Why this answer is correct

The correct answer to the question regarding 'Alcatraz' is 3) 1, 2 and 3.

Key Points

Statement 1: It was once a defence fort on Alcatraz island of America.

  • Status: Correct.
  • Reason: In 1850, a presidential order set aside Alcatraz Island for military use. By 1859, the Fort Alcatraz was completed, becoming the most heavily fortified military site on the West Coast to protect San Francisco Bay during the Gold Rush and the Civil War. It featured over 100 cannons and served as a primary "triangle of defense" for the bay.

Statement 2: It was once a prison on Alcatraz island of America.

  • Status: Correct.
  • Reason: Alcatraz is most famous for its role as a prison. It transitioned from a military prison (starting as early as 1859-1861) to a notorious federal penitentiary in 1934. Known as "The Rock," it held famous criminals like Al Capone until it was closed in 1963 due to high operating costs.

Statement 3: It was once occupied by a group of native American students, known as 'Indians of all tribes'.

  • Status: Correct.
  • Reason: From November 20, 1969, to June 11, 1971, a group of Native American activists and students—calling themselves the Indians of All Tribes (IAT)—occupied the island. Led by figures like Richard Oakes and LaNada Means, they claimed the land based on the 1868 Treaty of Fort Laramie, which stated that retired or out-of-use federal land should return to Indigenous people.

  • Status: Correct.
  • Reason: The HAMMER (Highly Agile Modular Munition Extended Range) is a French-made stand-off weapon system designed by Safran Electronics & Defense specifically for the Rafale fighter jets. The Indian Air Force (IAF) integrated these precision-guided munitions into its Rafale fleet to enhance its air-to-ground strike capabilities.

Statement 2: SCALP cruise missile is also known as Storm Shadow.

  • Status: Correct.
  • Reason: These are the same long-range, air-launched cruise missiles developed by MBDA. Storm Shadow is the name used by the British Royal Air Force, while SCALP EG (Système de Croisière Autonome à Longue Portée – Emploi Général) is the name used in France. India received the SCALP version along with its Rafale fighters.

Statement 3: BrahMos missiles are built under a joint venture between India and Russia.

  • Status: Correct.
  • Reason: The BrahMos is a supersonic cruise missile produced by BrahMos Aerospace, a joint venture established in 1998 between India's DRDO (Defence Research and Development Organisation) and Russia's NPO Mashinostroyeniya. The name is a combination of the Brahmaputra and Moskva rivers.

Question 317

  1. AOption (a)

    1 only

  2. BOption (b)

    2 only

  3. COption (c)

    Both 1 and 2

  4. DOption (d)

    Neither 1 nor 2

View answer & explanation

Correct answer

Answer: (b)B.

2 only

Why this answer is correct

The correct answer is 2 only.

Key PointsStatement 1: Incorrect

While both are indeed the worl d's first genome-edited rice varieties, they were developed by two different institutes under ICAR, not just IARI New Delhi.

  • Pusa DST Rice 1: Developed by the ICAR-Indian Agricultural Research Institute (IARI), New Delhi. This variety is designed to be drought-tolerant and salt-tolerant.
  • DRR Rice 100 (Kamla): Developed by the ICAR-Indian Institute of Rice Research (IIRR), Hyderabad (formerly known as the Directorate of Rice Research - DRR).

Because the statement claims both were developed by IARI, it is factually incorrect.

Statement 2: Correct

This statement accurately describes the characteristics of the "Kamla" variety:

  • Base Variety: It is an improved version of the popular Samba Mahsuri rice.
  • Trait: It has been genome-edited to have a shorter duration of maturity.
  • Benefit: Standard Samba Mahsuri takes about 135–140 days to mature. The edited DRR Rice 100 matures in about 110–115 days, saving farmers nearly a month of water and labor while maintaining the premium grain quality.

Why is this a "First"?

These varieties were developed using CRISPR/Cas9 genome-editing technology.

In 2022, the Government of India exempted SDN-1 and SDN-2 categories of genome-edited plants from the stringent Biosafety regulations (GEAC) that govern Genetically Modified (GM) crops. This is because genome editing (like in these rice varieties) does not involve introducing foreign DNA, but rather "tweaks" the plant's own existing DNA to express better traits.

Note for Exam Prep: Always double-check the location of ICAR institutes.

  • IARI: New Delhi (The "Pusa" varieties)
  • IIRR: Hyderabad (The "DRR" varieties)

Question 318

Combined Defence Services (CDS) 2025• General Knowledge

Which one of the following is a good statistic to evaluate where an economy stands in the financial cycle?

  1. AOption (a)

    Tax/GDP Ratio

  2. BOption (b)

    Fiscal Deficit/GDP Ratio

  3. COption (c)

    Household Consumption/GDP Ratio

  4. DOption (d)

    Credit/GDP Ratio

View answer & explanation

Correct answer

Answer: (d)D.

Credit/GDP Ratio

Why this answer is correct

The correct answer to the question in the image is 4) Credit/GDP Ratio.

Key Points

The financial cycle refers to the self-reinforcing interactions between perceptions of value and risk, and the subsequent expansion or contraction of credit. The Credit/GDP ratio is considered the "gold standard" for this evaluation for several reasons:

  • Captures Systemic Risk: It measures the total amount of credit (debt) extended to the private non-financial sector relative to the size of the economy. A rapidly rising ratio often signals the buildup of systemic risk and potential asset bubbles.
  • Identifies "Financial Deepening": It helps distinguish between healthy financial growth and "excessive" credit that could lead to a banking crisis.
  • Basel III Requirement: International banking regulations (Basel III) specifically use the Credit-to-GDP Gap (the deviation of the current ratio from its long-term trend) to determine when banks should build up "Countercyclical Capital Buffers" to protect against future crashes.

Why the Other Options are Incorrect?

 

  • 1) Tax/GDP Ratio: This measures the size of a government's tax revenue relative to its economy. It is a tool for fiscal policy analysis, not financial cycle monitoring.
  • 2) Fiscal Deficit/GDP Ratio: This indicates the health of government finances and how much the state is borrowing to fund its spending.
  • 3) Household Consumption/GDP Ratio: This is a component of the business cycle, showing how much of the economy's output is driven by private spending.

View answer & explanation

Correct answer

Answer: (a)A.

1 only

Why this answer is correct

The correct answer to the question is 1) 1 only.

Key Points

Statement 1: Correct:

Global Capability Centres (GCCs): Reshaping corporate landscape

  • What they are: GCCs are offshore units of multinational corporations (MNCs) that perform high-end functions like R&D, IT support, and business process management.
  • Impact on India: India has become a global hub for GCCs. They have evolved from simple back-office operations into sophisticated "innovation centers." They are reshaping the corporate landscape by driving digital transformation, creating high-skill jobs, and contributing significantly to the service export economy.
  • Economic Significance: They play a major role in moving India up the value chain in the global services sector.

Statement 2: Incorrect

U-WIN Portal : Ease of doing business across states

  • The Error: The U-WIN portal is not related to "Ease of Doing Business."
  • Actual Objective: The U-WIN (Universal Immunization Programme) portal is designed to digitize India's immunization services. It is modeled after the successful Co-WIN platform used for COVID-19 vaccinations.
  • Function: It is used to register every pregnant woman and child, record birth doses and subsequent vaccinations, and provide digital immunization certificates. Its goal is to create a single source of truth for immunization status across the country.

Question 320

  1. AOption (a)

    Deen Dayal Antyodaya Yojana

  2. BOption (b)

    National Urban Digital Mission

  3. COption (c)

    Atal Mission for Rejuvenation and Urban Transformation

  4. DOption (d)

    Rashtriya Gram Swaraj Abhiyan

View answer & explanation

Correct answer

Answer: (a)A.

Deen Dayal Antyodaya Yojana

Why this answer is correct

The correct answer is Option 1: Deen Dayal Antyodaya Yojana.

Key Points

The Deen Dayal Antyodaya Yojana (DAY) was launched by the Government of India to uplift the urban and rural poor through skill development and sustainable livelihood opportunities. The urban component, known as NULM, is implemented by the Ministry of Housing and Urban Affairs.

1. What is Social Mobilisation and Institution Development (SM&ID)?

SM&ID is considered the "building block" of the mission. Its primary goal is to organize the urban poor into community-based institutions to help them become self-reliant.

  • Self-Help Groups (SHGs): The mission starts by mobilizing the poor into SHGs at the grassroots level.
  • Federations: These SHGs are then federated into Area Level Federations (ALFs) and City Level Federations (CLFs) to give them a stronger collective voice and better bargaining power.
  • Financial Inclusion: Through these institutions, members gain access to revolving funds and credit from banks.

2. Other Key Components of DAY-NULM

To provide a complete picture for your exam preparation, here are the other major components of this mission:

  • Employment through Skills Training and Placement (EST&P): Providing market-oriented skills to the urban poor.
  • Self-Employment Programme (SEP): Providing subsidized loans to individuals or groups to set up micro-enterprises.
  • Support to Urban Street Vendors (SUSV): Helping vendors access credit, social security, and designated vending zones.
  • Scheme for Shelter for Urban Homeless (SUH): Building and managing shelters with essential services for the homeless.

Why the other options are incorrect:

  • National Urban Digital Mission (NUDM): Launched to create a shared digital infrastructure for Indian cities (like citizen portals and data exchange), not social mobilization.
  • Atal Mission for Rejuvenation and Urban Transformation (AMRUT): Focuses on infrastructure—providing basic services like water supply, sewerage, and urban transport to households.
  • Rashtriya Gram Swaraj Abhiyan (RGSA): This scheme is focused on strengthening Panchayati Raj Institutions (PRIs) in rural areas to help them achieve Sustainable Development Goals.
