How is Hannah Hoch's use of photography different than other artists studied in chapter 9? O she used interesting lighting techniques
O she used found images from other sources
O she mixed her own photographs with found images
O she only shot in black and white

Well we cant say like the watercolor is better or drawing is the best all of them are good and beautiful. it depends what do you like so maybe some one likes watercolor and thinks thats the best and maybe someone else doesnt like it and even you cant say which artist is the best ! :)))
i hope this is helpful 
have a nice day
