Q: 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: Vampires are finding their own undead bodies being mutated by the pollution of the host's blood, tainted with hard drugs and sexually transmitted diseases, alcohol, diabetes, anti-depressants, and cigarettes: substances that change the blood and makes it undrinkable for vampires.  The scarcity of good blood has incited an underground civil war between various groups of vampires.  A clique of 4 vampires, led by Benedict, struggle to find sustenance by seeking victims with untainted blood.  The group is being stalked by a samurai sword-wielding vampire-killing Priest, who leaves a note on the bodies of slain vampires in the form of a playing card inscribed with the words "Live Evil".  In order to survive both their race's own fierce infighting and the biological pollution found in human blood, the group desperately seeks out Max, a "blood pusher" who steals from hospital blood banks to offer the freshest and purest blood around. But they may not have time to enjoy it, because the vengeful Priest is hot on their trail.
A:
Who does Benedict's group get their blood from?
