Kofi left his favorite hat on a bench in the park. Later that day, Yuna and Javier walk by the bench. Yuna had seen Kofi at the park earlier with the hat, but Javier had not. Yuna goes home before Javier and does not mention seeing the hat on the bench. When Javier walks past the bench, he does not notice the hat and continues walking. The following day, Kofi asks them both if they've seen his hat. What do Yuna and Javier respond, and why?

Respond very briefly.
Yuna tells Kofi that she saw his hat on the bench the previous day because she has the knowledge of both seeing Kofi with the hat earlier and noticing the hat on the bench. Her memory of these events allows her to make the connection and provide Kofi with accurate information about the whereabouts of his hat. Javier, on the other hand, tells Kofi that he has not seen the hat. Since he did not notice the hat on the bench when he walked past it, and he did not have prior knowledge that Kofi left it there, he does not have the necessary information to help Kofi. Additionally, since Yuna did not share the information about the hat being on the bench with Javier, he remains unaware of the situation regarding the hat's whereabouts.
