In what year did Major Harrison invent the first sprinkler head but not patent it?

• A. 1865
• B. 1864
• C. 1860
• D. 1869

Answer: (B)

This question tests the difference between when something is invented and whether it’s patented. When we’re asked for the year Major Harrison invented the sprinkler head but did not patent it, we’re looking for the year of the actual creation, not a filing date or grant date for a patent. The historical record places the invention in 1864, and there’s no patent tied to that invention. So the year that fits the scenario—the moment of creation without patent protection—is 1864. The other years would imply a different timing or a patent event, which isn’t what the question describes.
