question:  Which of the follow characteristics does NOT give Moran the impression that the planet that the Nadine is approaching may be habitable?
context: 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. From the viewpoint of the Nadine's ship's company, it was simply necessary to get rid of Moran. The Nadine was out of overdrive and all the uncountable suns of the galaxy shone steadily, remotely, as infinitesimal specks of light of every color of the rainbow. Now it lay astern, and Moran could see the planet that had been chosen for his marooning. 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. A large cap would have meant a large area with arctic and sub-arctic temperatures, with small temperate and tropical climate-belts. 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. But since there were ice-caps there would be temperate regions. In short, the ice-cap proved that a man could endure the air and temperature conditions he would find. 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. Moran couldn't have bought a ticket, but he'd tried to get off the planet Coryus on the Nadine . Blaster in hand, he'd made the Nadine take off from Coryus III with a trip-tape picked at random for guidance. The process would be to find a planet and check its climate and relationship to other planets, and its flora and fauna against descriptions in the Directory. If they left a beacon, they may have left an identification of the planet.
output:  location of the ice cap
options:  shape of the ice cap  composition of the ice cap  location of the ice cap  size of the ice cap
