I would say:
-cities
-specialized labor
-communication and writing
-moral code
Hope I helped :)
It would be the 4th amendment. This is because the fourth amendment gives people the right against unreasonable search and seizures. This is where probable cause and the exclusionary rule come into effect!

To be honest I don't think this is worth stressing over you get to meet a great person who did a lot to make this future I think the best thing you could do is stay respectful and just say it if you feel the need to. Thank you so much. It doesn't hurt if you do your research on that specific person if you want to ask about specific events they were involved in
