I believe that you’re talking about The Night to Remember by Florence Wilmingon. In this text the writers began telling the reader that Marian is one of her favorite singers and then start telling about Marian’s life and how amazing she is and how her song brought tears into her eyes and in the end of the text the writers one more time shows how she likes Marian "The power of Marian’s astonishing voice had captured their hearts as well as mine". The answer is C "She is biased in favor of Marian Anderson."
