9.(Both)  government  and private industry (make use of ) (cryptonanalysis), that is persons who (make) and break codes.

19.Palo Alto, California, is (home to ) some of the world's (foremost) (academic), (medicine), and research institutions.

9. make use of --> makes use of

19. medicine --> medical

ps：用括号标明错误就可以了。多加的abcd，看起来特别扭。

qinxing

9.cryptonalaysis-----cryptonalaysts.

19,academic（adj), medical(adj) and research(n,v) 并列吗？
