Given the task definition and input, reply with output. 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: Ann Martin is two years into a five-year prison sentence when she is granted a conditional parole. A job and new life in a small town are waiting for her, with candy store owner Ed Praskins vouching for her and promising to produce regular reports on her conduct.
Bill Phillips, a pharmacist, introduces himself to Ann and attempts to know her better. Praskins then stuns Ann by revealing he is fronting a criminal operation run by George Trent, who is targeting a wealthy widow in town, known to all as Madame Rousseau, whose hidden cache of a valuable oil used in perfumes could be worth a fortune.
Ann is given false references and becomes Madame Rousseau's assistant and companion. Trent has already planted a chauffeur there named Foster, whose inability to keep a secret results in Trent murdering him. A distraught Ann, having developed a genuine fondness for Madame Rousseau, learns that Bill is hiding the precious oil. Trent tries to steal it, but Bill, actually working undercover, is ahead of him all the way. Ann must return to prison. Madame Rousseau, however, promises her a job when she gets out.
What is the last name of the person Ed promises regular conduct reports on?
