Consider the following pairs: 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?

Only one pair is correctly matched. The Flying Shuttle was invented by John Kay in 1733 — correctly matched. The Water Frame was invented by Richard Arkwright (not James Hargreaves) in 1769. The Spinning Jenny was invented by James Hargreaves (not Richard Arkwright) in 1764. Hence pairs II and III are swapped and only one pair (I) is correctly matched.
