Please help me with these questions they are really hard and I just can't figure them out!?

i'm not about to do your homework (or whatever this is) but i can give you a really helpful clue on solving it: there are many books in the library that deal with western civilization , china, china's development, etc. some devote their entire contents to china & its development. there are 19 slots & there are not 19 words to use for fill-ins. i presume some are repeated. not sure which to use. begin first with knowing what each word means/implies & go from there.
