Help for choosing topic for my primary research report

[The_White_Paradise]

Now, I am searching for topic for my primary research report. I have not found any interesting topic until now. Topic must belong to " culture" and " education". However, I prefer topics about "culture". I think those will be easy for me to give presentation about writing topic. And the topics about culture will interest reader (professors), listener ( my classmates when I present) or subjects ( people help me answer the questions when I conduct surveys) more than those about education.
I am confused because I don't know how to find topics are relevant for primary research report .
So, Could U help me give your advice about where I can see topics, sources for it and your experience ?
Thanks!

well, you can talk about the differences among cultures (maybe just between two cultures).

you can choose to write about the "car culture" difference between north america and vietnam. You know, in vietnam a motorcycle can work as a mini van, which can carry the entire family... lol but in north america, lots of families have more than one car and they have drive because they live in massive lands.
