Answer: Lexington would talk about how important is work for teenagers, since the story of the hardworking Reagan is presented as an example.
Explanation: Lexington presents Reagan's story as a way of differing with many americans that claim summer jobs to be boring. Reagan was a harworker young man, who worked as a lifeguard, but in comparison to some teenagers, he would take it seriously to the point of saving people's lives from a river and scold them for it. He would wake up early and do his job for 12 hours a day, seven days a week. Therefore, If Lexington is presenting Reagan's hard routine, he would answer to a question like that by making the difference between lazy teenagers that complain about muscle ache and how they should value it, like Reagan.
