Task: Question Generation
Input (English): Passage: Elvira Kent and her husband Michael suspect each other of cheating. For their wedding anniversary, Elvira books an ocean cruise to Rio de Janeiro but  her husband claims that unexpected business will prevent him from going. Seeing an opportunity, Elvira pretends to take the trip alone, but in fact sends singer Georgia Garrett, a woman she'd met at the travel agency, in her place and under her name. By secretly staying behind, Elvira hopes to find out if Michael is indeed sneaking around behind her back. Michael, however, is suspicious over Elvira's supposed willingness to go on the trip alone, and so hires private detective Peter Virgil to see if she is sneaking around behind his back.
Peter joins the cruise and, as part of his job, becomes acquainted with Georgia. Georgia, following the instructions of the real Elvira, keeps up the ruse by pretending to be Elvira to everyone, including Peter. Georgia and Peter are attracted to each other and gradually fall in love, which causes conflict for both of them.
During one of the cruise stops, Georgia's friend, Oscar Farrar, comes on board. Oscar is in love with Georgia despite Georgia's lack of interest in him, and when Peter spots them together, he thinks he has discovered the identity of Elvira's lover.
The film's third act is set in a Rio hotel, where all the principal characters converge and ride a merry-go-round of mistaken identities. Sorting out their true identities, resolving the crossed love plots, concludes the picture.
Output (English): What is the full name of the person who thinks they have discovered the identity of someone's lover?
