In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: Sergeant First Class Buck McGriff and Sergeant First Class Albaby Perkins are two joint services Criminal Investigation Division agents on duty in war torn Saigon.  When a prostitute is found murdered they discover that the prime suspects are high ranking U.S. Army officers.  As they investigate they find that there have been a string of at least six murders in the last year, but the previous inquiry was shut down from higher up the chain of command. Investigations lead them to Colonel Dexter Armstrong, but Armstrong rules himself out of inquiries by committing suicide. With the help of a French nun Sister Nicole and their non-commissioned officer in charge, Master Sergeant Dix, they finally close in on their target. As their investigation leads them closer and closer to the murderer, they find their lives are in danger and they end up nearly being sent home. The movie ends with an unexpected twist when they rule out all their suspects by conducting an interview in a Viet Cong tunnel base, and their NCO is the killer.
What is the full name of the characters who learn of a string of six murders?

Passage: Derek Charles works for a finance company and is married to Sharon. While Derek is at work, he greets temporary worker Lisa Sheridan, who, believing Derek was flirting with her, attempts to seduce him. Derek repeatedly rejects her, but Lisa continues to pursue him, making sexual advances on him at the Christmas party. At one point, she follows him to his car and attempts to seduce him again with revealing lingerie and fishnet stockings, but Derek refuses again and forces her out of his car. Derek intends to report Lisa to his firm's human resource management, but learns that she has quit her job. Thinking that Lisa has given up, Derek is annoyed when he receives flirtatious emails from her. Derek and his workmates visit a resort for a conference, where he spots and confronts Lisa, who spikes his drink. Incapacitated, Derek is helpless when Lisa follows him into his hotel room. He confronts Lisa again the following day, and hours later discovers her lying naked in his bed after attempting suicide, and calls for medical help.
Whose husband had his drink spiked?

Passage: Paul Blart lives in West Orange, New Jersey, with his teenage daughter, Maya, and mother, Margaret. Aspiring to join the New Jersey State Police, he trains at the police academy, but his hypoglycemic medical condition causes him to collapse, therefore failing the exam. To shape up for his career, Blart works as a security guard at the fictional West Orange Pavilion Mall.
Blart patrols the mall on a Segway to assure that things are safe and clean. He also trains Veck Simms, who is new but uninterested in the job. Meanwhile, Blart becomes acquainted with Amy Anderson, the vendor of a new kiosk. He meets her one evening at a party at Joe's American Bar and Grill with other mall employees. Things initially go well, but Blart is sidetracked when he decides to participate in a nacho-eating contest with his friend Leon. The hot and spicy salsa is more than Blart can handle, causing him to inadvertently drink several alcoholic beverages. He ruins the party and makes a wild exit by falling through a window.
Two days later, on the night of Black Friday, an organized gang of thugs disguised as Santa's Village employees begin what appears to be a bank heist inside the mall. They take Amy and other customers in the bank hostage. Simms is revealed as the gang's leader – his mall security job was a ploy to gather intelligence. They are keeping the hostages as insurance for the gang's escape. The crew force shoppers to exit the mall and strategically place motion sensors around each entrance to detect any attempt to enter or exit the building.

Who does Paul Blart become acquainted with before the nacho eating contest?
