Task: Question Answering
Input (English): Passage: Barry is a formerly successful insurance executive whose career and life are being destroyed by alcoholism. As the day ends, he is sent to a notorious New York City housing project, the Lincoln Towers, to try and complete a life insurance policy sale to a nice elderly woman named Elva. Meanwhile, a man named Will, a soft-spoken but tough employee of the telephone company, also heads to the building to hook up with his girlfriend and repair the phone lines. Unfortunately for Barry, while inquiring where Elva's apartment is, he taps a boy on the shoulder and quickly becomes the hated target of a savage gang called the Vampires, who run the Towers. The gang is led by their ruthless leader the Count.
An attempt to kill him leads to the death of the building's security guard. With Barry's entrapment inside the building, he crosses paths with Will and makes his first reluctant ally willing to help him. They take safety in Elva's apartment, but escape when the Vampires trap them. Leaving Elva behind, they find Elva's determined granddaughter Toni, visiting with her neighbors. Toni suggests they go to the apartment of Mr. Parker, a unstable yet vicious Vietnam vet the gang fears. Paid for his help, Parker lets the trio in. Then Toni leaves to check on her grandmother. When she arrives, she discovers Elva had been beaten and forced to reveal where Barry and Will are. 
Question: Who fears Mr. Parker?
Output (English): the Vampires.
