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 necessary to get rid of Moran. In their predicament he might have come . 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 The ice-cap, by its existence and circular shape, proved that the planet Moran observed these things from the control-room of the Nadine , then approaching the world on planetary drive. He was to be left here, with no reason ever to expect rescue. Two of the "It doesn't look too bad, Moran!" Moran disagreed, but he did not answer. He cocked an ear instead. He They'd been on Coryus Three and they'd gotten departure clearance from its space-port. With clearance-papers in order, they could land unquestioned at any other space-port and take off again—provided the other space-port was one they had clearance for. Without rigid control of space-travel, any criminal anywhere could escape the consequences of any crime simply by buying a ticket to another world. Moran couldn't have bought a ticket, but he'd tried to get off the planet Coryus on the Nadine . The trouble was that the covering five persons aboard—four men and a girl Carol. Moran made six. its crew would spark an investigation. A lengthy, incredibly minute 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 effect, with six people on board instead of five, the she could. And Moran was the extra man whose presence would rouse take off from Coryus III with a trip-tape picked at random for guidance. But the trip-tape had been computed for another starting-point, and when the yacht came out of overdrive it was because the drive had been dismantled in the engine-room. So the ship's indefinite. A liner could re-locate itself without trouble. It had elaborate observational equipment and tri-di star-charts. But smaller craft had to depend on the Galactic Directory. 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. That was the way to find out where one was, when one's position became doubtful. The Nadine needed to make a planet-fall for this. "That's a marker," Carol announced. "I saw a costume-story tape once that had that sound in it. It marked a first-landing spot on some planet or other, so the people could find that spot again. It was supposed to be a long time ago, though." Moran stirred, and he knew that every one of the others was conscious of long habit. Burleigh said they'd been Underground people, fighting the government of their native world, and they'd gotten away to make it seem the revolt had collapsed. They'd go back later when they weren't expected, and start it up again. Moran considered the story probable. when Moran had used desperate measures against them. 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. government would think defeat. Moran's own situation was perfectly He'd killed a man on Coryus III. His victim would not be mourned by 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. He'd made a pretty good try, at that. One of the controls on space-traffic required a ship on landing to deposit its fuel-block in the space-port's vaults. The fuel-block was not returned until clearance for departure had been granted. But Moran had waylaid the messenger carrying the Nadine's fuel-block back to that space-yacht. He'd companions got the drive dismantled two days later and once the yacht 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 done it unwillingly. Investigation of such a matter might last for months. "It's a ship," said Moran curtly. "It crash-landed and its crew set up a signal to call for help. None came, or they'd have turned the beacon "Then since I can't be trusted with a weapon," said Moran, "I suggest 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 "Ah, yes!" said Moran. "It's very likely that the ship hit hard enough to kill everybody aboard, but not smash the boats!" "Somebody survived the crash," said Burleigh, "because they set up a landed. Moran moved scornfully Moran grunted. Distastefully, he saw his predicament made worse. He knew what had happened here. He could begin to guess at other things to be discovered. It had not been practical for men to move onto new planets and subsist upon the flora and fauna they found there. On some new planets life had never gotten started. On such worlds a highly complex operation was necessary before humanity could move in. A complete 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 food. So an elaborate adaptation job had to be done on every planet it, so somebody dumped germs and spores and bugs to make it ready for plants and animals eventually. But nobody's come back to finish up the job." 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 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 investigated. Official queries would go across this whole sector of the galaxy, naming five persons of such-and-such description and such-and-such fingerprints, voyaging in a space-yacht of such-and-such size and registration. The world they came from would claim them as fugitives. They would be returned to it. They'd be executed. . They need not maroon him. In fact, they wouldn't dare. A ship that came in to port with two few on board would be investigated Harper were killed, Moran would be needed to take his place. He'd go on , necessarily accepted as a member of her crew.

<question>:
Why does Moran think it could be beneficial if one of the crew members was killed on the alien planet?

<options>:
A He would be more likely to survive an attack from the Nadine crew if they ambushed him.
B He could convert their body to nutrients, which he could use to survive longer on the alien planet.
C He and the remaining crew members could pass security clearance with only five members on board.
D He could steal the deceased crew member's identity and use it to start a new life on a new planet.

<answer>:

C
