US History from 1890-1940 questions?

Sorry, I don't do homework for people too lazy to search for them on the internet. Hint, put phrases in quotation marks, such as "Dust Bowl", "New Deal" and "Bonus Army" and you will get better results. Add further keywords or phrases to further narrow the results. Example: [ "Federal Government" +"New Deal" +funding +programs] = a href="http://www.google.com/search?q=%22Federal+Government%22+%2B%22New+Deal%22+%2Bfunding+%2Bprograms&sourceid=ie7&rls=com.microsoft:en-us:IE-SearchBox&ie=&oe=&rlz=1I7RNTN_en" rel="nofollow"http://www.google.com/search?q=%22Federa…/a
