A. Why are so many young women getting pregnant?

B & C. All of the methods would be good to use. I would need to survey lots of teen as well as their families. I would ask lots of questions. Such as, how was childhood for them. What parents were in the home. What kind of health classes they had. I think that survey would be good because you can ask direct questions and learn their values and upbringing and what they learned through childhood. Observation would also be really good so that you could see what teens go through with pure pressure, everyday life, school, etc.

C. I would go to schools and give surveys as well as mall and other teen hangouts. There are many questions to ask. Values, religion, upbringing, are all factors. Different cities would have different percentages and why.

D. Ethical issues will always get in the way. There would be conservative christians that say sex is for marriage, but even preachers teens are having sex. Also in surveying teen you have to be careful of what you ask and how. I would get parent permission if needed for the surveys. I would not judge so there couldn't be biases.
