 Which is the best characterization of why Stinson decided he did not want to bring his people to this planet?
Stinson lay still in the sand where he fell, gloating over the success of his arrival. He touched the pencil-line scar behind his ear where the cylinder was buried, marveling at the power stored there, power to fling him from earth to this fourth planet of the Centaurian system in an instant. A gray, funnel-shaped cloud of dust stood off to his left. Weather control made cyclones and other climatic phenomena on earth practically non-existent. The cloud did not move, though, except to spin on its axis rapidly, emitting a high-pitched, scarcely audible whine, like a high speed motor. He stood on a wide valley floor between two mountain ranges. Dark clouds capped one peak of the mountains on his left. He was here and Earth was somewhere up there. The sun shone obliquely, throwing Stinson's shadow upon the sand. Again Stinson felt the urge to run, or to use the cylinder to project himself somewhere else, but he said, "No!" very firmly to himself. He was here to investigate, to determine if this planet was capable of supporting life. He examined the wind devil as closely as he dared, but it was composed only of grains of sand. There was no core, no central place you could point to and say, here is the brain, or the nervous system. But then, how could a group of loosely spaced grains of sand possibly have a nervous system? When it changed to a cube he drew a square, a circle for a sphere, and so on. He became so absorbed in doing this that he failed to notice how the wind devil drew closer and closer, but when he inhaled the first grains of sand, the realization of what was happening dawned with a flash of fear. As he stood beside a small creek, a chill wind blew from the northwest. From one angle they were animals, from another birds, from a third they were vaguely humanoid creatures, glowering at him with primitive ferocity. No definable form or sculptured line was visible, yet he felt, or saw—he did not know which senses told him—the immeasurable gulf of a million years of painful evolution. These creatures were not only humanoid, but definitely human, although more slight of build than earth people. "My name is Stinson," he said, pointing to himself. He pointed upward, described a large circle, then another smaller, and showed how Earth revolved around the sun.
