission is India's first dedicated solar mission, designed to study the Sun's corona (outermost layer), chromosphere, and photosphere, as well as solar emissions and space weather phenomena. Its primary objective includes understanding the dynamics of the solar corona and the heating mechanism of the solar atmosphere.
The question asks to identify the type of memory that loses its stored data when power is removed. This characteristic is known as volatility. We need to distinguish between volatile and non-volatile memory types.
Correct Option: B) RAM is Random Access Memory, which is a volatile memory. This means it requires continuous power to retain the stored information. When the power supply is interrupted or turned off, all data stored in RAM is lost.
The question asks for the primary reason behind the formation of lagoons along the Eastern Coastal Plains of India. We need to analyze the geological and geomorphological processes that lead to lagoon formation, particularly in this region, and evaluate the given options.
D) Deposition by rivers and wave action along the coast is the main reason. Rivers bring vast quantities of sediment to the coast, and wave action, particularly longshore currents, redistributes and deposits this sediment to form sandbars and spits. These sandbars eventually enclose shallow areas of the sea, creating lagoons. This process is very prominent along the Eastern Coastal Plains due to the presence of large rivers like the Mahanadi, Godavari, Krishna, and Cauvery, which deposit huge amounts of alluvium.
The question asks to identify the specific scheme launched by the Chief Minister of Kerala in May 2025 for the education of migrant children. This requires knowledge of recent government initiatives in Kerala.
Correct Option: D) The scheme launched by the Chief Minister of Kerala in May 2025 to educate migrant children is named 'Jyothi'. This initiative aims to provide educational opportunities and support to children of migrant laborers residing in Kerala, ensuring they have access to schooling and can integrate into the state's education system.
