Inventions Inventors I. Flying shuttle loom John Kay II. Water frame James Hargreaves III. Spinning jenny Richard Arkwright
How many of the pairs given above are correctly matched?
One
To determine how many of the pairs are correctly matched, we must verify the inventors of each invention listed:
- Flying Shuttle Loom: This invention is correctly attributed to John Kay, who patented it in 1733. The flying shuttle significantly increased weaving speed, revolutionizing the textile industry at that time.
- Water Frame: This invention was actually created by Richard Arkwright, not James Hargreaves. Arkwright patented the water frame in 1769, which used water power to spin cotton threads far stronger than those spun by a hand-powered spinning jenny.
- Spinning Jenny: This was invented by James Hargreaves, not Richard Arkwright. The spinning jenny, invented in 1764, allowed one worker to spin multiple spools of thread simultaneously, significantly speeding up textile production.
Based on the above analysis, only one pair is correctly matched:
- Flying Shuttle Loom - John Kay
Therefore, the correct answer is: One.
