The underlined prepositional phrases "in the tree" are considered misplaced in the sentence "The camera in the tree awakened the baboon in the tree."
The phrase appears twice, and as it stands, it can create confusion about which noun it is referring to—whether the camera or the baboon is in the tree. To clarify, you could rephrase the sentence, for example: "The camera that was in the tree awakened the baboon that was also in the tree." This way, each subject is clearly linked to their respective prepositional phrase.
