<passage>:
Irgi was the last of his monster race, guardian of a dead planet, master of the secret of immortality. It was he whom the four men from Earth had to conquer to gain that secret—a tentacled monstrosity whom Earthly weapons could not touch. Irgi was the last of his race. There was no one else, now there had been no others for hundreds and hundreds of years. Irgi had lost count of time dwelling alone amid the marble halls of the eon-ancient city, but he knew that much. There were no others. Only Irgi, alone. clinging shelter, destroying dust and germs. Irgi had discovered the mist many years ago, when it was too late to save his kind. He had flung a vast globe of transparent metal above this greatest of Urg and set them up. Irgi enjoyed beauty, and he enjoyed work. It was In the doorway, Irgi paused and ran his eyes about the chamber, sighing. block possess. There was nothing they could not do, if Irgi so willed. Irgi moved across the room. He pressed glittering jewels inset in a Irgi drew himself upwards, slowly turning, laving in the quivering Irgi was immortal, and the blue light made him so. and nourished." He touched the jeweled controls, shutting the power to a low murmur. He "I must speak," Irgi said as he moved along the corridor. "I have not spoken for many weeks. I must exercise my voice, or lose it. That is the law of nature. It would atrophy, otherwise. "Yes, I will use my voice tonight, and I will go out under the dome and will talk to them and tell them how lonely Irgi is." and the name and fame of Irgi means nothing to the walls of my city, nor to the Chamber of the Cones, nor even—at times—to Irgi himself." It was a spaceship. Emerson took his hands from the controls of the gigantic ship that hurtled through space, and wiped his sweaty palms on his thighs. His "The last planet in our course," he breathed. "Maybe it has the radium!" "Yes," whispered the man beside him, wetting his lips with his tongue. "No use to think of failure. If it hasn't, we'll die ourselves, down there." Radium. And the Plague. It had come on Earth suddenly, had the Plague, back in the first days of space travel, after Quigg, the American research scientist at Cal Tech, discovered a way to lift a rocket ship off the Earth, and propel it to the Moon. They had been slow, lumbering vessels, those first spaceships not at all like the sleek craft that plied the voids today. But it had been a beginning. And no one had thought anything of it when Quigg, who had made the first flight through space, died of cancer. As the years passed to a decade, and the ships of Earth rode to Mars and Venus, it began to be apparent that a lifetime of space travel meant a hideous death. Scientists attributed it to the cosmic rays, for out in space there was no blanketing layer of atmosphere to protect the fleshy tissues of man from their piercing power. It had long been causing the unorderly growth of new cells that man called cancer, the cosmic rays were destroying the life they had created. It meant death to travel in space, and only the stupendous fees paid to the young men who believed in a short life and a merry one, kept the ships plying between Mars and Earth and Venus. Lead kept out the cosmic rays, but lead would not stand the terrific speed required to lift a craft free of planetary gravity space were segregated, but the damage had been done. The Plague spread, and ravaged the peoples of three planets. it out among the stars to find the precious radium in sufficient quantities to halt the Plague. It had not been easy to find a crew. The three worlds knew the men were going to their doom. It would be a miracle if ever they reached a single planet, if they did not perish of space cancer before their first goal. Carson Nichols, whose wife and children were dying of the God—" Mussdorf erupted laughter. "For what? How do we know what they're like? An inhabited planet doesn't mean men. We found that out—several times." A section of the globe slid back, and the spaceship moved through the opening. The globe slipped back and locked after it. "They have us now," grunted Mussdorf. He slid his fingers along the transparent window, pressing hard, the skin showing white as his "Think it's safe to go out?" asked Nichols. "Try the atmospheric recorder," said Emerson. "If the air's okay, I'd like to stretch my own legs." No disease." He began to laugh, then caught himself. "No disease," he whispered, "and every one of us is going to die of cancer." Mussdorf came up through the trap and passed out the sun-blasters. They The big Earthman was lifted high into the air, squeezed until his lungs nearly collapsed. He hung limp in a gigantic tentacle as Emerson ran Irgi stared at the things that lay on the white flagging. Queer beings He looked at the spaceship, ran exploring feelers over it. He cast a glance back at the creatures again, and shook his head. Strange beings they might be, but they had mastered interplanetary travel. Well, he'd always maintained that life would be different on other worlds. Life here on Urg took different patterns. Irgi bent to wrap long arms about the queer beings, lifting them. His knew a way to cure it. Irgi knew a way to cure anything. He carried these creatures easily, without trouble. The ease of his passage gave him time to think. He had been glad to find these creatures. They were someone to have to be prepared. And the preparation—hurt. Well, better a few moments of agony than a death through a worse. And if he could not speak to them, they could speak to him, through electrigraph screen. That should be absorbing. It made Irgi happy, reflecting upon it, and Irgi had not known happiness for a long time. Irgi dropped his burdens. With quick tendrils he adjusted straps to "It's short-circulated their nervous systems for a while, absorbed the electric charges all intelligent beings cast," Irgi said aloud, glad at this chance to exercise his voice. "They won't be able to feel for some time. When the worst pain will have passed, they will recover. And now "I wonder if they've perfected this," Irgi mused. "They must be aware grew nebulous, then cleared. Irgi A tall, lean man in white looked out at him. His lips moved, and Irgi plague. The thoughts of this Emerson were coming in clearer, as Irgi in Irgi stared upward at a colossal figure graven in lucent white marble. Irgi unfastened clamps, and rolled the screen aside. He reached to a Opening the laboratory door, Irgi passed out and closed it behind him. "Maybe—maybe he's vivisecting us," moaned Nichols. "With rays or—or something—aagh! I can't stand it!" "Hang on, kid," gritted Emerson, fighting the straps. "I think it's clanging against the tabletop as it ripped loose. Mussdorf held his arm aloft and laughed harsh triumph. "I'll have you all loose in a second," he grunted, ripping straps from

<question>:
What crucial point does Irgi fail to consider when he begins to act to save the people of Earth?

B It evidently does not occur to him that a frightened alien race that cannot communicate with him will interpret being restrained and subjected to the pain of the space cancer cleansing treatment as a hostile action.
C It never crosses his mind that some men are evil and selfish, and that some of his captives might not be people of goodwill.
D It evidently does not occur to him that he will not be able to travel to Earth with his equipment, and not enough people from Earth will be able to travel to Urg to make a difference.
