IQ Puzzle #2 - Explanation

So this one is a little bit harder to understand but I hope my illustrations will help. Essentially the symbols had 2 parts, the red circle with a hole and the green parallel lines. The red circle rotated at a constant rate of one 1/4 turn clockwise throughout. This means that the next symbol in the series must have the opening facing the top. This narrows down the possible answers to (C), (D) and (E). The second part are the green parallel lines that rotate in an addition series. That is to say that from the first symbol to the second there is 1 rotation of 1/4 turn clockwise. From the second to the third there are 2 rotations of 1/4 turn clockwise. This continues linearly so that from the third to the fourth there are 3 rotations, then 4 rotations, 5, 6, 7 and finally 8. The second to last symbol has 8 rotations and that means that the sticks will encompass two full rotations ending up facing straight up and down again. This means the answer is (C). Hope this makes sense! If you have any questions just ask in the comments!

    Yeah, i've never really been good at this stuff. I get lost on the 5th block.

    I guessed E because I started seeing the sequence based on columns. I think I still might be right.

    I have tried solving for E and cannot see the pattern, care to explain Allen?

    I couldn't tell what pattern the lines were going, it's so simple seeing it now though.

    Again, something I think I should be able to do that totally stumped me.

    I get the red progression, I don't get the green progression. I guessed C or D, but don't get why it couldn't be either. Why is C more right than D?

    @convictus - For this one it has to be C. In terms of the progression for the green lines you count the distance in terms of quarter turns between the top left, middle left, middle left, top left etc. You will see it goes 1,2,3 etc. If you want I can draw out a better explanation for you - just let me know.
