Who is most likely to become a successful entrepreneur?
a person with a Ph. D. in biomedicine who enjoys research at a hospital
a technician who wants to make a million dollars selling supplements
a nurse with a marketable business idea who knows his client base well
a medical writer who is tired of her boss and has some leadership skills

a nurse with a marketable business idea who knows his client base well

Explanation:

For becoming a successful entrepreneur, you need to have a business idea, and you should know how to tackle the clients. Even if you are Ph.D., since you are dealing in research, you can be good for education, but not for business. And if you do not know how to deal with the boss, and also since you have incomplete leadership skills, you cannot be a successful entrepreneur. Hence, the correct answer here is the nurse option.
