Which group best describes the order of events in the development of the airplane?
Group A
Hot-air balloon flights pioneer air travel
Aviators fly gliders—heavier-than-air aircraft with no engines
Development of engine-powered machines with propellers and lightweight motors
First-ever flight across the English Channel
Construction of the first military airplanes
World's first scheduled commercial airline
Group B
Development of engine-powered machines with propellers and lightweight motors
World's first scheduled commercial airline
First-ever flight across the English Channel
Hot-air balloon flights pioneer air travel
Aviators fly gliders—heavier-than-air aircraft with no engines
Construction of the first military airplanes
I would have to say Group A. It makes more sense in that order. Group B goes from planes to hot air balloons to air crafts without engines, which is less developed by each one making Group A more likely to be correct.
