Final answer:
According to research, most girls her age realize that motherhood may affect their career choices.
Step-by-step explanation:
According to research, if Susanna is typical of most girls her age, she realizes that motherhood may affect her career choices. This is supported by the fact that many women in the past had to make sacrifices in their careers due to motherhood responsibilities, as seen in the examples of Susie, who dropped out of college to raise her child, and the challenges faced by women in the workforce in the 1960s. It is unlikely that Susanna would not let her family aspirations interfere with her career choices, as historical evidence shows that motherhood can impact a woman's career.
