question:  What was the indication in the passage to show that Starre was aware of Parker's newfound love for her?
context: [Transcriber's Note: This etext was produced from Planet Stories Summer 1945. "She checks down to the last dimension," Bob chortled, working with slide-rule and logarithm tables. "Now all we have to do is find out if she's made of tungsten, iron, quartz crystals, and cinnabar! Moments later, they were outside the ship, with star-powdered infinity spread to all sides. The ethergram read: Received your advertising literature a week ago. Bob Parker had received that ethergram three weeks ago. 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. He and Queazy caught up with her on the side of the asteroid they hadn't yet examined. About twenty steps away was her small dumbbell-shaped ship, so shiny and unscarred that it reflected starlight in highlights from its curved surface. But to us—to me and Queazy here—it means our business. In another second, Bob was standing next to her. "It's—it's very important that this—this asteroid stay right where it is," she said huskily. The big ship had landed, and little blue sparks crackled between the hull and the asteroid as the magnetic clamps took hold.
output:  His affection while teaching her about the mechanics of the hauler.
options:  His decision to not deliver the asteroid to her grandfather for the wedding.  His protectiveness over her towards Queazy.  His determination to help her stop the wedding to Mac.  His affection while teaching her about the mechanics of the hauler.
