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: 46-year-old former high school dropout and self-described "junkie whore" Jerri Blank is released from prison and returns to her childhood home. She discovers her mother has died, her father, Guy, has remarried to the hateful Sara Blank, and she has an arrogant half-brother Derrick. To make matters worse, her father is in a "stress-induced coma". Taking the suggestion of the family doctor literally, Jerri decides to pick her life back up where she left it, beginning her high school all over again as a freshman at Flatpoint High.
Jerri joins Chuck Noblet's science fair team, the Fig Neutrons, along with her new friends, Megawatti Sucarnaputri (a spoof on Megawati Sukarnoputri) and Tammi Littlenut. Noblet is not pleased to learn that Principal Onyx Blackman has hired a ringer for their team, Roger Beekman, to ensure that Flatpoint wins, and so Noblet creates a second team. As she struggles to fit in and make her teammates proud, Jerri discovers that though the faces may have changed, the hassles of high school are just the same.
A:
What is the full name of the person who has an arrogant half-brother?
