Explanation: personification is a figure of speech that consists in giving human characteristics to non human objects (or animals). In the given passage from "The Most Dangerous Game" we can see an example of personification in the phrase: "Can't see it," remarked Rainsford, trying to peer through the dank tropical night that was palpable as it pressed its thick warm blackness in upon the yacht, because it says that the night (non human object) is pressing its blackness upon the yacht (pressing is a human characteristic).
