encountering the local fauna when it was over. Blast-rifles were not effective against such creatures as these. Torches were contact weapons but they killed. Blast-rifles did not. And Harper needed to pull himself The thing presumably died, but it continued to writhe senselessly. He turned to see other horrors crawling toward him. Then he knew he was being marooned on a planet of endless terrors. together again, too. Also, neither Moran nor any of the others wanted to Moran, naturally, did not mean to help in the carrying out of the plans separate—on the whitish ground-stuff. Moran had disliked such creatures system in which human beings belonged had turned out to be infinitely complicated. It had turned out, in fact, to be the ecological system of necessary to get rid of Moran. In their predicament he might have come to the same conclusion but he was not at all enthusiastic about their decision. He would die of it. The humanity spread through the galaxy with an attendant train of insects and annoyances. If they left their pests behind, the total system of checks and balances which make life practical would get lopsided. It Nadine would not maintain itself. The vagaries that could result were admirably illustrated in and on the landscape outside the could see the planet that had been chosen for his marooning. It was a . Something had been left out of the seeding of this planet. The element—which might be a bacterium or a virus or almost anything at all—the element that kept creatures at the size called "normal" was either missing or inoperable here. The results were not desirable. much. A water-ice ice-cap said that there were no poisonous gases in the planet's atmosphere. Sulfur dioxide or chlorine, for example, would not allow the formation of water-ice. It would have to be sulphuric-acid or The ice-cap, by its existence and circular shape, proved that the planet rotated at a not unreasonable rate. The fact that it was water-ice told 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 approaching the world on planetary drive. He was to be left here, with Moran disagreed, but he did not answer. He cocked an ear instead. He passage leading away. He called. But Moran observed with grudging investigation. Moran, at least, would be picked out as a fugitive from Moran did not know. They might be sent back where they came from. In Moran stirred, and he knew that every one of the others was conscious of when Moran had used desperate measures against them. emergency-kit, anyhow." The emergency-kit contained antiseptics, seeds, and a weapon or two, with elaborate advice to castaways. If somebody were wrecked on an even possibly habitable planet, the especially developed seed-strains would provide food in a minimum of time. It was not an encouraging thought, though, and Moran grimaced. Moran wondered, momentarily, what sort of world they came from and why government would think defeat. Moran's own situation was perfectly anybody, and somebody formerly in very great danger would now be safe, which was the reason for what Moran had done. But the dead man had been very important, and the fact that Moran had forced him to fight and killed him in fair combat made no difference. Moran had needed to get off-planet, and fast. But space-travel regulations are especially designed to prevent such escapes. for departure had been granted. But Moran had waylaid the messenger was out of overdrive they efficiently gave him his choice of surrendering or else. He surrendered, stipulating that he wouldn't be landed back on Coryus he still clung to hope of avoiding return—which was almost certain anyhow. Because nobody would want to go back to a planet from which they'd carried away a criminal, even though they'd vegetation on a planet with a sol-type sun. shared the peculiarity of the ground as far as they could see through the haze. It was not vegetation in any ordinary sense. Certainly it was no mineral surface! The landing-pockets had burned away three or four feet of it, and the edge of the burned area smoked noisesomely, and "It's a ship," said Moran curtly. "It crash-landed and its crew set up a "Naturally!" "Then since I can't be trusted with a weapon," said Moran, "I suggest that I take a torch. We may have to burn through that loathesome stuff to get in the ship." Moran silently went to the space-suit rack and began to get into a "If there's a lifeboat left," said Carol suddenly, "Moran might be able world. Moran, though, would not be permitted a weapon. He picked up a suits would take care of that. Anyhow the ice-cap said there were no water-soluble gases in the atmosphere, and a gas can't be an active poison if it can't dissolve. They filed out of the airlock. They stood on ash-covered stone, only slightly eroded by the processes which made life possible on this landed. Moran moved scornfully Moran grunted. Distastefully, he saw his predicament made worse. He knew discovered. It had not been practical for men to move onto new planets operation was necessary before humanity could move in. A complete ecological complex had to be built up microbes to break down the rock for soil, bacteria to fix nitrogen to make the soil fertile plants to grow in the new-made dirt and insects to fertilize the plants so they would multiply, and animals and birds to carry the seeds planet-wide. On most planets, to be sure, there were local, aboriginal plants and animals. But still terrestrial creatures had to be introduced if a colony was to feed itself. Alien plants did not supply satisfactory "This ground stuff," said Moran distastefully, "is yeast or some sort of not wholly so. Once one mentioned yeasts and toadstools and fungi generally, the weird landscape became less than incredible. But it remained actively unpleasant to think of being marooned on it. "Suppose we go look at the ship?" said Moran unpleasantly. "Maybe you He and the others joined Moran on the yielding surface. Their footing Moran heard muffled noises in his helmet-phone as the others tried to harshly to the men with him "It's not a hunting creature on worlds where it's smaller. It's not likely to have turned deadly here. Come on!" He went forward over the singularly bouncy ground. The others followed. It was to be noted that Hallet the engineer, avoided the huge harmless creature more widely than most. They reached the mound which was the ship. Moran unlimbered his torch. the metal hull that had fallen here before his grandfather was born. Sometimes the flame cut across things that writhed, and he was sickened. But above all he raged because he was to be marooned here. He could not altogether blame the others. They couldn't land at any colonized world with him on board without his being detected as an extra member of the crew. His fate would then be sealed. But they also would be horribly. He got clear of the newly burned-away stuff. There was still much smoke Nadine . They need not maroon him. In fact, they wouldn't dare. as thoroughly as one that had too many. Perhaps more thoroughly. So if Harper were killed, Moran would be needed to take his place. He'd go on from here in the , necessarily accepted as a member of her crew.

<options>:

B His only option would be to prey on animals, bacteria, fungi, or other living creatures.
C He could use limited, fast-growing seed packets provided by the crew members of the Nadine.
D He would not have any viable chance of survival without non-toxic vegetation.

<answer>:

C
