 Which is the most accurate description of the planet Stinson finds himself on?
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. He was here and Earth was somewhere up there. He was here to investigate, to determine if this planet was capable of supporting life. There was no core, no central place you could point to and say, here is the brain, or the nervous system. When it changed to a cube he drew a square, a circle for a sphere, and so on. "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. But up to now the tube and the chain was the only evidence of an advanced technology, unless the ancient inscriptions in the stone wall of the pool, and the statues lining the wall were evidences. Stinson looked at the wind devil, since it could be no one else speaking, and pointed to himself. "I am Stinson, of the planet Earth." These are the undesirables, the incorrigibles, the nonconformists from the sixth planet.
 Some kind of penal colony
 A haven for amphibious creatures  A research outpost for discovering new species  Some kind of penal colony  An abandoned desert planet that cannot sustain life
