The answer should be F, not B. The pattern is when there is solid line, rotate 90 degree, it does not matter with whether the position is next to each other or not. Dotted lines rotate 45 degrees.

The case for option B is stronger, as it outlines transformations that start from the leftmost cell for both the solid line and the dotted line.

to answer why its not F. you are forgetting to do a rotation. you are assuming that from the far left square to the far right one it only rotates 90 degrees once. but you are forgetting that it rotates once already to go behind the dotted line in the middle square. and then once again to become horizontal while the dotted line rotates another 45 degrees clockwise.

A solid line form, single or cross, rotates 90 % moving linearly within each row. A dotted line form, cross tick or single, rotates 45 % clockwise moving linearly from left to right within each row and obscures a solid line that it overlaps.

Shouldnt it be F, rather than B, because a vertical solid line would form a cross if the solid lines in each row are overlapped?

That's an interesting concept, however it leaves out the behavior of the dotted line; also the case for the answer being 'B' is stronger:

Option B describes the following transformations:

1. Dotted lines rotate 45° CW.

2. Solid lines rotate 90° CCW.

3. Dotted lines hide solid lines.

I am curious: How does F leave out the behavour of the dotted line?

My first interpretation was:

1. Dotted line rotates 45

2. Solid lines appear once in each row, together or separate.

I do agree the case for B is much stronger, and is the best answer.

Hi Ann, that was a typo in my message above, I should have said '..leaves out the behavior of the solid line'. The solid line rotates 90° instead of appearing at a right angle to the other solid line in each row. Furthermore, it is hidden by the dotted lines.

Lol. This is the only one out of the ten that I got wrong and it's clearly a mistake by the test designers. The answer should unequivocally be B. There is no possible way for it to be F.

Explanation:

Dotted lines rotate 45 degrees and solid lines rotate 90 degrees. When they both arrive at the same position, dotted lines hide the solid lines. Following this line of logic, the solid line must be in the vertical position in the second column. Last I checked, rotating a vertical line by 90 degrees makes it horizontal which leads you to answer B.

Thanks for pointing this out Phil.

Na. The solids rotate 90 and the dots rotate 45. Dots overlap solids.

This is a rotation of sticks. You have to notice that all sticks from the beginning rotate at the same degree per picture, and bold-type sticks also do (but not same degree/pic as the dash-type sticks). With this being said, if bold sticks rotate to the same position as the dashed ones, the sticks are canceled out of the picture. The opposite can be said for the dashed sticks.
