20th centry pop culture and the arts, Art & Design Homework Assignment Help

I do not know much about art at all. I need to check out this site – http://armory.nyhistory.org/category/artworks/,  and then determine which forms of art from the website are interesting, either appealing or unappealing. Also need to determine what works of art was scandalous at that time, and what would still be considered scandalous today.  

How did the Armory Show more
generally help artists to find a collective voice for Modern Art in
America?  What were some of the positive (and negative) effects of the
show?  And what are some of your favorite examples of art that were
included in the Armory Show?
