Concept:The Industrial Revolution was driven by James Watt's fundamental improvement to the steam engine, which changed it from a simple water pump into a powerful and efficient source of rotary motion for factory machinery.
Explanation:We need to identify the historically correct statement among the four options.
Option A is incorrect. Thomas Savery invented an early steam pump, but the astrolabe is an ancient astronomical instrument invented long before his time.
Option B is incorrect. Thomas Newcomen invented the first practical atmospheric steam engine in 1712, which was primarily used for pumping water out of coal mines, not for inventing chemical dyes.
Option D is incorrect. Matthew Boulton was a successful businessman and manufacturer who financed and marketed James Watt's steam engine; he is not associated with any technique for refining gold.
Option C is correct. James Watt's key breakthrough was the separate condenser, patented in 1769. This made the steam engine dramatically more fuel-efficient and powerful.
Crucially, Watt's engine could produce continuous rotary motion, unlike the earlier reciprocating pump of Newcomen.
This rotary power was ideally suited to drive the belts, shafts, and machines of the new factories, particularly in textiles and metalworking.
Therefore, Watt's invention directly enabled the widespread mechanical power that characterizes the Industrial Revolution.
Answer:Option C: James Watt's invention converted the steam engine from being a mere pump into one which would provide energy to power machines in factories.
