In a large office building, there are four coworkers: Jethro, Prisca, Elodie, and Xiang. Jethro left his favorite pen, a rare collector's item, in a conference room after a meeting. Prisca, who had the next meeting in the conference room, found the pen but was unaware it was Jethro's. She thought it was cheap and left it on a table in the break room. Elodie saw the pen in the break room, recognized that it was a collector's item, and knowing Jethro collects such pens, took it and kept it in her desk for safekeeping without telling anyone. Xiang overheard Jethro mentioning his lost pen to another coworker but did not see Prisca find it or Elodie take it later. Jethro decides to ask his coworkers if they've seen it. Who should he expect to have the most useful information about the pen's whereabouts, and why? Provide a brief response.
Jethro should expect Elodie to have the most useful information about the pen's whereabouts. Jethro is unaware of where his pen went after he left it in the conference room. Prisca saw the pen but did not recognize its value and, thinking it was cheap, left it in the break room. Without knowledge of its ownership or value, she likely did not pay attention to its fate afterward. Therefore, she cannot offer Jethro information regarding its current location. Xiang is only aware that Jethro has lost a pen but has no information about the pen's movements after Jethro lost it, nor does Xiang know its appearance to identify it as Jethro's. Elodie not only recognized the pen as a collector's item but also knew that Jethro collects such items. She then purposely took it and kept it in her desk for safekeeping. Since Elodie's actions were deliberate and based on her knowledge of Jethro's collection habits, she is the only one among the coworkers who knows the precise current location of Jethro's pen. Therefore, upon asking, Jethro will find that Elodie will have the most useful information to help him recover his lost pen.
