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: At the trial, Pisciotta said: ``Those who have made promises to us are called Bernardo Mattarella, Prince Alliata, the monarchist MP Marchesano and also Signor Scelba, Minister for Home Affairs ... it was Marchesano, Prince Alliata and Bernardo Mattarella who ordered the massacre of Portella di Ginestra. Before the massacre they met Giuliano...'' However the MPs Mattarella, Alliata and Marchesano were declared innocent by the Court of Appeal of Palermo, at a trial which dealt with their alleged role in the event. During _his_ trial Pisciotta could not account for Giuliano's documents in which he named the high-ranking government officials and mafiosi involved with Giuliano's band. <sep>, Pronoun: his <sep>, A: Alliata <sep>, B: Pisciotta
