Remember Huey, Dewey, and Louie, Donald Duck’s nephews? They dropped out of the public eye once they grew up, but here’s an update:
Huey became a ne’er-do-good wastrel who couldn’t hold a job for more than a day.
Louie was a fast-talking gambler who made his money playing Texas Hold’em.
Dewey was the brightest duck of all. He worked hard in school and university, earned his Ph.D and became an authority on a number of subjects you wouldn’t think ducks knew anything about!
He knew everything about special computer methods(A) (Use last two numbers)
He was an authority on Classical Greek grammar (B)
He contributed articles to magazines, journals and serials in Slavic languages (C) (Use last two numbers)
He was an expert on systems of governments and states (D)
