Answer: (b)B.

Four months

Why this answer is correct

The correct answer is Four months.

Key Points

  • Under the Bharatiya Nyaya Sanhita (BNS), 2023, the provisions regarding imprisonment for non-payment of a fine are specified under Section 37.
  • The act mandates that if an offense is punishable with a fine only, any imprisonment imposed due to default in payment must be simple imprisonment.
  • The scale for the term of imprisonment in default is categorized based on the amount of the fine: if the fine does not exceed five thousand rupees, the term cannot exceed two months.
  • For a fine that does not exceed ten thousand rupees, the maximum term of simple imprisonment is fixed at four months.
  • In all other cases, where the fine exceeds ten thousand rupees, the term of imprisonment for default can extend up to a maximum of one year.

 Additional Information

  • Legislative Context:
  • The Bharatiya Nyaya Sanhita, 2023, was enacted to replace the colonial-era Indian Penal Code (IPC) of 1860.
  • The new Sanhita officially came into effect on July 1, 2024, across India.
  • Compared to the IPC (where the limits were fifty and one hundred rupees), the BNS has significantly increased the monetary thresholds for default imprisonment to align with modern economic standards.
  • Section 37 of the BNS corresponds to the old Section 67 of the IPC, but with revised fine slabs and increased maximum jail terms for higher fine amounts.
  • This provision ensures that the duration of imprisonment is proportional to the financial penalty imposed by the court.

Question 145

Delhi Police Head Constable 2025• General Awareness

Read the following and choose the correct option:

Assertion (A): An observer on the ground hears a sonic boom only after a supersonic aircraft has passed over them.

Reason (R): The sonic boom is caused by a conical shock wave formed when the aircraft travels faster than the speed of sound, and this shock wave continuously trails behind the aircraft as it moves.

  1. AOption (a)

    Both A and R are true and R is the correct explanation of A.

  2. BOption (b)

    Both A and R are true but R is not the correct explanation of A.

  3. COption (c)

    A is true but R is false.

  4. DOption (d)

    A is false but R is true.

View answer & explanation

Correct answer

Answer: (a)A.

Both A and R are true and R is the correct explanation of A.

Why this answer is correct

The correct answer is Both A and R are true and R is the correct explanation of A.

Key Points

Assertion (A) is based on the physics of supersonic flight. When an aircraft travels faster than the speed of sound, it moves ahead of the sound waves it produces. Consequently, the aircraft passes over an observer before the sound waves (the sonic boom) ever reach them. Hence, statement A is correct. Reason (R) explains the mechanism of the sonic boom. As a supersonic aircraft cuts through the air, it creates a series of pressure waves that coalesce into a single conical shock wave, often called a Mach cone. This shock wave is a continuous surface of high pressure that trails behind the aircraft like a wake behind a boat. Hence, statement R is correct. The sonic boom is the sudden, explosive noise heard when the surface of this trailing Mach cone finally reaches the observer's ears. Since the aircraft is at the vertex of the cone and the cone surface angles backward, the aircraft must logically pass a point on the ground before the trailing shock wave intersects that same point. Therefore, the trailing nature of the shock wave directly explains the observed delay. Hence, R is the correct explanation of A.

 Additional Information

Mach Number (M):

It is the ratio of the speed of the object to the speed of sound in the surrounding medium. If M > 1, the object is supersonic; if M > 5, it is considered hypersonic.

Shock Wave Characteristics:

A shock wave involves an almost instantaneous increase in pressure, temperature, and density. The Mach Angle (the half-angle of the cone) is calculated using the formula sin(theta) = 1/M. As the aircraft speed increases, the cone becomes narrower. A typical sonic boom profile is known as an N-wave because the pressure rises sharply at the nose (bow shock), decreases linearly, and then rises sharply again at the tail (tail shock).

Question 146

Delhi Police Head Constable 2025• General Awareness

  1. AOption (a)

    Air Quality Index

  2. BOption (b)

    Annual Quota Indicator

  3. COption (c)

    Average Quotient of Industry

  4. DOption (d)

    Air Quota Initiative

View answer & explanation

Correct answer

Answer: (a)A.

Air Quality Index

Why this answer is correct

The correct answer is Air Quality Index.

Key Points

  • The Air Quality Index (AQI) was launched in India in September 2014 as part of the Swachh Bharat Abhiyan to provide a simplified 'One Number-One Colour-One Description' format for the general public to judge air quality.
  • It is a vital tool for environmental monitoring that transforms complex air quality data of various pollutants into a single numerical value representing the level of atmospheric pollution.
  • The National Air Quality Index considers eight major pollutants to determine the air quality: Particulate Matter (PM10), Particulate Matter (PM2.5), Nitrogen Dioxide (NO2), Sulphur Dioxide (SO2), Carbon Monoxide (CO), Ozone (O3), Ammonia (NH3), and Lead (Pb).
  • The index is calculated based on the National Ambient Air Quality Standards (NAAQS), where a sub-index is calculated for each pollutant, and the highest sub-index value is designated as the overall AQI for that specific location and time.

 Additional Information

  • AQI Categories and Health Impacts:
  • Good (0-50): Minimal impact on human health.
  • Satisfactory (51-100): May cause minor breathing discomfort to sensitive people.
  • Moderately Polluted (101-200): Likely to cause breathing discomfort to people with lung diseases like asthma and discomfort to children and elderly.
  • Poor (201-300): Can lead to breathing discomfort on prolonged exposure and heart diseases.
  • Very Poor (301-400): May cause respiratory illness on prolonged exposure; effect may be more pronounced in people with lung and heart diseases.
  • Severe (401-500): Affects healthy people and seriously impacts those with existing respiratory or cardiovascular diseases.
  • Regulatory Bodies:
  • The Central Pollution Control Board (CPCB), in consultation with IIT Kanpur and other experts, developed the methodology for the Indian AQI.
  • The Ministry of Environment, Forest and Climate Change (MoEFCC) oversees the implementation of air quality standards across India.

View answer & explanation

Correct answer

Answer: (c)C.

World Bank and International Monetary Fund (IMF)

Why this answer is correct

The correct answer is World Bank and International Monetary Fund (IMF).

Key Points

  • In 1991, India faced a severe Balance of Payments (BoP) crisis, where its foreign exchange reserves dwindled to approximately $1.2 billion, barely enough to sustain two weeks of essential imports like petroleum.
  • To address this emergency, the Indian government, under Prime Minister P.V. Narasimha Rao and Finance Minister Dr. Manmohan Singh, approached the International Bank for Reconstruction and Development (IBRD), commonly known as the World Bank, and the International Monetary Fund (IMF).
  • India secured a bailout loan of $7 billion from these international financial institutions to manage its immediate debt obligations and stabilize the economy.
  • The loan was granted on the condition that India would implement structural reforms to move from a command economy to a more market-oriented economy, involving the removal of trade barriers and reducing government control.
  • These conditionalities directly led to the announcement of the New Economic Policy (NEP) in July 1991, which introduced the LPG (Liberalisation, Privatisation, and Globalisation) framework to the Indian economic landscape.

 Additional Information

  • International Monetary Fund (IMF)
  • Established in 1944 at the Bretton Woods Conference, it is headquartered in Washington, D.C.
  • Its primary mission is to ensure the stability of the international monetary system and provide short-to-medium-term loans to countries facing BoP crises.
  • World Bank (IBRD)
  • Formed alongside the IMF in 1944, it focuses on long-term economic development and poverty reduction through infrastructure and human capital projects.
  • Other Organizations Mentioned
  • Asian Development Bank (ADB): Founded in 1966, it focuses on development in Asia but was not the primary architect of the 1991 structural reforms.
  • World Trade Organization (WTO): This organization was established in 1995, replacing the General Agreement on Tariffs and Trade (GATT), and thus did not exist during the 1991 crisis.
  • European Union (EU): A regional political and economic union of 27 member states located primarily in Europe, focusing on regional integration.
