(Nghe cuộc trò chuyện với cuốn sách của bạn đóng lại. Tại sao Luisa lại quan tâm đến việc chuyển phát thư trong quá khứ?)

Luisa: Hi, Carl. Can I ask you a question?

Carl: Sure. Go ahead.

Luisa: What do you know about how mail used to be delivered?

Cari: Do you mean letters and packages? Well, I guess they were taken on horseback to places in the same country, and by ship to other countries.

Luisa: Right, so it used to take a really long time.

Cari: Oh yes! When the telegram was invented in the 1800s, people were finally able to send messages quickly.

Luisa: Then, in the 20th century, when the Internet was developed, everything changed in communication!

Cari: Definitely! But why are you asking me about mail delivery?

Luisa: I'm giving a presentation in my history class on how communication has changed over the years. I was just practicing for it!

Cari: Well, I hope I helped! Good luck!

Luisa: Thanks, Carl!
