Solution: d)

Mixed Farming 

Mixed farms are moderate in size and usually the crops associated with it are wheat, barley, oats, rye, maize, fodder and root crops. Fodder crops are an important component of mixed farming. Crop rotation and intercropping play an important role in maintaining soil fertility. Equal emphasis is laid on crop cultivation and animal husbandry. Animals like cattle, sheep, pigs and poultry provide the main income along with crops.

Solution: c)

• A fuel-cell electric vehicle is essentially a hybrid electric vehicle wherein, the internal combustion engine is replaced with a fuel-cell stack. The onboard sources of power include hydrogen as well as an 
• advanced battery system. 
• The fuel cell combines hydrogen and oxygen to generate an electric current, water being the only byproduct. 
• Fuel cells generate electricity through an electrochemical process. 
• And, there are no moving parts in the fuel cell, so they are more efficient and reliable by comparison.

How is it different from an electric vehicle (EV)? 

Unlike a battery-electricity vehicle, it does not store energy and, instead, relies on a constant supply of fuel and oxygen — in the same way that an internal combustion engine relies on a constant supply of petrol or diesel, and oxygen.

Solution: d)

• The Governor (Article 213) has the power of making ordinances when both houses of the legislature are not in session, which has the same status as that of a law of the legislature. 
• His ordinance-making power is coextensive with the legislative power of the state legislature. This means that he can issue ordinances only on those subjects on which the state legislature can make laws.
• He can withdraw an ordinance at any time.

Solution: b)

Zero tillage is the process where the crop seed will be sown through drillers without prior land preparation and disturbing the soil where previous crop stubbles are present. 

Zero tillage not only reduce the cost of cultivation it also reduces the soil erosion, crop duration and irrigation requirement and weed effect which is better than tillage. Zero Tillage (ZT) also called No Tillage or Nil Tillage. Adopting no-tillage in agro-ecosystems has been widely recommended as a means of enhancing carbon (C) sequestration in soils. 

Vertical farming is the practice of growing produce in vertically stacked layers. The practice can use soil, hydroponic or aeroponic growing methods. Vertical farms attempt to produce food in challenging environments, like where arable land is rare or unavailable.
