Using sociological imagination, analyze the scenary: Susy is a sophomore in college and get pregnant. Her boyfriend end up the relationship. Susy now drop all her classes

I don't know exactly what you want. But in this situation, Susy needs to rely on family to provide support: Susy needs to call Mom urgently.

I am not certain what sociological imagination means....perhaps that is the same imagination that got Margaret Mead into research results, perhaps not.
Frankly, I am surprised that your instructor used the term.
