 Which term best describes Pop's attitude toward his lunar occupation?
Once in two weeks Earth-time a rocketship came around the horizon from Lunar City with stores for the colony deep underground. When it was first found, scientists descended into it to examine the exposed rock-strata and learn the history of the Moon before its craters were made. In the Moon's slight gravity, a man is really adjusted to existence when he has a well-developed case of agoraphobia. There was a warning-bell in the shack, and when a rocketship from Lunar City got above the horizon and could send a tight beam, the gong clanged loudly, and Pop got into a vacuum-suit and went out the air lock.
