DAY 17 (03-10-23)
Q1. Consider the following statements :
- The Chromosphere is a layer in the Sun between about 400 km and 2100 km above the solar surface (the photosphere).
- The Convection Zoneis the deepest layer of the Sun that we can observe directly.
- The radiative zone is the second inner layer of the Sun.
Which of the statements given above are correct?
(a) 1 and 2 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3
Answer: (c)
Explanation:
Statement 1 is correct: The chromosphere is a layer in the Sun between about 400 km and 2100 km above the solar surface (the photosphere).The temperature in the chromosphere varies between about 4000 K at the bottom (the so-called temperature minimum) and 8000 K at the top.
Statement 2 is incorrect:The photosphere is the deepest layer of the Sun that we can observe directly. In Convection Zoneall of the hot material found near the center of the Sun rises cools down and drops back into the radiative zone to get more heat.This is the movement that creates sunspots and solar flares. This layer marks the border of what we usually refer to as the Sun.
Statement 3 is correct:The radiative zone is the second inner layer of the Sun. It sits outside of the core, and it holds its extremely high temperature. The zone itself has a temperature of around 7 million degrees Fahrenheit. This layer serves as a passage for all the energy that is released by the core. Photons travel through the radiative zone, and they can’t travel through long ranges of space, so it takes almost 50 million years for a photon to travel through this layer of the Sun.
Q2. Consider the following statements regarding National Commission for Scheduled Castes :
- It is a constitutional body under Article 338A.
- It investigates and monitor all matters relating to the constitutional and other legal safeguards for the Scheduled Castes.
- Its recommendations are binding on Government.
How many of the above statements are correct?
(a) Only one
(b) Only two
(c) All three
(d) None
Answer: (a)
Explanation:
Statement 1 is incorrect: National Commission for Scheduled Castes (NCSC) is a constitutional body that works to safeguard the interests of the scheduled castes (SC) in India. Article 338 of the constitution of India deals with this commission.
Statement 2 is correct: NCSC investigates and monitor all matters relating to the constitutional and other legal safeguards for the SCs and to evaluate their working.
Statement 3 is incorrect: NCSC recommendations are binding on Government and it has no role in criminal cases.
Q3. With reference to the cultural history of India, the memorizing of chronicles, dynastic histories and epic tales was the profession of who of the following?
(a) Shramana
(b) Parivraajaka
(c) Agrahaarika
(d) Maagadha
Answer: (d)
Explanation:
- Maagadha were the people who were related to priestly families of the Vedic age. Their main job was to memorize and narrate the chronicles, dynastic histories or war stories of rulers or warriors.
- Every king’s court had one Maagadha who was conversant with his royal master’s dynastic account and deeds. Maagadhas were what we know as “chroniclers” today. The Sutas used to gather from these Maagadhas the local itivritta or ‘history’. Should any Maagadha exaggerate anything about his master or hide some fault of his, the Suta would rectify that. It is because of this that the Sutas were known as satyavrataparayana. The Sutas knew the dynastic accounts of all kings.
Q4. Consider the following statements
- The Major Port Authorities Act 2021vests the administration, control and management of such ports upon the Boards of Major Port Authorities.
- The Sagarmala projects include coastal community development.
Which of the statements given above are correct?
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Answer: (c)
Explanation:
Statement 1 is correct: The Major Port Authorities Act 2021 act provides for inter alia regulation, operation and planning of major ports in India and vests the administration, control and management of such ports upon the Boards of Major Port Authorities.
Statement 2 is correct:Sagarmala which is a National Programme aimed at accelerating economic development in the country by harnessing the potential of India’s 7,500 km long coastline and 14,500 km of potentially navigable waterways. The Sagarmala projects include port modernization & new port development, connectivity enhancement, port-led industrialization, coastal community development, coastal shipping and Inland water transport.
Q5. “Growth With Social Justice & Equality” was the aim which five year plan?
(a) Fourth
(b) Sixth
(c) Ninth
(d) Eleventh
