Why are the last two images in this series different from the others?
Thank you -- I already wrote the key for the first fourteen of these without breaking a sweat the blood/brain barrier, and I need to finish it for tomorrow.
I think their thing is wrong (or at least that the problem is ambiguous and has more than one reasonable solution). The 4th and 5th ones are the odd ones out because in the other four if you draw a line segment between the ends of the curvy line, they're incident with a corner of the rectange.
Also, the average citizen only gets two problems right?
I'm just eyeballing this, but here's my guess: If you draw a line segment between the ends of the curve in each picture, that segment will cut across the rectangle in the last two images, but not in any of the other ones.
