Answer :
Answer:
Upgrading the chosen vehicle
Downgrading the unchosen vehicle
Explanation:
The term dissonance is used to describe the feelings of discomfort that result when your beliefs run counter to your behaviors and/or new information that is presented to you.People tend to seek consistency in their attitudes and perceptions, so when what you hold true is challenged or what you do doesn't jibe with what you think, something must change in order to eliminate or reduce the dissonance (lack of agreement) and that's why she has to upgrade the chosen vehicle and downgrade the unchosen one.
