What made The Pillow Book unique?

It was a book many Japanese women used to learn to read and write Japanese.
It was one of the first books in Japan written by a woman, Sei Shonagon.
It was the first book of Tanka poetry written by Yamanoue no Okura.
It was the first book written by a woman to be classified as literature.

Respuesta :

If you look up the Pillow Book, it was written by Sei Shonagon and is a book about her observations of Japanese court life. So you can definitely rule out A and C as they are blatantly wrong

I would say B is the correct answer

It could be D instead to be honest, but since it's more of a memoir - might not be classifed as literature. The first book written by a woman that COULD be classified as literature is the Tale of Genji published around the same time as the Pillow Book, also in Japan.

Historians are not 100% sure which one was printed first anyway 
"B" is the correct answer.
