The correct answer is E) Wendy, whose older brother finished college last year and serves as a role model for her.
Step-by-step explanation:
Factors such as family, habits, personality traits, among others, influence to a great extent the way people behave and think and therefore are determinant on whether an individual achieves a specific objective, for example, completing a senior thesis.
In this context, a positive role model such as an older brother will influence positively a student to complete this goal faster. This means, in the case of Wendy because there is already someone in her family who finished college and because she wants to emulate his behavior and achievements, it is likely she is highly motivated to complete this goal and can do it faster than others; besides, her brother could help her in the process. Also, attitudes such as being a rebel, unrealistically optimistic or considering one as not efficient do not help students to focus on a goal and complete it in a short time.
