Tough Silver Age Trivia Quiz #35

This is really, really tough, so I make no apologies:

1. Who thought Americans were all gum-chewing gangsters?

2. What Daredevil villain does the Batman villain the Masquerader resemble? Update: Resemble is the wrong word here; what I'm looking for is the DD villain that the Masquerader has the most in common with.

3. Whose favorite dish was Korala Stew?

4. What do the Blue Bowman and the Trapster have in common?

5. What happened during the Great Evolution?
