This question makes absolutely no sense to me and it is driving me crazy that I cannot find a solution. Maybe it is nonsensical, maybe my IQ isn't that high :P. Thanks a lot!
green, blank, blank.
calling the cells A,B,C,D,E,F and examples 1,2,3,4,5
1-2 deonstrates that B is the opposite of D
It can also be deduced by looking at 1,2,3,4,5 that A,B,C are not correlated with each other
then it can be seen that A always matches F and C always matces E
leaving only one of the patterns offered as the answer.
3 and 4 identical hints that there is no vertical sequence
5 being half filled suggests that the D,E,F are can be determined by A,B,C
it took me a lot longer to deduce this than the time I allow to answer most IQ test questions.
Extracting a pattern from so little data will always be ambiguous.
My guess would be
Green, blank, blank
because if we assume there is an independent operation for deducing the fifth element in a column from the other four, we have existing samples for the fifth and sixth column, and only one answer choice that fits both.
I notice that there are 3 shaded (blue) blocks and 3 non-shaded blocks per row.
From this alone, I can tell that the likely solution is(final row):
u = un-shaded, s = shaded
Given: u, u, u;
Solved: s, s, s;
Final: u, u, u, s, s, s
