J.-- Your questionnaire is both too broad and too vague to gather the data you say you are interested in--that is, your questions wander far from the subject of evolution in natural history museums, and it is hard to tell what the questions are asking for--a term paper?--because some would require very extensive answers. Suggest that you rework your research question (narrow it down, get a focus) and rework your questionnaire before spewing it out on the museum list. Thanks.
