The question asks to identify a landform characterized as a flat or gently sloping surface created by river erosion, often featuring isolated resistant remnants. We need to evaluate each option based on its geomorphological definition.
Correct Option: D) Peneplain
The question asks to identify the Indian state where wind energy is best harnessed. This requires knowledge of the geographical distribution of wind energy potential and installed capacity in India.
Correct Option: D) Gujarat is one of the leading states in India for wind energy generation, owing to its extensive coastline and high wind speeds, particularly in regions like Kutch and Saurashtra. It has a significant installed capacity and contributes substantially to India's total wind power output.
The question asks for the most suitable practice to prevent land degradation in arid areas. Arid areas are characterized by low rainfall, high temperatures, and often strong winds, leading to desertification and soil erosion. We need to evaluate each option based on its effectiveness in combating these specific challenges.
C) Shelterbelt plantation is the most suitable practice. In arid areas, wind erosion is a major cause of land degradation and desertification. Shelterbelts, which are rows of trees or shrubs planted to protect fields, effectively reduce wind speed, thereby preventing soil particles from being blown away. They also help in moisture retention and can stabilize sand dunes, directly addressing the key challenges of arid environments.
The question asks for the theme of World Water Day on March 22, 2025. To answer this, one needs to be aware of the official themes announced by UN-Water for World Water Day in various years.
Correct Option: D) Glacier preservation
The question asks for a shortcut key combination used in some file management programs to copy a selected item instead of moving it. This implies looking for a less common or program-specific shortcut for copying, as the standard copy shortcut is usually Ctrl + C.
In many older or specific file management programs, especially those that emulate DOS-era file managers (like Norton Commander or its derivatives), the Alt + Ins key combination is used for copying files or directories. This is distinct from the more common Ctrl + C found in modern operating systems like Windows. The question specifically mentions "instead of moving it," which points to a copy operation.
While Ctrl + C is the universal shortcut for copy in Windows, Alt + Ins has historically been used in some contexts, particularly in text editors or file managers where Ins (Insert) was associated with inserting data, and Alt modified its function to copy.
C) Alt + Ins — In some older or specific file management programs, particularly those with a command-line or dual-pane interface, Alt + Ins is indeed used to copy a selected item. This shortcut is less common in modern graphical user interfaces but was prevalent in certain environments.
A) Alt + Del — This combination is not a standard shortcut for copying or moving files. Ctrl + Alt + Del is typically used to open Task Manager or security options in Windows, while Del alone is for deleting.
B) Alt + F4 — This shortcut is universally used to close the currently active window or application in Windows and many other operating systems. It has no function related to copying or moving files.
D) Alt + Tab — This shortcut is used to switch between open applications or windows in Windows and many other operating systems. It is a navigation shortcut and has no function related to file operations like copying or moving.
The question asks about the institution that played a major role in supporting India's liberalisation policy during the 1991 economic crisis. This requires knowledge of the historical context of India's economic reforms and the role of international financial organizations.
Correct Option: D) International Monetary Fund (IMF)
The International Monetary Fund (IMF) played a crucial role in supporting India during the 1991 economic crisis. India approached the IMF for an emergency loan to avert a sovereign default. In exchange for the loan, the IMF imposed conditionalities that required India to undertake significant economic reforms, including liberalisation, deregulation, and opening up its economy to foreign trade and investment. These reforms are collectively known as the Liberalisation, Privatisation, and Globalisation (LPG) policies, which marked a major shift in India's economic trajectory.
The question asks to identify the Act enacted in 2003 to institutionalize fiscal discipline in India during the post-reform era. This requires knowledge of key economic legislations in India and their primary objectives.
The Fiscal Responsibility and Budget Management (FRBM) Act was enacted in 2003. Its primary objective was to institutionalize financial discipline, reduce India's fiscal deficit, and improve macroeconomic management. It set targets for the government to reduce fiscal deficit and revenue deficit, thereby promoting fiscal prudence and long-term macroeconomic stability. This perfectly aligns with the question's description.
The question asks for the main function of an operating system. We need to evaluate each option to determine which one best describes the core role of an OS in a computer system.
Correct Option: C) Managing computer hardware and software resources
This option accurately describes the central and most fundamental function of an operating system. An OS is responsible for allocating CPU time, managing memory, controlling input/output operations, organizing files on storage, and scheduling processes, thereby ensuring that all hardware and software components work together efficiently.
The question asks about the powers exercised by the Union Council of Ministers in India. We need to identify the correct function among the given options by understanding the roles and responsibilities of the executive branch in India's parliamentary system.
D) Framing policies and advising the President
The Union Council of Ministers is the primary body responsible for formulating domestic and foreign policies of the government. Article 74(1) of the Indian Constitution states that there shall be a Council of Ministers with the Prime Minister at the head to aid and advise the President in the exercise of his functions. This advice is binding on the President.
The question asks to identify the third major river system, alongside the Indus and the Ganga, that forms the Northern Plain of India. This requires knowledge of the major geographical features and river systems of India.
Correct Option: A) The Brahmaputra River system, along with the Indus and the Ganga river systems, is responsible for the formation of the Northern Plains of India. The Brahmaputra forms the eastern part of these plains, particularly in Assam.
