Answer:
Interview someone in each of your chosen fields.
Step-by-step explanation:
In the context, my friend Lorenzo wants advice from me regarding career choices. He has somehow researched and narrowed down the choices to two choices. Lorenzo wants to know more about the major and the skills required for each of the profession.
I would suggest him to interview someone experience person in this field and get insights from him. It will provide Lorenzo a better understanding of the major selection and it will also create a blueprints of the future paths.
