Question Discussion & Solution

The correct answer is Afforestation.

• Afforestation is not a cause of soil erosion.

Key Points

• Afforestation is planting trees on an area of land in order to form a forest.
• Removal of the top layer of soil when it is exposed to wind and rain is easily blown or washed away. This condition is known as soil erosion.
  • Basically, the soil cover is removed by two powerful agents– (i) Running water, (ii) Wind.
• Deforestation, overgrazing, floods, Landslides and heavy rainfall have led to soil erosion.

Similarly,

From the above we can get

Hence, READ is written as “#%4$”

 CONCEPT:

• Electromagnetic waves or EM waves (Lightwave): The waves that are formed as a result of vibrations between an electric field and a magnetic field and they are perpendicular to each other and to the direction of the wave is called an electromagnetic wave.
• The accelerating charged particle produces an electromagnetic (EM) wave.
• A charged particle oscillating about an equilibrium position is an accelerating charged particle.
• Electromagnetic waves do not require any matter to propagate from one place to another as it consists of photons.
• Hence they can move in a vacuum 

Properties of Lightwaves:

• Not have any charge or we can say that they are neutral.
• Propagate as a transverse wave with both wave and particle nature.
• They move with the velocity the same as that of light i.e 3 × 108 m/s.
• It contains energy and they also contain momentum.
• They can travel in a vacuum also and always travel in a straight line.

EXPLANATION:

• All of the above-given statements are true.
• Light travels in a straight line until its path is obstructed.
• Light has dual nature, that is, it shows both waves as well as particle nature.
• Light is a transverse wave as the particles of lightwave vibrate in a direction perpendicular to the direction of propagation.

The correct answer is Viceroy Curzon.

Key Points

• Lord Curzon:
  • ​He served as Governor-General of India from 1899 to 1905.
  • He passed the Calcutta Corporation Act in the year 1899.
  • According to the act, it increased the number of official members and decreased the strength of elected official members.
  • As official members were mostly British Subjects it caused resentment in the Indian public.
  • He was the Viceroy who passed a law for protecting Ancient Indian monuments.
  • He passed the law in 1904 made the destruction of Ancient Monuments an offence and directed officials to collect and preserve ancient monuments.
  • British viceroy in India, Lord Curzon, carried out Partition of Bengal, (1905) despite strong Indian nationalist opposition.

Additional Information

• The Partition of Bengal was announced on 19 July 1905 by the then Viceroy Lord Curzon.
  • And was implemented on 16 October 1905
  • However, in 1911 it was withdrawn by Lord Hardinge.
• The stated reason was to ease the administration.
  • But the actual reason was to weaken the growing nationalism in Bengal and break the unity.
• As per Curzon, after the partition, the two provinces would be Bengal (including modern West Bengal, Odisha, and Bihar) and Eastern Bengal and Assam.
• Annulment of Bengal:
  • The partition of Bengal was annulled in 1911 by Lord Hardinge.
  • The capital of British India was moved to Delhi from Calcutta in 1911.
  • Despite the annulment, the partition already succeeded in making a communal divide between Muslims and Hindus of Bengal.

The correct answer is Kuchipudi Dance.

• Yamini Krishnamurti is related to Kuchipudi Dance.

Key Points 

• Yamini Krishnamurti is a Kuchipudi dancer.
• She also knows Bharatnatyam.
• A Passion For Dance is her autobiography.
• Kuchipudi:
  • It is the classical dance of Andhra Pradesh.
  • Kuchipudi derives its name from the Kuchipudi village of Andhra Pradesh.
  • Kuchipudi exhibits scenes from the Hindu Epics, legends and mythological tales through a combination of music, dance and acting.
  • Like other classical dances, Kuchipudi also comprises pure dance, mime and histrionics but it is the use of speech that distinguishes Kuchipudi’s presentation as dance-drama.
  • ‘At times, even though the dramatic situation did not demand, solo dancing was being presented to punctuate the presentation and to enhance the appeal. One such number is tarangam inspired by the Krishna-Leela tarangini of Teerthanarayana Yogi.
  • There are now two forms of Kuchipudi
    • The traditional musical dance drama 
    • The solo dance.
• Bharatnatyam is the classical dance of Tamil Nadu.
