Crystal's Best Friend Kerry Complains About Her Boyfriend All the Time

Crystal's best friend Kerry complains about her boyfriend all the time: how he was late for their date and how he never brings her flowers. Because Kerry feels she can vent to Crystal, she uses their time together to work out her frustration with her boyfriend. Consequently, when Crystal meets Kerry's boyfriend for the first time, she focuses on what she doesn't like about him rather than listening to him discuss the trip he is planning to take Kerry on or how crazy he is about her. To become a better listener, Crystal needs to

A) avoid the confirmation bias.
B) separate what is and isn't said.
C) listen for substance more than style.
D) be a skeptic.
