Kamau entered the living room and found an open novel on the coffee table. He knew that neither he nor his roommate, Priya, liked to read mystery novels, but their mutual friend, Leila, did. Leila had visited the apartment earlier that day while Priya was at work. Assuming Kamau hasn't talked to Priya or Leila about the novel, does Kamau have enough information to infer whose novel it is? Also, would Kamau know if Priya is aware that Leila visited today? Provide a brief response.
Based on the information that Kamau knows he does not like mystery novels and is also aware that Priya shares his disinterest in the genre, he can infer that the mystery novel likely belongs to someone who enjoys them, which in this case is their friend, Leila. Given that Leila visited earlier when Priya was at work and the presence of the open novel seems to indicate that someone had been reading it, Kamau could reasonably assume that the novel belongs to Leila. 

However, Kamau cannot know if Priya is aware that Leila visited unless he has confirmation from either Priya or Leila. The novel itself does not provide evidence that Priya knows of the visit--only that the visit occurred. If Priya returned from work after Leila's visit but before Kamau entered the living room, and noticed the novel, she might deduce that Leila had come by. Without having discussed this with Priya or witnessing a meeting between them, Kamau does not have enough information to determine Priya's awareness of Leila's visit. The knowledge about whether Priya is aware of the visit remains inconclusive for Kamau without further communication.
