Final answer:
Macbeth's ambition and trust in the witches' first accurate prophecy lead him to disregard the duplicity of their statements, influenced by Lady Macbeth, he overlooks the prophecies' double meanings.
Step-by-step explanation:
Macbeth's failure to recognize the duplicity in the apparitions' statements is rooted in his overwhelming ambition and the deceptive nature of the witches' prophecies. When the witches proclaim that Macbeth will become the Thane of Cawdor and then king, his ambition blinds him to the possibility of deceit. Despite the initial skepticism, the accuracy of the first prophecy concerning the title of Thane of Cawdor leads Macbeth to trust in the witches' second prophecy — that he will be king. This trust is cemented when Lady Macbeth manipulates him into murdering King Duncan to fulfill the witches' prophecy.
Macbeth's desire to believe in a fate that elevates his status makes him overlook the true intentions behind the witches' cryptic statements. Lady Macbeth's influence also reinforces Macbeth's resolve and contributes to his inability to see through the double meanings in the prophecies. As a result, Macbeth misinterprets the warnings given by the apparitions as assurances of his invincibility and inevitability of his reign.
