So simple that it requires so many words to explain ;)

  Actually, the SAT reading comprehension questions are not that simple and trip people up. Which is really my point of analogy. They're the kind of questions where you either got the right answer or not, but explaining it to the person who got it wrong can be non trivial.

    Almost an opposite of NP problems. Easy to solve, but hard to convince someone else that your solution is correct.
