Problem number six. Araf folds the transparent paper along the dashed line. What can he see? Here's a close-up of the paper. When Araf folds the paper across  this line, these lines on top will show up on top of the bottom lines, but they will be flipped across this line as though it's a mirror. So I'm just going  to draw these in. The first line starts close to the fold line, so it's going to go here. The second line is further away from the fold line, so it's going to go  over here. This next shape, the long line, goes all the way down, and then this line from the top will be on the bottom of this figure. The last one, these four  lines form a square, and this square will be further away from the fold line, so it will be here. So what Araf sees looks like the number 406, and this is answer E.
