P.T. Practice Questions 15th April 2021

Q. 1 Consider the following statements about The Hydrogen Economy – New Delhi Dialogue 2021:

  1. It is organised by The Energy Forum (TEF) and the Federation of Indian Petroleum Industry (FIPI), under the aegis of Ministry of Petroleum and Natural Gas, Government of India.
  2. Hydrogen is gaining increasing importance as a source to bridge energy gaps as it cannot be used as a standalone source to conventional fuels.

Choose the correct option:

  1. 1 only
  2. 2 only
  3. Both 1 and 2
  4. Neither 1 nor 2

Ans: a (1 Only)

Explanation

The Energy Forum (TEF) and the Federation of Indian Petroleum Industry (FIPI), under the aegis of Ministry of Petroleum and Natural Gas, Government of India, are organising a Hydrogen Roundtable titled “Hydrogen Economy- the Indian Dialogue-2021” in a virtual mode on 15th April, 2021 to discuss emerging hydrogen ecosystems and exploring opportunities for collaboration, cooperation and coalition.

As the world chases its international climate commitments and takes steps to counter climate change, Hydrogen is gaining increasing importance as a source to bridge energy gaps and also as a standalone source to conventional fuels.

The Hydrogen Roundtable, the first of its kind, will comprise a High-level Ministerial Session, followed by five Panel Discussions by eminent policy makers, experts and industry leaders from different geographical regions of the world, with focus on policy roadmaps and mapping demand and supply of Hydrogen.

Q. 2 Consider the following statements about the hydrogen sulphide (H2S):

  1. It is a poisonous, corrosive, and flammable gas produced from swamps and sewers.
  2. H2S is the primary gas produced from the microbial breakdown of organic matter in the absence of oxygen.

Choose the correct option:

  1. 1 only
  2. 2 only
  3. Both 1 and 2
  4. Neither 1 nor 2

Ans: c (Both 1 and 2)

Explanation

Scientists have developed an electronic nose with biodegradable polymer and monomer that can detect hydrogen sulphide (H2S), a poisonous, corrosive, and flammable gas produced from swamps and sewers.

H2S is the primary gas produced from the microbial breakdown of organic matter in the absence of oxygen, and this necessitates easy detection of its emission from sewers and swamps.

Responding to this challenge, scientists from the Centre for Nano and Soft Matter Sciences (CeNS), Bangalore, an autonomous institute of the Department of Science & Technology, Government of India, in collaboration with their counterparts from Saudi Arabia, have developed an exceptionally sensitive and selective H2S Gas sensor developed by impersonating the neuron responsible for identification of airborne molecules or olfactory receptor neuron (ORN).

Q. 3 Consider the following statements about Dayanand Saraswati:

  1. He started Arya samaj.
  2. He believed in infallibility of Vedas.
  3. He was opposed to idolatry, ritual and priesthood.
  4. He was against performing Yajana.

Which of the statement is/are correct:

  1. 1, 2 and 3 Only
  2. 1, 3 and 4 Only
  3. 1, 2 and 4 Only
  4. All of the above

Ans: a ( 1, 2 and 3)

Explanation

Statement 1 is correct as Dayanand Saraswati founded Arya samaj in 1875.

Statement 2 is correct as the most influential movement of religious and social reform in northern India was started by Dayanand Saraswati. He held that the Vedas contained all the knowledge imparted to man by God and essentials of modern science could also be traced in them.

Statement 3 is correct as he was opposed to idolatry, ritual and priesthood, particularly to the prevalent caste practices and popular Hinduism as preached by the Brahmins. He favoured the study of western science. 

Statement 4 is incorrect as he favoured performing yajnas and reading religious scriptures.

Q. 4 In what ways is/are Hindustani Music style different from that to Carnatic Music?

  1. Hindustani classical music is most prevalent in North India, while Carnatic music is prevalent in South India.
  2. Sarangi is a major instrument used in Hindustani style, while violin is a major instrument used in Carnatic.

Select the correct answer using the options given below:

(a)   1 Only

(b)   2 Only

(c)   Both 1 and 2

(d)   Neither 1 nor 2

Ans- c (Both 1 and 2)

Explanation:

The Indian music system is divided into Hindustani and Carnatic. The key differences between the Hindustani and Carnatic systems are:

●  The origin of Hindustani Music can be considered from the Delhi Sultanate and Amir Khusrow. It is predominant in north India.

●  Dhrupad is considered as the oldest creation of Hindustani music, which is a creation of Swami Haridas. Over the time Khyal, Thumri, Thappa Tirana etc. developed as the distinct styles of Hindustani music.

●  Purandar Das is considered as the founder of the Carnatic style of music. The credit for the development of the Carnatic style goes mainly to three musicians named— Shyama Shastri, Tyagaraja and Muthuswami Dikshitar. This style is predominant in south India. Hence, statement 1 is correct.

●  The sarangi is a major accompaniment in Hindustani music, while the violin reigns in Carnatic. Hence, statement 2 is correct.
