question:  Which word doesn't describe the people of this futuristic city?
context: But some men aren't sane; thus it isn't always so! I'm not your father's ghost, even if I do look a bit like him. You will, you know, so why quibble about it? Yes, it'll be pretty obvious it must be a time machine. You'll be puzzling over what I'll tell you, and you'll be getting used to the idea that you are the man who makes atomic power practical. You are completely outside of time and space, as best you can guess how things are. Then it comes to you slowly that you're actually traveling in time. "Maybe it's no dimension—or it might be the fifth; if you're going to skip over the so-called fourth without traveling along it, you'd need a fifth. I figured out once that such a universe would need some seven or eight time and space dimensions. Maybe there is no machine, and it's just easier for us to imagine it. That means you either carry a small time field with you, or you are catching a small increment of time from the main field. Out there is neither time nor space, apparently. You feel a dankish sort of air replace the stale air, and you breathe easier, though we're in complete darkness, except for the weak light in the machine, which always burns, and a few feet of rough dirty cement floor around. "This is like the things they wear in this century, as near as I can remember it, and I should be able to pass fairly well. And it's a pretty easygoing civilization, from what I could see. He told me, just as I'm telling you, that it's an interstellar civilization." We have to walk up a flight of stairs, and there is an elevator waiting, fortunately with the door open. There's no feeling of acceleration—some kind of false gravity they use in the future.
