{'answer_start': array([-1]), 'answer_text': array([''], dtype=object)}
In the 20th episode of The Americans, "Arpanet", Nina, a KGB double agent, misleads her FBI handler after receiving coaching on how to beat the polygraph from Oleg, her Soviet superior. Oleg describes the machine as being similar to a camera in that it does not know if the subject's smiles convey genuine happiness. He also uses the asp killing Cleopatra as a metaphor, stating it only killed her when she moved. One technique suggested to Nina is visualizing her KGB superior in the room, as well as clenching her anus. She appears to utilize and benefit from these techniques as she passes the test.
