How to phrase research question? ( quick please!)?

okay so i want to write a paper on stem cell research. specifically alterante ways of getting stem cells that are ethical. for example getting them from adults or the umbilical cord. because those 2 ways cause no damage.





these are some things my teacher wants:


1. it has to be a question (i was going to do alternative methods of stem cell research)


2. it has to be specific. narrowed down


3. she doesnt want something that is over talked about





so some i was thinking about are:





1. what are some alternative methods of stem cell research?


2. Can stem cell research be an ethical option?


3. When is stem cell research ethical?





i dont really know haha


so any of those? or if you can think of a better one?





..or maybe if you thinki should switch the topic completely.


thanks!
