Are you smart enough to be an astronaut?

While i posted it should be 'b', there would be another possibility.

Making the case for 'd' it is the only one that has nothing in common with all others, which is also a solution in itself

D was my other candidate before I noticed B lines up diagonally as well. Another thing I noticed just now about B is that all the corners of the center piece supplement the shape and colors it touches outside of it.


i.e. if you put B in the center, the top left shape is black triangle. To the left of it is a light grey triangle, diagonally there's a white triangle and upwards there's a grey triangle. All four colors are touching. This is the same for the other corners of the center B.


So that's four things going for it being B. I think I'm ready to place my bet.

Accepted .. was there already a finnish astronaut?

Nah, just one with Finnish ancestry; Tim Kopra. (our media of course made a big deal about it, small country issues.)

That was basically the same reasoning I used for my answer; I was looking for a symmetry of pattern in the puzzle and the only one I could immediately see was, if "B" was inserted into the center, there was a grouping of the four shapes, all with the same pattern of shadings, in the same order.; I didn't even consider diagonal relationships...


As far as taking my reasoning to my grave, well, hyperbole...


...and I also have no desire to be an astronaut; I have enough difficulty getting across town on the bus...

I can tell you that it demands a lot and I mean a lot more than getting these IQ test correct to become an astronaut.

Yeah but D doesn't match the color pattern. All other squares have the same colors in each location, only the shapes change.
