Task: Question Generation
Input (English): Passage: At Middlebury College in 1969, four young friends, Annie MacDuggan, Elise Elliot, Brenda Morelli, and Cynthia Swann, are graduating. Excited for the future and the potential it holds, the girls enthusiastically make a champagne toast celebrating their graduation as well as their friendship. As graduation gifts, valedictorian Cynthia presents the girls with matching Bulgari pearl necklaces. As the graduates take a commemorative picture of the four of them (presumably for the last time), Cynthia makes Annie, Brenda and Elise promise that they will always be there for each other throughout the remainder of their lives.
In the present time, the four friends eventually lose touch with one another, as evident when Cynthia is tearfully gazing at the picture of the four of them on that graduation day. Now wealthy and living in a luxurious penthouse, she gives her maid her own Bulgari pearl necklace (matching the three she gave to her friends on graduation day), and has the maid mail letters to them. She later walks outside on the balcony of her penthouse in a floor length fur coat, a cigarette and a drink, and then commits suicide by jumping to her death after learning through the tabloids that her ex-husband Gil (whom Cynthia made wealthy through her connections, according to narrator Annie) married his much younger mistress the day before.
Output (English): What is the last name of the person who makes the girls promise they will always be there for each other?
