Here is a problem for the world's best and the brightest to ponder about? Can anyone answer the following questions.
10) Which of the sentences below cannot be wrong? Explain.
a) The Earth orbits the Sun.
b) Cats cannot lay eggs.
c) You cannot be me.
d) If João is Pedros son, João was born after Pedro.
e) The choices a and b are correct.
f) The choices a and c are correct.
g) The choices a and d are correct.
h) The choices b and c are correct.
i) The choices b and d are correct.
j) The choices c and d are correct.
k) The choices a, b and c are correct.
l) The choices a, b and d are correct.
m) The choices a, c and d are correct.
n) The choices b, c and d are correct.
o) All the above are correct.
p) None of the above is correct.
My first answer would be O; as if all the above are correct e) through to n) would be correct, the Earth does orbit the sun, Cats are mammals and give birth to living young, you being me would be illogical and João is Pedros son.
Boy let me tell you what:
I bet you didn't know it, but I'm a fiddle player too.
And if you'd care to take a dare, I'll make a bet with you.
Zach's right, unless you're a philosopher who refuses to believe anything.
For a), Einstein's relativity thing says that it might be the sun moving around the earth and we wouldn't know the difference.
For b), I can't think of anything good. It's a long shot, but I suppose you could say that a cat might pick up an egg and then lay it down somewhere.
d) is possible through adoption, although it would certainly be strange.
[...And I would have proved c) possible by posting as a guest, but that's been disabled now.]

Why did the vector cross the road?
It wanted to be normal.
I concur with Zach's and mathsyperson's views, although I find mathsy's counterexamples quite funny!
It is no good to try to stop knowledge from going forward. Ignorance is never better than knowledge - Enrico Fermi.
Nothing is better than reading and gaining more and more knowledge - Stephen William Hawking.
