Q42. With reference to India’s satellite launch vehicles, consider the following statements: 1. PSLVs launch the satellite useful for Earth resources monitoring whereas GSLVs are designed mainly to launch communication satellites. 2. Satellites launched by PSLV appear to remain permanently fixed in the same position in the sky, as viewed from a particular location on Earth. 3. GSLV Mk III is a four staged launch vehicle with the first and third stages using solid rocket motors; and the second and fourth stages using liquid rocket engines. Which of the statements given above is/are correct?
Explanation
Statement 1 is correct: The Polar Satellite Launch Vehicle (PSLV) is primarily used to place satellites in Sun-Synchronous Polar Orbits (SSO), which are ideal for Earth observation, remote sensing, and resource monitoring. The Geosynchronous Satellite Launch Vehicle (GSLV) is used to place communication satellites into Geostationary Transfer Orbit (GTO), from where they move into Geostationary Orbit (GEO) for telecom and broadcasting services.
Statement 2 is incorrect:
Geostationary satellites (which remain fixed over a location) are launched into Geostationary Orbit (GEO) at 35,786 km altitude, usually by GSLV, not PSLV. PSLV typically places satellites in Low Earth Orbit (LEO) or Sun-Synchronous Orbit (SSO), where they move relative to the Earth’s surface.
Statement 3 is incorrect:
GSLV Mk III (now LVM3) is actually a three-stage launch vehicle:
First stage: Two solid rocket boosters (S200) Second stage: A liquid-fueled core stage (L110) Third stage: A cryogenic stage (C25) There is no fourth stage in GSLV Mk III, making the statement incorrect.
Exam tip:
For S2, PSLV places satellites in polar orbits also and not necessarily in geostationary. Hence S2 is overly restrictive and likely false. For S3, When UPSC gives too much technical detail, its easier to manipulate and make it false.

Union Ministry of Environment, Forest and Climate Change officially decides and declares Habitat Rights for Primitive and Vulnerable Tribal Groups in any part of India. Which of the statements given above is/are correct?
Explanation
Statement 1 is correct: Critical Wildlife Habitats (CWH) are defined under the Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act, 2006.. These are areas within wildlife sanctuaries and national parks that are critical for the survival of wildlife species and where human activities may be restricted.
Statement 2 is correct: The Baiga tribe in Madhya Pradesh was one of the first communities in India to be granted Habitat Rights under the Forest Rights Act, 2006. This recognition ensures their right to live in and sustainably use forest resources in their traditional habitats.
Statement 3 is incorrect: The declaration of Habitat Rights is the responsibility of the Ministry of Tribal Affairs and state-level authorities under the framework of the Forest Rights Act, 2006.
Exam tip:
For S3, aligns with Function-person/organisation/ministry match trap as its easy to manipulate to make it false. Isn’t it should be Tribal affairs ministry??

Q44. With reference to the election of the President of India, consider the following statements: 1. The value of the vote of each MLA varies from State to State. 2. The value of the vote of MPs of the Lok Sabha is more than the value of the vote of MPs of the Rajya Sabha. Which of the statements given above is/are correct?
Explanation
The President of India is elected indirectly by the Electoral College and it is conducted in accordance with the system of proportional representation by means of single transferable vote.

1. Elected members of the two Houses of Parliament and Legislative Assemblies of the States

Statement 2 is incorrect: The value of vote of each MP is the same whether it is Lok Sabha or Rajya Sabha. There shall be uniformity in the scale of representation of the different states at the election of the President as follows:
Value of vote of an MLA of a state:
(Population of state / Total number of elected members of state legislative assembly) * 100 Value of vote of an MP: (Total value of votes of MLA’s of all states/ Total number of elected members parliament) * 100

Q45. Consider the following statements: 1. In India, State Governments do not have the power to auction non-coal mines. 2. Andhra Pradesh and Jharkhand do not have gold mines. 3. Rajasthan has iron ore mines. Which of the statements given above is/are correct?
Explanation
Statement 1 is incorrect: According to the Mines and Minerals (Development and Regulation) Amendment Act, 2015 (MMDR Amendment Act), state governments have the power to auction non-coal mines. The central government sets the guidelines for the auction process, but the actual auction of non-coal mines is conducted by the state governments.
Statement 2 is incorrect: Andhra Pradesh and Jharkhand do have gold mines. Andhra Pradesh: Gold is found in Ramagiri in the Anantapur district. Jharkhand: Both alluvial and native gold are present, with alluvial gold found in the sands of the Subarnarekha River and Sona Nadi, and native gold found near Lowa in the Singhbhum district. Largest gold ore deposits in India are found in Bihar (based on recent discovery but not certified yet by GSI), Rajasthan, and Karnataka with Andhra Pradesh and Jharkhand having smaller reserves.
Statement 3 is correct: Rajasthan has significant iron ore deposits. Iron ore deposits, primarily hematite and magnetite, are found in Rajasthan, specifically in districts like Jaipur, Udaipur, Jhunjhunu, Sikar, Bhilwara, Alwar, Bharatpur, Dausa, and Banswara. These deposits contribute to the production of iron in India.
Exam tip:
For S1, Mining is a State subject, so logically, States should have control over mineral auctions except where central laws specify otherwise. And Non-coal minerals is a big basket including minor minerals, it would be absurd to keep state governments out it, hence likely false.
