At a zoo, four friends - Emma, Frank, Grace, and Harry - decide to split up and explore different areas. Emma goes to see the giraffes, Frank visits the monkeys, Grace heads to the reptile exhibit, and Harry checks out the birds. Before they leave, each friend buys a souvenir: Emma gets a stuffed giraffe, Frank purchases a monkey keychain, Grace acquires a snake bracelet, and Harry buys a bird poster. They agree to meet at the entrance after an hour but get delayed due to various reasons. What does each friend think about the others' whereabouts and souvenirs when they finally reunite?

Respond briefly.
When the friends reunite at the entrance, they each observe the souvenirs the others purchased and make assumptions about what the others saw based on those items. Emma has a stuffed giraffe, which would naturally lead her friends to guess that she visited the giraffes, since her souvenir directly relates to that animal. Frank has a monkey keychain, so it would be logical for the others to infer that he spent his time at the monkey exhibit, as his keychain is a miniature representation of the animals commonly found there. Grace is wearing a snake bracelet, allowing the others to conclude she explored the reptile exhibit, considering the bracelet features an animal that is typically highlighted in such a section of a zoo. Lastly, Harry has a bird poster, which would suggest to his friends that he went to see the birds, as the poster is likely adorned with images of birds he saw there.

In essence, each friend's chosen souvenir acts as a clear indicator of their respective visited exhibits, and they would each make these connections upon seeing the others' souvenirs.
