 Which of the follow characteristics does NOT give Moran the impression that the planet that the Nadine is approaching may be habitable?
The plans were thrashed out very painstakingly, in formal conference on the space-yacht Nadine , with Moran present and allowed to take part in the discussion. The ice-cap, by its existence and circular shape, proved that the planet rotated at a not unreasonable rate. A water-ice ice-cap said that there were no poisonous gases in the planet's atmosphere. The fact was verified by the thick, dense cloud-masses which covered most of the surface,—all the surface, in fact, outside the ice-cap. Moran observed these things from the control-room of the Nadine , then approaching the world on planetary drive. Two of the Nadine's four-man crew watched out the same ports as the planet seemed to approach.
