1. Emissions from cement manufacturing arise not only from the combustion of fossil fuels but also from the chemical decomposition of limestone during clinker production.
2. Increasing the share of renewable electricity in cement plants can eliminate the principal sources of carbon dioxide emissions from cement manufacturing without changes in the clinker production process.

Which of the following information supports/supports the above statement(s)?

1. During calcination, calcium carbonate decomposes into calcium oxide and carbon dioxide, releasing process emissions independent of the fuel used.
2. Portland Pozzolana Cement and Portland Slag Cement incorporate supplementary cementitious materials that can reduce the clinker content required per unit of cement.
3. Cement manufacturing requires high-temperature heating, and clinker is produced by heating raw materials in a kiln.

Select the answer using the code given below:

1. A country may remain vulnerable to supply disruptions despite diversifying its sources of mineral ores, if processing and refining capacities are concentrated in a few countries.
2. Financial hedging and physical stockpiling address identical dimensions of supply-chain risk and can therefore substitute for each other.

III. The effectiveness of strategic mineral reserves depends partly on whether the stored materials meet the processing requirements of downstream industries.

Which of the following inferences can be drawn from the above statements?

1. Diversification of mineral import sources may not ensure supply-chain resilience unless processing dependencies are also addressed.
2. Financial hedging can guarantee the physical availability of minerals during export restrictions or shipping disruptions.
3. The utility of strategic mineral reserves depends on the suitability of their contents for industrial use.

Select the answer using the code given below:

1. A Money Bill can be introduced only in the Lok Sabha.
2. The Rajya Sabha can amend a Money Bill with the prior approval of the President.
3. The President cannot return a Money Bill to Parliament for reconsideration.

Which of the statements given above is/are correct?
