Where is the laboratory of the famous inventor Thomas Edison located?

• A. Menlo Park, NJ
• B. Newark, NJ
• C. Philadelphia, PA
• D. Boston, MA

Answer: (A)

The laboratory of Thomas Edison, famously known as the Menlo Park laboratory, is located in Menlo Park, New Jersey. This site became notable in the late 19th century as one of the first modern research and development facilities. Edison's work there led to numerous inventions, including the phonograph and improvements to the electric light bulb, marking a significant shift in technological innovation.

While the other locations mentioned have their own historical significance, they are not associated with Edison's primary laboratory. Newark, Philadelphia, and Boston have rich histories of invention and invention-related activities, but it was at Menlo Park where Edison established a systematic approach to invention that included collaboration with other engineers and large-scale experimentation. This method contributed to his success as one of America's greatest inventors.
