What did broken glass in anselm kidders breaking of the vessels represent plz fast

The piece "Breaking of the Vessels" was created by Anselm Kiefer in 1990. The overall structure looks like a bookcase, stuffed with papers from Jewish writers, Jewish history, and parts of the Torah. Glass is shattered on the floor, similar to events that happened to Jewish family homes during World War II. 

Looking at your multiple choice answer options, it seems the artist had more purpose for the broken glass than just as a warning for viewers to keep away from the piece. There also does not appear to be a connection between sand and the bookshelf with paperwork. The glass shattered on the floor can be seen as representing the crushed dreams of Jewish people, however, Jewish history and writing would not be the reason that it was broken. The best answer choice would be the last one. The glass is representing any events in history that have held back Jewish culture (writing, religion, history), and they are breaking through the glass that has previously held them back.

Iwould recommend the attic
