From AP today:

...The federal government today is unveiling 144 draft questions that it plans to try out on immigrant applicants next year in 10 cities....

The redesign is aimed at making sure applicants know the meaning behind some of America's fundamental institutions and historical events....

Immigrants now are asked "What are the three branches or parts of government?" The answer: executive, legislative and judicial.

But a draft test question asks: "Why do we have three branches of government?" Acceptable answers might be, "so that no branch is too powerful" or "to separate the power of government," Rhatigan said.

And we're sorry, Vice President Cheney, but "So the executive branch can have two other branches of government to crush underfoot like so many noxious worms!!!" would not be considered an acceptable answer.
