Kuno is one of the main characters. He is different from others as he has a sense of rebellion against the all - controlling machine.
There are also other minor characters who are all part of this society ruled by the machine. But Kuno and Vashti are the ones through whom the story's major themes are explored.
There is Vashti, who is one of the main characters. She is used to the life controlled by the machine and represents those who are deeply entrenched in the machine - dominated world.
One main theme is over - reliance on technology. In the story, people depend so much on the machine that they lose their basic survival skills and connection with nature.
I don't have enough information to determine the main characters. It could be a scientist who invents or studies the machine, a curious child who stumbles upon it, or a group of adventurers who are on a quest related to the machine.
The main character is the Time Traveller. He's the one who builds the time machine and goes on the journey through time. Then there are the Eloi and the Morlocks. The Eloi are the gentle, child - like beings in the future, and the Morlocks are the more menacing, subterranean creatures.
There's also the emperor. He is a very important character as he represents the power and the establishment. His reaction to the flying machine is crucial in driving the story forward. When he sees the flying machine, he has to decide what to do about this new and potentially dangerous thing in his kingdom.
The main character is the inventor of the sound machine. There's also a doctor who the inventor tries to talk to about his discovery.
The main idea is about a world where people rely completely on a machine. It shows how this over - dependence has both physical and psychological impacts on the society.
I'm not entirely sure as I haven't read it recently, but usually there would be the scientists or military personnel involved with the machine.
Maybe the main characters are a curious student who first finds the answering machine and a school technician who tries to keep it running. There could also be a principal who has to deal with the consequences of whatever the answering machine does or doesn't do.
The Doctor is most likely one of the main characters. There could also be his companions, though without more specific knowledge about this short story, it's hard to say exactly who else.
