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
Reason: Based on the text, his refers to MacKenzie so option A is correct.

Now, solve this instance: The Adventures of Sam Spade was a radio series based loosely on the private detective character Sam Spade, created by writer Dashiell Hammett for The Maltese Falcon. The show ran for 13 episodes on ABC in 1946, for 157 episodes on CBS in 1946-1949, and finally for 51 episodes on NBC in 1949-1951. The series starred Howard Duff (and later, Steve Dunne) as Sam Spade and Lurene Tuttle as _his_ secretary Effie, and took a considerably more tongue-in-cheek approach to the character than the novel or movie. <sep>, Pronoun: his <sep>, A: Steve Dunne <sep>, B: Sam Spade
