Task: Question Generation
Input (English): Passage: After a hotel reservation mix up, two sisters Karen and Jennifer, and their friend Vicki Thompson, meet a friendly, but shady character named Ernest Keller who is the owner of a small town museum. Ernest convinces the three women into accepting an invitation for cheap room and board at his large farmhouse outside of town where his wife Virginia also lives. Once there, Jennifer and Karen leave for the holiday parade fair which Jennifer, a news reporter, is reporting on. At the festival, Jennifer is met by her soon to be ex-boyfriend, Tony, who gets her to stay behind to talk about their relationship.
Meanwhile, back at the house, Vicki prepares to take a nap in her room, but is attacked by an unseen figure. The unseen eventually begins to pull Vicki into a floor vent when she tries to escape. The grate of the vent slams down on her neck, killing her. At the parade, Karen leaves Jennifer and Tony to talk, and makes her way back to the house alone—where she too is then attacked and killed by the unseen, as it attempts to pull her by her scarf through a vent into the basement. Virginia, who had been in the barn slaughtering a chicken, soon after comes inside to find the bodies of both Vicki and Karen.
When Ernest arrives back at the house, he finds Virginia in shock. At this point, it is revealed through flashbacks that Virginia and Ernest are, in fact, brother and sister, and that Ernest had murdered his own sadistic father over 20 years ago in order to maintain the unnatural relationship. It is also revealed that they have an inbred son named "Junior" who has been kept locked up in the basement; the viewer also learns that Junior is often viciously beaten by Ernest. Ernest then convinces the subservient Virginia, who the viewer now realizes is taken advantage of by Ernest, that Jennifer must be killed upon her return, in order to keep everything under cover.
Output (English): What are the first names of the two people who were killed by the unseen?
