At a train station, four friends place their luggage in separate lockers before going sightseeing. Adam puts his suitcase in Locker A, Beth puts hers in Locker B, Carl puts his in Locker C, and Dana puts hers in Locker D. Later, a security officer moves the suitcases around due to a maintenance issue, placing Adam's suitcase in Locker D, Beth's suitcase in Locker A, Carl's suitcase in Locker B, and Dana's suitcase in Locker C. When the friends return to collect their luggage, where will each person initially search for their suitcase? Provide a very brief response.
When the friends return, they won't be aware of the switch made by the security officer. Adam will initially search for his suitcase in Locker A because that's where he placed it earlier. Beth will look in Locker B for similar reasons. Carl will go to Locker C, and Dana will head to Locker D, as they all expect to find their luggage in the lockers where they initially left them. Each friend will start their search based on their original action, not knowing about the subsequent changes.
