The purpose of a timeline is to list major events according to what happened first, next, then last. I have given you the main idea please finish the paragraph yourself.
1- A
2- D
3- B
The thing about 3 Is that there were many taxes if one went buy land, so Only the rich took that path
C. China
China provides many services and things to the rest of the world, but like it says in the passage, there is still a lot of poverty.
