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: As Madoka continues throughout the next three college years doing the part-time jobs, he is introduced to Sachi Aguma, a high school girl and fellow GSG part-timer who is capable of astral projecting and who has a crush on Nabeshima, despite his insistence that humans and shinigami are not meant to be together. On the other hand, one of the spirits that he has to deal with is revealed to be a high schoolmate, Chisato Ogawa, who has been admiring Madoka from the distance but cannot speak out until _her_ death. <sep>, Pronoun: her <sep>, A: Madoka <sep>, B: Sachi Aguma
