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: Bob Webster, aka Bat Williams, is a career criminal who keeps his parents and siblings in the dark about his chosen career by pretending to be an engineer who is often away in different parts of the world on assignments. He uses this ploy not only to disguise when he is out of town engaged in criminal activities, but also to cover the times he has been sentenced to prison. After receiving a parole from prison, he rejoins his gang, including his gangster girlfriend, Grace Forbes in robbing a creamery. A robbery during which they kill a clerk who can identify them.
After the robbery, Williams leaves the gang and returns to his family's home in upstate New York. His father, John, his mother, Helen, and his sister, Mildred, all think the world of Williams. During his stints in prison, he sends one of the other gang members to different far-away locales, in order to mail a post card to his family, pretending that he is working there on an engineering job. During his visit, he overhears his father on the phone with the Governor, who is asking John to serve on the state parole board. Fearing discovery, Williams tries to convince his father not to serve on the board, but John won't commit one way or the other. While in his home town of Barlow, he also runs into his old girlfriend, Letty Graves. To impress Letty, Williams breaks into a jewelry store and steals a bracelet, but kills the security guard so that he can't identify him.
