Which scientific or technological advance did not take place in the first fifteen years of the twentieth century?

A. Albert Einstein's theory of relativity
B. Wireless communication across the Atlantic
C. The creation of the internet
D. The invention of the airplane
E. The mass production of cars

It's (c). I would say (b), too, but Morse code can be considered wireless if flashes are used to send messages.

The correct answer is C, 'The creation of the internet,' as it was not developed until the late 20th century. Other options, such as Einstein's theory of relativity and the invention of the airplane, occurred within the first fifteen years of the 1900s. The internet's development began in the 1960s, far beyond this timeframe.
