### Stupidly hard quiz

This sentence is self-referencial.
So is this quiz!

Make sure you're not doing anything for the rest of the day.
I've filled in two answers, and I have little to no idea of how to progress.

Why did the vector cross the road?
It wanted to be normal.

Oh geeze I hate these, I posted one in Coder's Corner once. I have no idea how to get started on them! They're just a jumble of information to me!

### Re: Stupidly hard quiz

Man is that one crazy quiz!  To have any hope, I'd have to print it out first before even thinking of attempting it online.  It reminds me of real exam questions I've had to do where there are three statements (X, Y and Z) and the possible answers are along the lines of:
A: X and Y are correct but Z is incorrect
B: X and Z are correct but Y is incorrect
C: Y and Z are correct but X is incorrect
D: X is correct but Y and Z are incorrect.

### Re: Stupidly hard quiz

I was able to find 2 questions logically. (#10 and #16).

However, I think this quiz is impossible because of questions like this:

19. The answer to this question is:
AA
BB
CC
DD
EE

WTF?

The answer you give will obviously always be right, but you may need to pick a specific answer in order for other answers to be right (like "5 of these questions have answer A", or something.)

For a similar reason, you can't necessarily say that #9 can be answered using #10 and #16.
They lead to a possible answer, but you can't say that's right until you eliminate all the other ones.

Edit: After a good two hours and a piece of paper filled with scribbles, I've now got it.
#2 and #13 provide useful restrictions that can help.
