question:  Why were the Space Scouts sent on their mission?
context: So when the Chief of World Security told him that he had been selected as the answer to the Solar System's greatest mystery, Jery assumed that it was because of his mental agility.

He'd spoken with evidence of utmost candor, and the Chief of Interplanetary Security was not one to be accused of a friendly josh, but—"You're kidding!" "You were chosen, from all the inhabitants of this planet, and all the inhabitants of the Earth Colonies, by the Brain."
