In paragraph 7, the author notes: "It should be pointed out here that the Wrights had to invent the propeller as a means of propulsion."

Do you think it is possible to invent something from nothing? Is that what the Wright brothers did? Explain your answer.

A. Yes, inventing something from nothing is possible.
B. No, the Wright brothers built upon existing knowledge.
C. Maybe, it depends on the definition of nothing.
D. Unsure, inventions are subjective.

No, the Wright brothers did not invent something from nothing. They built upon existing knowledge and made significant contributions to the development of powered flight. The Wright brothers combined scientific theory with careful experiments to refine their understanding of lift and control in flight. They also built upon the work of other pioneering engineers, such as Otto Lilienthal and Samuel Langley. Their successful invention of the airplane was the result of years of research, experimentation, and innovation.
