Which of the statements given above is/are NOT correct?
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.’
