Teacher: In this task, you will be presented with a text, a pronoun from the text, and two candidate names. You should determine what the pronoun refers to and classify the answers into A, B, or Neither. A and B here are referring to option A and option B. Position of the pronoun in the text is showed within two "_"s.
Teacher: Now, understand the problem? If you are still confused, see the following example:
He grew up in Evanston, Illinois the second oldest of five children including his brothers, Fred and Gordon and sisters, Marge (Peppy) and Marilyn. His high school days were spent at New Trier High School in Winnetka, Illinois. MacKenzie studied with Bernard Leach from 1949 to 1952. _His_ simple, wheel-thrown functional pottery is heavily influenced by the oriental aesthetic of Shoji Hamada and Kanjiro Kawai. <sep>, Pronoun: His <sep>, A: MacKenzie <sep>, B: Bernard Leach
Solution: A

Now, solve this instance: Clyde Apperson (born 1955 in Sunnyvale, California) was arrested in 2000 for allegedly running the largest illicit LSD manufacturing operation in the history of the United States with partner William Leonard Pickard. In 2003 Apperson was sentenced to 30 years of imprisonment without the possibility of parole. While _his_ partner Pickard had an extensive criminal history dating back to 1964, for numerous charges ranging from forgery and false identification charges to arrests for manufacturing controlled substances and carrying a concealed weapon, Apperson had no criminal record prior to his conviction. <sep>, Pronoun: his <sep>, A: Pickard <sep>, B: Apperson
