question:  How would Eddie's reaction to the missing isotope been different if he had not been so knowledgeable about radioactivity?
context: Eddie Taylor would like to have finished it, but the bar of morning sunlight poking in under the window shade pried his eyes open. Still, one clue is as good as another when it comes to hunting uranium ore, I guess. It could start cavities. Get at it right away, and you’ll still have time to hunt your uranium. In fact, anything having to do with atomic science excited him. You couldn’t have a father who was head of the atomic-science department at Oceanview College without picking up a little knowledge along the way. Eddie knew that a radioisotope was a material which had been “cooked” in an atomic reactor until it was “hot” with radioactivity. When carefully controlled, the radiation stored up in such isotopes was used in many beneficial ways. One reason for asking that particular question was to keep from prying deeper into the subject of the radioisotope. His father usually volunteered any information he wanted known, so Eddie stuck to questions which could and would be answered. At the speed atomic science is moving today, we simply can’t afford to waste time. The best way to get there was by rowboat across Moon Bay, and that was too long a row to be starting now. Besides, there were plenty of other places around the outskirts of Oceanview where likely looking rock formations invited search with a Geiger counter. Eddie didn’t figure a girl would make a very good uranium prospecting partner, but most of the fellows he knew were away at camp, or vacationing with their folks, or something like that. 20 Eddie went inside and followed Teena to the kitchen. They had been ever since Eddie’s family had moved to Oceanview and his father had become head of the college’s atomic-science department. Teena’s father was chief engineer for the Acme Aviation Company, one of the coast town’s largest manufacturing concerns. 22 “Oh, yes, it’s fun, Mother,” Teena replied, wrapping wax paper around a sandwich.
output:  He would not have cared because he would be disinterested in the situation.
options:  He would have been very worried due to the severity of the situation.  He would not have cared because he would be disinterested in the situation.  He would have been extremely curious about the situation.  He would have found a way to be more helpful for his father's situation.
