Which of the following pairings is correct?

Which of the following pairings is correct?

• A. Henry Bessemer — Light bulb
• B. Henry Bessemer — Steel process
• C. Andrew Carnegie — Finance
• D. Wright Brothers — Oil

Answer: (B)

Matching inventors to their most famous contributions helps you see why this pairing is correct. Henry Bessemer developed the steelmaking process that bears his name, the Bessemer process, which turned molten pig iron into steel by blowing air through it to remove impurities. This innovation dramatically lowered the cost of steel and enabled rapid expansion of railways, buildings, ships, and machinery in the industrial era. Because of that, his association with steel production is the strongest among the options. The light bulb is associated with Thomas Edison, not Bessemer. Carnegie is best known as a steel industrialist and philanthropist, not primarily as a financier. The Wright Brothers are pioneers of aviation, not oil.
