Dear diary...

This day's question: The Diary of Anne Frank is one of the world's best known diaries. How many people have read it since it was published in 1947?

c) 31 million

The audio seemed to me to be interesting, since the book of anna frank's diary I gave it last year to my brother and I also read it and I like it enough.
The audio did not turn out to be easy, since I have listened to it for the second time and with the text there are any neil's answers that do not turn out to be written, only it puts answer.
The vocabulary is clear and it helped me enough.
