George Washington Carver and Lewis Latimer are known for which contributions?

• A. Establishing civil rights law firms.
• B. Early abolitionist work.
• C. Inventions in astronomy and physics.
• D. Carver advanced agricultural methods and crop diversification; Latimer contributed to improvements in electric lighting and the development of the light bulb.

Answer: (D)

George Washington Carver’s impact comes from his approach to restoring soil health and expanding agricultural options. He championed crop diversification and rotation, showing how planting nitrogen-fixing crops like peanuts and sweet potatoes could rebuild depleted soils and provide farmers with alternative, profitable crops beyond cotton. Lewis Latimer’s contribution lies in electric lighting technology. He helped improve the carbon filament and contributed to the development of practical incandescent bulbs, making electric lighting more durable and accessible. These two figures are celebrated precisely for advances in agriculture and technology, not for civil rights law, abolitionist work, or fields like astronomy and physics. That combination is what makes this choice the best fit.
