Question

In which decade did both automobile and air travel become popular and convenient

Answer 1

The correct answer is the 1920s. This was a period called the roaring twenties and that's when the economy started booming thanks to the development of the industry. Everyone now had a Ford car and airplanes became one of the favorite means of tranportation, and they were mostly safe. Unfortunately, this age was followed by the great depression in the 30s.
