A community to collect images of ravens progressive matrices.
I thought these are fun puzzles; So I made this community. Rules: Post an image of a ravens progressive matrix test question, then post the solution in the comments with a spoiler tag. If possible, add a source.

Solution: e.
What will you fill in for #?
Solution
Black filled star.
Each row and column has to contain each kind of pentagram.
Also: I think it is the diagonals? Similar to determinant rule application.
Black star seems inevitable. Otherwise it would be the only row with no black star. Also, it would complete the pattern of black star moving from 1st to 3rd position.
It also is a perfect fit for a sudoku style with every symbol appearing not only once per line, but also per column. And completes "3 of every kind of symbol".
This is so simple, it looks like the IQ test from the prison in the movie Idiocracy.
There are multiple potential ways of solving this, and I concluded early on that "nah, it can't be that simple". So I went through the ones I could think of just after waking up at the crack of noon.
Row sequence.
Column sequence.
Diagonal sequence (with wrapping).
They all came down to a simple XOR, so Black Star.
can you expand on the xor reference? I do not see the connection to boolean logic? You mean its an all unequal relation for rows and columns?
For instance, compare the first and second columns. When you examine corresponding segments of the two stars, the third column will be shaded only if the segments in the first two stars differ in shading. In other words, it behaves like an XOR operation.
Same as B F or G, white center black tips
