Q1.How many of following statements regarding the Tenkasi Iron Age site at Thirumalapuram are correct ?
- The site contains urn burials inside a rectangular stone slab chamber.
- It is the first slab-chamber type urn burial reported in South India.
- The ceramics discovered include black-and-red ware, black-slipped ware, red-slipped ware, and white-painted motifs.
- The site is dated to early to mid-1st millennium BCE.
(a) Only One
(b) Only Two
(c) Only Three
(d) Only Four
Correct Answer: (c)
Explanation: Statements 1,2 ,3 are correct. Statement 4 is incorrect because the site is dated to early to mid-3rd millennium BCE.
Q2. How many of the following factors are natural triggers of landslides in the Himalayan region?
- Heavy rainfall
- Earthquakes
- Steep slopes and unstable geology
- Deforestation
Options:
(a) Only One
(b) Only Two
(c) Only Three
(d) Only Four
Correct Answer: (c)
Explanation: Statements 1,2, 3 are natural causes. Statement 4 is anthropogenic.
Q3. Consider the following statements regarding Natural Farming (NF) in India:
- NF avoids the use of chemical fertilizers and pesticides.
- Practices like Zero Budget Natural Farming (ZBNF) and Induced Natural Farming are variants under NF.
- NF prohibits the use of organic inputs like cow dung, compost, and green manures.
- NF is promoted under the Rashtriya Krishi Vikas Yojana (RKVY).
Options:
(a) 1, 2, and 4 only
(b) 1 and 3 only
(c) 2 and 4 only
(d) All of the above
Correct Answer: (a)
Explanation: NF avoids chemical inputs (1), includes ZBNF and other variants (2), allows organic inputs (so 3 is incorrect), and is promoted via schemes like RKVY (4).
Q4. Second-generation ethanol feedstocks include:
(a) Starch-rich grains
(b) Sugarcane juice
(c) Molasses
(d) Lignocellulosic biomass
Correct Answer: (d)
Explanation: Second-generation ethanol uses non-food lignocellulosic biomass, unlike first-generation ethanol derived from sugarcane or grains.
Q5. Which of the following statements about Quantum Random Number Generation (QRNG) is correct?
(a) QRNG relies on deterministic classical algorithms to generate random numbers
(b) QRNG uses inherently random quantum phenomena like superposition and entanglement
(c) QRNG numbers are always predictable due to device limitations
(d) QRNG cannot be applied for secure encryption
Correct Answer: (b)
Explanation: QRNG derives truly random numbers from quantum phenomena such as superposition and entanglement, unlike classical pseudorandom generators.
