1.Radiocarbon dating is when scientist find somthing old and find how old it is. they do this by measuring the carbonaceous materials. this is very helpfull. However there are somthings that are wrong with this process. One thing is that they dont always do it with the item that they want to no how old it is. They will use somthing closer to it and say it is the same old. another problem is the tecnolagy has changed. So like twenty years ago the mathmatical steps could have been wrong.
2. I would have lived in china because they have very good food. I liked how there old buldings looked.
