Final answer:
According to self-evaluation maintenance theory, Tanesha is likely to feel threatened by Amber's victory in the city championship.
Step-by-step explanation:
According to self-evaluation maintenance theory, when Tanesha, who considers herself a top-notch golfer, is defeated by her friend Amber in the city championship, Tanesha is likely to feel threatened by Amber's victory. This theory suggests that individuals tend to feel threatened when someone close to them outperforms them in an area they value highly. Tanesha's ego and self-esteem may be affected by Amber's win, leading her to feel threatened and potentially impacting their relationship. Tanesha may try to downplay and rationalize Amber's victory as a one-time occurrence, but the initial reaction is likely to be feeling threatened.
