The challenge that Sarah faced was finding lots of money and decided not to take any when she could have . Even though she needed more ,The competition would be deceitfulness and dishonesty. Her resources were money ,and needing stuff for her birthday . She got credibility from her character and responsibility of not taking money from someone else. I guess a way she showed creativity was finding a way to get the lady her wallet . Uncertainty can be how she made a decision if she wanted to take some money or not . I don't think there was anything unfair for her because in the end she got what she wanted . Integrity she didn't take any money from the lady and got rewarded.
