Answer 2

Thank you very much. I have a question, forgive my ignorance. When the question refers to 20th Century, exactly what time frame should be covered like from what year to what year? Thank you very much.

Answer 3

1901 to 2000, but the others before that really had a bearing on the changes. I frankly don't know how one can separate them.

Thank you and good point!
