question:  What happens at the second confrontation with the Saylor brothers?
context: And if The Interplanetary Hauling & Moving Co., hadn't been about to go on the rocks (chiefly due to the activities of Saylor & Saylor, a rival firm) neither Bob nor Queazy would have thought of sending an answering ethergram to Burnside stating that they would fill the order. And yet, if by some chance there was such a rigidly specified asteroid, their financial worries would be over. Now that he and Queazy had found the asteroid, they were desperate to get it to its destination, for fear that the Saylor brothers might get wind of what was going on, and try to beat them out of their profits. Now they scuffed along the smooth-plane topside of the asteroid, the magnets in their shoes keeping them from stepping off into space. By the naked eye, they could see iron ore, quartz crystals, cinnabar, but he had the spectroscope and there was no reason why he shouldn't use it. He satisfied himself as to the exterior of the asteroid, and then sent the twin beams deep into its heart. The radiations from the sundered molecules traveled back up the beams to the atomic-whirl spectroscope. Her expression darkened as she saw the completely instinctive way he was looking at her and her radioed-voice rapped out, "Now you two boys go and play somewhere else! He and Queazy caught up with her on the side of the asteroid they hadn't yet examined. I'm sure you don't understand the conditions—" The girl turned and drew a gun from a holster. If we don't take this asteroid to Earth before June 2, we go back to Satterfield City and work the rest of our lives in the glass factories. In another second, Bob was standing next to her. The big ship had landed, and little blue sparks crackled between the hull and the asteroid as the magnetic clamps took hold. The two men in the lead stood with their hands on their hips; their darkish, twin faces were grinning broadly.
output:  The yo-yo worked as intended after some maneuvering, damaging their ship.
options:  The yo-yo fails to hit the other ship, as it can't quite reach it.  The Saylor brothers call on the Interplanetary Commission for help.  The yo-yo worked as intended, hitting their ship with the first hit.  The yo-yo worked as intended after some maneuvering, damaging their ship.
