1. POLYCRACK is world’s first patented heterogeneous catalytic process, which converts multiple feed-stock into hydrocarbon liquid fuels, gas, carbon and water.
2. Polycrack Plant can be fed with all types of wastes provided they are segregated.
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Ans: a
Justification:
- POLYCRACK is world’s first patented heterogeneous catalytic process, which converts multiple feedstock into hydrocarbon liquid fuels, gas, carbon and water.
- Polycrack Plant can be fed with all types of Plastic, Petroleum sludge, Un-segregated MSW (Municipal Solid Waste) with moisture up to 50%, E–Waste, Automobile fluff, Organic waste including bamboo, garden waste etc., and Jatropha fruit and palm bunch.
- The process is a closed loop system and does not emit any hazardous pollutants into the atmosphere.

(a) Odisha
(b) Tamil Nadu
(c) Rajasthan
(d) Himachal Pradesh

3. Which of the following statements are true?
1. Bio rock is the name given to the substance formed by electro accumulation of minerals dissolved in seawater on steel structures that are lowered onto the sea bed.
2. The technology works by passing a small amount of electrical current through electrodes in the water.
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Ans: c
Justification:
- Bio rock is the name given to the substance formed by electro accumulation of minerals dissolved in seawater on steel structures that are lowered onto the sea bed.
- The technology works by passing a small amount of electrical current through electrodes in the water.
- When a positively charged anode and negatively charged cathode are placed on the sea floor, with an electric current flowing between them, calcium ions combine with carbonate ions and adhere to the structure (cathode).
4. Which of the following statement/s is/are true.
1. CRISPR gene editing is a genetic engineering technique in molecular biology by which the genomes of living organisms may be modified.
2. It is based on a simplified version of the bacterial CRISPR-Cas9 antiviral defense system.
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Ans: c
Justification:
- CRISPR gene editing is a genetic engineering technique in molecular biology by which the genomes of living organisms may be modified. It is based on a simplified version of the bacterial CRISPR-Cas9 antiviral defense system. By delivering the Cas9 nuclease complexed with a synthetic guide RNA (gRNA) into a cell, the cell’s genome can be cut at a desired location, allowing existing genes to be removed and/or new ones added in vivo.

(a) Yakshaghana
(b) Karnatic Music
