2. Akbar popularized the device of cooling water using saltpeter.
Which of the statements given above is/are NOT correct?

[A] 1 only

[B] 2 only

[C] Both 1 and 2

[D] Neither 1 nor 2

Answer: A

The method of water-lift based on pin-drum gearing known as Persian wheel had been introduced during Babur’s time.  

  • A complicated system of water lift by a series of gear-wheels had been installed in Fatehpur Sikri.  
  • Akbar was also credited with popularizing the device of cooling water using saltpetre. 
  • In metallurgy, the inability to produce cast iron remained an obvious drawback.  
  • As Irfan Habib observed, ‘India’s backwardness in technology was obvious when the matchlock remained the most common weapon in Indian armies. In Europe the flintlock had long come into use.  
  • Indians continued to use the expensive bronze cannon, long after these had become obsolete in Europe.  
  • This was because of India’s inability to make cast iron even in the seventeenth century.’
