Insert yourself into one of the pieces (painting, photo, poem, short story) from the 20th Century (1900 to 1950)you can also choose an event.  This can be done in a number of ways.  You can put yourself in the position of some figure or element within the work; or you can envision yourself as being present within the piece, some kind of bystander.  Get inside the reality of the work or event. Describe the piece from within, giving a catalog of detail, but detail as one would know it from inside the pieces own internal logic.  Then talk about the work as if it were an event happening to you, and you are attempting to address the importance of the moment. Why are things the way they are? What, if anything, has caused this moment? What bigger issues does it raise? Remember to try to stick to the imaginative logic of the piece, but flesh it out with your own thoughts.
