Task: Question Answering
Input (English): Passage: In the 1970s, Bay City Police detectives David Starsky and Ken 'Hutch' Hutchinson are forced to work as partners. The macho Starsky loves his Ford Gran Torino and recklessly pursues minor offenders, while the easy-going Hutchinson often works alongside criminals to investigate their activity. Jewish-American drug kingpin Reese Feldman and partner-in-crime Kevin Jutsum develop a new type of cocaine untraceable in scent and taste. When one of his dealers botches an operation, Feldman kills him.
The body washes ashore a few days later, and Starsky and Hutch investigate the scene. A clue leads them to Feldman, who denies any knowledge of the crime, but his wife mentions the dealer had been dating a cheerleader. After meeting cheerleaders Stacey and Holly, the detectives learn from cheerleader Heather that the dealer's jacket was made by Big Earl. Their street-wise informant Huggy Bear directs the pair to Big Earl's motorcycle bar. Disguised as "Captain America" and "Billy" from Easy Rider, Starsky and Hutch learn Big Earl is in jail, where they question him on his connection to Feldman's illicit dealings. Big Earl, implied to be gay and obsessed with dragons, forces the detectives into humiliating acts in exchange for a packet of what they believe is cocaine. Captain Doby, angered by their wild interrogation, tells them the packet contains artificial sweetener and takes them off the case.
The duo invite Stacy and Holly to Starsky's place where Starsky puts the "sweetener" in his coffee while Hutch sings Don't Give Up on Us (first recorded by David Soul, the original "Hutch"). The four visit a disco where Starsky, suffering the effects what proves to be Feldman's modified cocaine, loses a dance-off. Hutch takes him home and proceeds to have a threesome with Holly and Stacey. 
Question: What are the names of the women Starsky's partner sleeps with?
Output (English): Stacey.
