22.A Cross and grey square remain in the same positions. Black square rotates clockwise. Black square covers other squares.
23.B All squares are the same as bottom middle but shifted. Could also work out with three sets of three rule.
24.C As in 18.
25.D Left column is original shape. Rotate middle column 90 degrees clockwise and squish original shape in opposite direction to those presented.
26.A Left column overlaps shape in middle column.
27.D Reading columns left to right the tiny blocks increment by one each square so final must have 3 squares. Three sets of three rule shows it must be in that position.
28.E Three sets of three rule. Rotates clockwise each row.
29.C Black squares and white squares are independent variables. The side of the line indicates negative v positive. I'll use the first row to explain. Left has 3 white and 1 black. Middle has 1 black and -2 white. Addition gives 2 black 1 white.
30.F As in 18.
31.A As in 18.
32.D I have no idea why though.
33.C Three sets of three again but sets aren't arranged normally. Original shape is one set, other two sets are the original shape with an action performed on them. Original shapes are middle, top middle, middle right. One set of actions is reversing the sides eg middle v top right. This set is complete. Incomplete set is the other action, taking original shape and flipping right side both horizontally and vertically eg middle v bottom middle.
34.E Unsure if this is a complete explanation but the left and middle are added to produce right. A small and a big produce a big while others have no effect.
35.F >>9173341 >>9173351 is correct.
