Which pairing is accurate according to the material?

Which pairing is accurate according to the material?

• A. Thomas Edison — First to mass market the lightbulb
• B. Thomas Edison — Arc lamp inventor
• C. Frank Hauskbee — Arc lamp inventor
• D. Humphrey Davy — First electric light

Answer: (A)

Distinguishing invention from commercialization helps explain why this pairing is accurate. The material credits Thomas Edison with mass-marketing the lightbulb—making it practical, affordable, and widely available through improved production and a complete lighting system. He didn’t invent the arc lamp; that early electric light was demonstrated by Humphrey Davy. Frank Hauskbee isn’t a standard historical figure associated with this invention. So the statement linking Edison to mass-market lightbulbs reflects the documented role of commercializing the technology, which is why it’s the best match.
