3. Only Scheduled Tribe students can be enrolled into these schools.

Answer: D
Soln:
Eklavya Model Residential School (EMRS):
● The Ministry of Tribal Affairs is implementing the Central Sector Scheme of Eklavya
Model Residential School (EMRS) to provide quality middle and high-level education to
Scheduled Tribe (ST) students in remote areas. Hence, statement 1 is incorrect.
● Introduced in 1997-98, the schools are aimed to enable ST students to access the best
opportunities in education and to bring them at par with the general population.

organization under the Ministry of Tribal Affairs, establishes, endows, maintains, controls
and manages these schools. Hence, statement 2 is incorrect.
● The government aims to establish EMRS in every block with more than 50% ST
population and at least 20,000 tribal persons.
● EMRS are set up in States/UTs with grants under Article 275(1) of the Constitution of

2. Oxytocin, a natural hormone, is involved in which of the following processes within the human
body?

Answer: B
Soln:
● Oxytocin is a natural hormone that stimulates uterine contractions in childbirth and
lactation after childbirth. It also affects aspects of human behavior and the male and

○ Hormones are chemicals that coordinate different functions in our body by
carrying messages through blood to the organs, muscles and other tissues. These
signals tell our body what to do and when to do it

● It is secreted by the hypothalamus but stored and released into our bloodstream by
the posterior pituitary gland.

3. Consider the following statements about External Debts.
1. External debt is the portion of a country's debt that is borrowed from foreign lenders.
2. India has an external debt to GDP ratio of over 50 percent.

Answer: A
Soln:
External Debt
● External debt is the portion of a country's debt that is borrowed from foreign lenders
through commercial banks, governments, or international financial institutions. Hence,
statement 1 is correct.
● India’s external debt includes Commercial Borrowings, Sovereign Borrowings, Non-
Resident Deposits, Multilateral Loans and Trade credits.
● According to data released by the Reserve Bank of India (RBI), India’s external debt at
end-March 2024 was at $ 663.8 billion, recording an increase of $ 39.7 billion over its level
at end-March 2023.
● The external debt to GDP ratio declined to 18.7 per cent at end-March 2024 from 19.0
per cent at end-March 2023. Hence, statement 2 is incorrect.
● The Central Bank said that if the valuation effect were excluded, external debt would have

4. Consider the following statements about Super-Absorbent Polymers (SAP).
1. It is a type of macro molecular synthetic water absorbing polymer material.
2. SAPs are always of synthetic origin.

Answer: A
Soln:
Super-Absorbent Polymers:

● Super Absorbent Polymers (SAP) is a type of macro molecular synthetic water absorbing
polymer material. Hence, statement 1 is correct.
● It is a whitish powder.
● SAP can absorb a large amount of water, at times more than its own weight.
● According to their source of origin, SAPs can be classified as natural (polysaccharide and
polypeptide based) and synthetic polymers (chemical based). Hence, statement 2 is
incorrect.
● The molecular structure of this compound resembles the complicated mesh.
● When it comes in contact with water the oxygen atoms of water are attracted to the mesh
due to the presence of Sodium ions in SAP.
● As the water molecules attach themselves to the sodium ions in the SAP a strong network
is formed. The whole network swells, trapping the water molecules within, to form a
gel.
Applications
● Due to its superabsorbent nature, it is ideally suited for personal hygiene and
incontinence applications as diapers and pads.
● They can be used to improve and prolong soil water holding capacity, decrease drought
stress, and increase time between irrigation events.
